An ISO 12217-1:2022 small-craft stability translation must preserve the boat’s design assumptions and the technical meaning of buoyancy evidence. People searching for boat stability report translation, recreational craft design category A B C D translation, maximum recommended load terminology or small-craft swamping assessment translation need more than natural-sounding sentences. They need to know which hull was assessed, in what loading condition, what the reported criteria relate to, and which conclusions were actually supported. A translation that quietly turns a design assessment into an unlimited sea-going guarantee can mislead surveyors, manufacturers, dealers and owners.
ISO 12217-1:2022 is the published international standard for stability and buoyancy assessment and categorization of mainly non-sailing small craft with hull lengths from 6 m up to 24 m. It concerns intact boats, also addressing certain flotation or swamping considerations, and can support a design category A, B, C or D appropriate to the evaluated design and maximum total load. Its catalogue includes important exclusions and narrower circumstances where a boat under 6 m may be considered. As of November 2026 a draft revision is under development; a draft is not a replacement for the cited published 2022 edition. This article explains translation discipline, not a formula for deciding vessel safety or certification.
Quick information: retain hull length, displacement, load and crew assumptions; keep the assessed configuration distinct from other model variants; separate stability, buoyancy, flotation and swamping; preserve design-category letters exactly; distinguish maximum total load from passenger count; do not make sea-state, wind or operating promises beyond the source; keep multihull inversion and escape language precise; and check every drawing, test condition and approval status. The objective is for readers in any language to interpret the same documented limitations and design evidence as those reading the original. All numerical and document examples in this guide are fictional teaching cases.
Read the boat evidence, not just the vocabulary
What the source actually covers
The ISO catalogue identifies methods for assessing the stability and buoyancy of intact boats and for considering flotation characteristics where swamping is relevant. It principally concerns human- or mechanically-propelled craft in the stated size range. Some excluded craft types and operations such as towing or lifting need separate consideration. A translator should not expand this scope in a brochure, report or certificate simply because the words ‘small craft’ seem universal.
The document package
A realistic assignment may include test reports, stability calculations, arrangement drawings, loading booklets, compliance statements, inspection forms, model specifications and sales materials. The authoritative technical value may be in a table, while the accompanying prose merely describes it. Collect all source revisions and identify whether the target text is a report, proposed marketing claim, approved manual or evidence summary. Never silently reconcile conflicting inputs.
Why design-category language is delicate
The letters A through D are formal design categories within the applicable assessment and regulatory context. They are not casual rankings of build quality, not a guarantee of unlimited operational safety and not a way for a translator to choose a permitted voyage. A translated passage must preserve the category assigned, the evaluated load and all qualifications accompanying it. If a vessel’s operational guidance depends on additional rules, retain that distinction.
What constitutes a safe translation decision
A good translation maps each proposition to a physical object, condition, measurement or documented decision. It is safe to translate a term more explicitly if that preserves its meaning; it is unsafe to increase the rated load, suggest a more favourable category or remove an exclusion. Check the original calculation, drawing or approved statement rather than looking for a more reassuring adjective.
Limit of this educational guide
The full copyrighted standard is not reproduced here. Neither the translated examples nor an ordinary-language explanation establishes the allowable load for a real boat. Designers, surveyors, assessors and owners must rely on the licensed standard, applicable regulations, current boat documents and competent professional review. The translator’s responsibility is to preserve evidence and query uncertainty.
How to organise a global edition
Start with a stable glossary for vessel geometry, buoyancy, loading and design categories. Preserve the original technical identifiers even when the target alphabet uses different characters. Match source diagrams to captions and tables. Keep factual measurement results separate from interpretive statements. Then have a marine technical reviewer inspect the finished text alongside the complete source package.
Thirty-nine essential small-craft translation decisions
1. Design category A–D
The category designation is a formal recorded assessment outcome tied to the evaluated design and loading. Changing a letter or describing A as universally safe anywhere invents an operational promise.
Keep the literal category and the original qualifying conditions. Verify the signed design assessment and related manual.
The technical distinction is consequential: two grammatically acceptable labels may describe different physical quantities. A reader must be able to trace the target term to the correct drawing, value and condition before acting on the document.
2. Maximum total load
Maximum total load refers to a stated combined load basis, not merely the number of passengers. Translating kilograms as persons can make a boat appear capable of carrying an unsupported weight.
Preserve units and included load components precisely. Compare the loading calculation and builder’s plate.
In a bilingual quality check, test this entry by comparing the translated sentence with the numerical table and relevant figure. If a stronger safety conclusion appears in the target language, the translation has exceeded the evidence.
3. Hull length
Hull length is a defined dimension with a particular measurement convention. A marketing overall length may not be identical to the relevant hull-length measurement.
Keep the source symbol, units and definition tied together. Check dimensioned drawings and cited measurement method.
International readers do not all use the same informal nautical vocabulary. A controlled term plus an original identifier is more dependable than a locally familiar word that obscures the report’s scope or geometry.
4. Length overall
Length overall can be presented differently from hull length in commercial specifications. Replacing one with the other changes applicability and can move the assessment into a wrong scope.
Use distinct target-language terms for each length measure. Compare the stated dimensions with the geometry sheet.
The source’s conditions are part of its meaning. Removing a loading restriction or changing a configuration can invalidate the real-world conclusion even though every remaining word appears correctly translated.
5. Non-sailing craft
The part primarily concerns craft propelled by human or mechanical power within stated scope. Translating all recreational boats as covered would incorrectly include other craft and exclusions.
Keep power and propulsion descriptions in the scope statement. Check the model classification and applicable part.
The technical distinction is consequential: two grammatically acceptable labels may describe different physical quantities. A reader must be able to trace the target term to the correct drawing, value and condition before acting on the document.
6. Intact stability
Intact describes the condition without damage assumed by the relevant evaluation. Rendering it as damaged-vessel stability changes the technical question.
Use an unambiguous technical equivalent and retain the tested condition. Inspect assessment assumptions.
In a bilingual quality check, test this entry by comparing the translated sentence with the numerical table and relevant figure. If a stronger safety conclusion appears in the target language, the translation has exceeded the evidence.
7. Buoyancy
Buoyancy concerns floating behaviour and support, not automatically the same evaluation as stability. A floating boat is not necessarily proven stable under every applicable condition.
Translate the measured or assessed property rather than substituting a general word such as seaworthy. Check buoyancy sections and conclusions.
International readers do not all use the same informal nautical vocabulary. A controlled term plus an original identifier is more dependable than a locally familiar word that obscures the report’s scope or geometry.
8. Stability
Stability concerns how a vessel responds to inclination and relevant disturbances under an evaluated condition. A target text that promises a boat cannot capsize goes beyond typical documented evidence.
Retain physical test names and loading conditions. Compare calculation results and stated limits.
The source’s conditions are part of its meaning. Removing a loading restriction or changing a configuration can invalidate the real-world conclusion even though every remaining word appears correctly translated.
9. Swamping
Swamping describes substantial water entry or inundation in a relevant boat scenario. Do not translate swamped as sunk or as merely wet without contextual support.
Preserve the described condition and its role in flotation assessment. Consult diagrams and test descriptions.
The technical distinction is consequential: two grammatically acceptable labels may describe different physical quantities. A reader must be able to trace the target term to the correct drawing, value and condition before acting on the document.
10. Flotation
Flotation characteristics may be assessed in connection with a swamped condition. Do not substitute dry freeboard or intact buoyancy conclusions for a documented swamped-flotation result.
Keep the test condition and observed position explicit. Check relevant flotation records.
In a bilingual quality check, test this entry by comparing the translated sentence with the numerical table and relevant figure. If a stronger safety conclusion appears in the target language, the translation has exceeded the evidence.
11. Reserve buoyancy
Reserve buoyancy is a technical concept distinct from simple current floating status. An unsupported statement of emergency safety can arise from overconfident wording.
Translate it using the approved engineering context. Confirm the defined quantity or descriptive use.
International readers do not all use the same informal nautical vocabulary. A controlled term plus an original identifier is more dependable than a locally familiar word that obscures the report’s scope or geometry.
12. Freeboard
Freeboard denotes a defined vertical distance whose reference points matter. A mistranslated datum can reverse the meaning of a clearance figure.
Preserve reference geometry and units. Check drawings and measurement tables.
The source’s conditions are part of its meaning. Removing a loading restriction or changing a configuration can invalidate the real-world conclusion even though every remaining word appears correctly translated.
13. Heel angle
Heel expresses transverse inclination in a defined assessment context. Confusing heel with trim changes the axis of motion.
Use distinct terms with angle sign and units retained. Cross-check sketches and plotting labels.
The technical distinction is consequential: two grammatically acceptable labels may describe different physical quantities. A reader must be able to trace the target term to the correct drawing, value and condition before acting on the document.
14. Trim
Trim describes fore-aft attitude rather than a lateral heel. A target caption that confuses the two can misplace the loading condition.
Keep bow and stern references explicit. Check hydrostatic or inclination diagrams.
In a bilingual quality check, test this entry by comparing the translated sentence with the numerical table and relevant figure. If a stronger safety conclusion appears in the target language, the translation has exceeded the evidence.
15. Righting moment
The concept concerns a restoring tendency or moment under defined conditions. Do not turn a calculated moment into a universal prediction about real sea events.
Retain the relation to the assessed angle and state. Check calculation axes and units.
International readers do not all use the same informal nautical vocabulary. A controlled term plus an original identifier is more dependable than a locally familiar word that obscures the report’s scope or geometry.
16. Righting arm
A righting-arm value and righting moment are related but not the same quantity. Swapping their labels misstates magnitude and dimension.
Keep the correct physical quantity and units. Review the plotted curve legend.
The source’s conditions are part of its meaning. Removing a loading restriction or changing a configuration can invalidate the real-world conclusion even though every remaining word appears correctly translated.
17. Centre of gravity
The centre of gravity affects assessed loading and stability. Assuming every optional accessory is accounted for may be false.
Preserve its location and applicable condition. Review mass properties and drawings.
The technical distinction is consequential: two grammatically acceptable labels may describe different physical quantities. A reader must be able to trace the target term to the correct drawing, value and condition before acting on the document.
18. Centre of buoyancy
The centre of buoyancy is a different physical point from the centre of gravity. Translating both as balance point erases essential distinctions.
Use separate standard technical terms. Inspect the hydrostatic model notes.
In a bilingual quality check, test this entry by comparing the translated sentence with the numerical table and relevant figure. If a stronger safety conclusion appears in the target language, the translation has exceeded the evidence.
19. Displacement
Displacement in boat calculations is not simply the engine’s swept volume. A cross-domain false friend can turn a vessel mass or volume context into motor specification.
Keep mass or volume meaning and units explicit. Check the data column definition.
International readers do not all use the same informal nautical vocabulary. A controlled term plus an original identifier is more dependable than a locally familiar word that obscures the report’s scope or geometry.
20. Light craft mass
A light-craft mass condition differs from maximum loaded mass. A translation that omits the loading basis makes two results appear comparable when they are not.
Preserve the exact mass condition attached to each result. Consult the load case table.
The source’s conditions are part of its meaning. Removing a loading restriction or changing a configuration can invalidate the real-world conclusion even though every remaining word appears correctly translated.
21. Crew distribution
The position of persons on board can be part of an assessment condition. Do not reduce a positional test to a total headcount if location matters.
Keep distribution instructions and figures linked. Review source diagrams.
The technical distinction is consequential: two grammatically acceptable labels may describe different physical quantities. A reader must be able to trace the target term to the correct drawing, value and condition before acting on the document.
22. Passenger capacity
Passenger count is not necessarily equivalent to load mass or design category. An added passenger in translated marketing text could contradict the documented assessment.
Retain the original count and separately stated mass limits. Check builder documentation.
In a bilingual quality check, test this entry by comparing the translated sentence with the numerical table and relevant figure. If a stronger safety conclusion appears in the target language, the translation has exceeded the evidence.
23. Fuel and water load
Fuel and fresh-water states may affect a defined loading scenario. Replacing a partial tank condition with full tanks changes the model.
Preserve tank type, capacity and fill assumption. Check load-case notes.
International readers do not all use the same informal nautical vocabulary. A controlled term plus an original identifier is more dependable than a locally familiar word that obscures the report’s scope or geometry.
24. Portable equipment
Portable items may be included or excluded from evaluated total loads according to definitions. Omitting equipment from a translated load list can inflate apparent remaining capacity.
Retain named categories and inclusion rules. Compare owner’s manual and calculation sheet.
The source’s conditions are part of its meaning. Removing a loading restriction or changing a configuration can invalidate the real-world conclusion even though every remaining word appears correctly translated.
25. Open cockpit
An open area may have flooding and drainage implications under the assumed design. Calling a space enclosed when it is open can misrepresent the assessment.
Preserve space type and openings. Review arrangement drawings.
The technical distinction is consequential: two grammatically acceptable labels may describe different physical quantities. A reader must be able to trace the target term to the correct drawing, value and condition before acting on the document.
26. Quick-draining recess
Quick-draining has a specific design context, not a general promise that water instantly disappears. Do not translate it into completely waterproof or flood-proof.
Keep the descriptive mechanism and limitations. Check relevant geometry and drainage references.
In a bilingual quality check, test this entry by comparing the translated sentence with the numerical table and relevant figure. If a stronger safety conclusion appears in the target language, the translation has exceeded the evidence.
27. Decked craft
Decking condition is relevant to the scope of some smaller craft assessments. Describing an un-decked boat as decked changes apparent eligibility.
Keep the source structural category. Inspect design plan.
International readers do not all use the same informal nautical vocabulary. A controlled term plus an original identifier is more dependable than a locally familiar word that obscures the report’s scope or geometry.
28. Multihull
Multihull design can introduce assessment questions differing from monohulls. A single-hull analogy may obscure inversion or escape considerations.
Preserve the vessel configuration and relevant report section. Check drawings and referenced criteria.
The source’s conditions are part of its meaning. Removing a loading restriction or changing a configuration can invalidate the real-world conclusion even though every remaining word appears correctly translated.
29. Inversion
Inversion concerns a vessel turning over and potentially remaining inverted. Do not soften it to tilting if the source concerns capsizing or inverted flotation.
Keep the event and relevant escape scenario explicit. Verify the assessment context.
The technical distinction is consequential: two grammatically acceptable labels may describe different physical quantities. A reader must be able to trace the target term to the correct drawing, value and condition before acting on the document.
30. Means of escape
Escape language refers to defined access or egress arrangements, especially important in particular multihull contexts. Replacing an emergency exit with an ordinary door is not necessarily equivalent.
Keep location, availability and conditions attached to the description. Match plan labels and approved report.
In a bilingual quality check, test this entry by comparing the translated sentence with the numerical table and relevant figure. If a stronger safety conclusion appears in the target language, the translation has exceeded the evidence.
31. Maximum recommended engine power
Power information may be separate from the stability category and maximum loading statement. Do not infer that more engine power is allowed because a stability result is favourable.
Preserve the distinct limit and source of authority. Check the propulsion assessment and builder specifications.
International readers do not all use the same informal nautical vocabulary. A controlled term plus an original identifier is more dependable than a locally familiar word that obscures the report’s scope or geometry.
32. Sea conditions
A general statement about waves or wind requires its own evidenced and regulatory context. Avoid inventing sea-state or geographical permission from category letters alone.
Translate source qualifications, not popular simplifications. Review the approved manual and applicable definitions.
The source’s conditions are part of its meaning. Removing a loading restriction or changing a configuration can invalidate the real-world conclusion even though every remaining word appears correctly translated.
33. Operational limitation
A design assessment and an operational limitation serve different purposes. A translator must not remove an owner-manual warning because a design category appears elsewhere.
Retain all warnings, conditions and exceptions. Compare the safety notice and regulatory documentation.
The technical distinction is consequential: two grammatically acceptable labels may describe different physical quantities. A reader must be able to trace the target term to the correct drawing, value and condition before acting on the document.
34. Test vessel configuration
A test or calculation may address one hull, fitted equipment and build revision. A sister boat with different equipment may not have identical documented evidence.
Preserve model and revision identifiers. Check build configuration.
In a bilingual quality check, test this entry by comparing the translated sentence with the numerical table and relevant figure. If a stronger safety conclusion appears in the target language, the translation has exceeded the evidence.
35. Draft revision
An ISO draft may be under development while the older published edition remains applicable. Describing a draft as an already published requirement creates a false citation.
State published versus draft status explicitly. Verify the ISO catalogue at the time of use.
International readers do not all use the same informal nautical vocabulary. A controlled term plus an original identifier is more dependable than a locally familiar word that obscures the report’s scope or geometry.
36. Exclusions
Certain craft and operations are expressly outside the part’s described scope. Suppressing exclusions makes the article seem to apply to craft it does not cover.
Translate excluded categories clearly and completely. Compare the official catalogue scope.
The source’s conditions are part of its meaning. Removing a loading restriction or changing a configuration can invalidate the real-world conclusion even though every remaining word appears correctly translated.
37. Towing and lifting
Operational loads from towing, fishing, dredging or lifting are not automatically evaluated by this intact-stability part. A claim of assessed lifting safety based solely on a general stability report would be misleading.
Keep additional assessment needs separate. Review the project’s operation-specific evidence.
The technical distinction is consequential: two grammatically acceptable labels may describe different physical quantities. A reader must be able to trace the target term to the correct drawing, value and condition before acting on the document.
38. Unit conversions
Mass, length and angles may appear in SI or other units. An unsourced conversion or wrong thousands separator can change a safety-relevant numerical value.
Preserve source and permitted conversions with precision and units. Independently recalculate conversions if authorised.
In a bilingual quality check, test this entry by comparing the translated sentence with the numerical table and relevant figure. If a stronger safety conclusion appears in the target language, the translation has exceeded the evidence.
39. Conditional approval
A document may identify approval subject to specific unresolved requirements. Calling conditional status final approval removes the restriction.
Retain conditions, responsible role and date. Check signed decision and issue history.
International readers do not all use the same informal nautical vocabulary. A controlled term plus an original identifier is more dependable than a locally familiar word that obscures the report’s scope or geometry.
Twenty fictional worked examples
1. Two length figures
A fictional sales brochure gives overall length 7.2 m while the technical report lists a different hull length. Wrong: replace both with 7.2 m for consistency.
Correct: use the source’s separate labels and values without guessing. Check dimension drawings and the measurement definitions. A useful teaching question is whether the target-language reader could reproduce the correct interpretation by returning to the original calculation rather than trusting a confident paraphrase.
2. Category mentioned without load
A paragraph quotes category C but omits the accompanying maximum load shown in a table. Wrong: treat category C as an unqualified capability.
Correct: preserve the specific category and load relationship present in the document. Check signed report and builder plate. Keep a documented query for this problem. The translator cannot resolve physical design uncertainties by choosing the synonym that reads most smoothly.
3. Seven persons or 700 kg
A sample chart lists seven people in one field and 700 kg total in another. Wrong: translate both as passenger capacity.
Correct: keep people and mass as separate measures. Check load components and stated conditions. The review must inspect both the sentence and its visual or numeric context. Translation errors often arise when charts, captions and notes are separated.
4. A swamping test
A fictional observation says the boat floated under a defined swamped condition. Wrong: ‘boat cannot sink under any circumstances’.
Correct: reproduce the bounded observation and test condition. Check the test report’s purpose and limitations. The final test is decision equivalence: would an owner, surveyor or manufacturer infer exactly the same capability and qualification in both languages?
5. Heel and trim
A diagram has 9 degrees of heel and a separate fore-aft trim note. Wrong: label both as tilt without directions.
Correct: preserve transverse and longitudinal attitude terms. Check axis arrows and chart legends. A useful teaching question is whether the target-language reader could reproduce the correct interpretation by returning to the original calculation rather than trusting a confident paraphrase.
6. A multihull escape plan
An appendix specifies an escape route for an inverted multihull. Wrong: translate it as ordinary passenger boarding.
Correct: retain the inverted-vessel context and route. Check the relevant plan and approved wording. Keep a documented query for this problem. The translator cannot resolve physical design uncertainties by choosing the synonym that reads most smoothly.
7. Draft standard confusion
An email references an upcoming ISO/DIS revision. Wrong: change the 2022 published citation to the draft.
Correct: identify the draft as under development and retain the approved source edition. Check official catalogue. The review must inspect both the sentence and its visual or numeric context. Translation errors often arise when charts, captions and notes are separated.
8. Towing a disabled vessel
A boat owner asks whether a stability assessment covers towing loads. Wrong: say yes on the strength of a design category alone.
Correct: preserve the absence of evidence for that operation. Request operation-specific professional assessment. The final test is decision equivalence: would an owner, surveyor or manufacturer infer exactly the same capability and qualification in both languages?
9. Omitted tank condition
A table describes a fuel tank partly filled during a tested load case. Wrong: rewrite it as tank full.
Correct: keep the exact stated tank condition. Check calculation case identifier. A useful teaching question is whether the target-language reader could reproduce the correct interpretation by returning to the original calculation rather than trusting a confident paraphrase.
10. Category letter transcription
A PDF scanned poorly and B resembles an 8. Wrong: select the apparent character from OCR without further check.
Correct: query the approved original and cross-check the report title. Do not guess a formal category. Keep a documented query for this problem. The translator cannot resolve physical design uncertainties by choosing the synonym that reads most smoothly.
11. Loss of a warning
A multilingual manual draft drops a maximum-load notice beside a drawing. Wrong: publish the text as complete because body paragraphs remain.
Correct: translate and position the warning with its source context. Compare rendered pages side by side. The review must inspect both the sentence and its visual or numeric context. Translation errors often arise when charts, captions and notes are separated.
12. Righting-arm units
An engineering table uses metres for an arm and newton-metres for a moment. Wrong: assign the same unit to both.
Correct: retain dimensional differences. Compare units to equation and plot. The final test is decision equivalence: would an owner, surveyor or manufacturer infer exactly the same capability and qualification in both languages?
13. Hull model changed
A dealer adds a new optional roof and claims the former test covers the boat. Wrong: say the modified design was tested.
Correct: state the exact model and configuration from the approved record. Query designer about changes. A useful teaching question is whether the target-language reader could reproduce the correct interpretation by returning to the original calculation rather than trusting a confident paraphrase.
14. Measured versus modelled
A report includes calculated results and separately observed test results. Wrong: call every number a sea-trial measurement.
Correct: preserve calculation versus observation labels. Compare method descriptions. Keep a documented query for this problem. The translator cannot resolve physical design uncertainties by choosing the synonym that reads most smoothly.
15. The day-month trap
A certificate uses 05/07/2026 with no declared date convention. Wrong: silently choose one international reading.
Correct: retain the original and query the date format. Use document-control metadata. The review must inspect both the sentence and its visual or numeric context. Translation errors often arise when charts, captions and notes are separated.
16. Marketing says ocean-ready
The source only identifies a design category under specific load assumptions. Wrong: transform it into worldwide unrestricted operation.
Correct: restrict claims to the evaluated scope. Seek technical and legal sign-off. The final test is decision equivalence: would an owner, surveyor or manufacturer infer exactly the same capability and qualification in both languages?
17. Out-of-scope inflatable
A tender describes a rigid-inflatable boat subject to another standard series. Wrong: imply ISO 12217-1 directly covers all such craft.
Correct: keep the exclusion and referenced route distinct. Check vessel type and regulatory requirements. A useful teaching question is whether the target-language reader could reproduce the correct interpretation by returning to the original calculation rather than trusting a confident paraphrase.
18. Unapproved certificate
A draft assessment sheet has an unsigned approval field. Wrong: translate ‘approved’ because a logo is present.
Correct: preserve draft or pending status. Verify formal signature and version. Keep a documented query for this problem. The translator cannot resolve physical design uncertainties by choosing the synonym that reads most smoothly.
19. Changing a mass unit
An exporter converts tonnes to kilograms but accidentally changes the numerical magnitude. Wrong: publish the plausible-looking converted value.
Correct: preserve units or verify a documented conversion independently. Reconcile with original calculation. The review must inspect both the sentence and its visual or numeric context. Translation errors often arise when charts, captions and notes are separated.
20. No one checked the diagram
A figure labels starboard and port positions while the text is translated independently. Wrong: mirror left and right for a target-language page layout.
Correct: preserve actual vessel orientation in figures and captions. Verify the final page visually. The final test is decision equivalence: would an owner, surveyor or manufacturer infer exactly the same capability and qualification in both languages?
A twelve-stage controlled review workflow
Stage 1
Confirm the original controlled issue, design revision and vessel model. Obtain referenced sketches and calculations rather than working from one exported page.
Stage 2
Define the intended audience, requested language pair and legal or contractual use of the translated document.
Stage 3
Verify the cited standard and whether it is published or merely under development; preserve the historic citation in source records.
Stage 4
Lock all vessel identifiers, categories, model suffixes, drawings, serial numbers and load-case codes.
Stage 5
Create a marine glossary distinguishing hull length, overall length, heel, trim, stability, buoyancy, flotation and swamping.
Stage 6
Capture every table, graph axis, diagram, warning symbol, footnote and caption in the translation scope.
Stage 7
Translate unit labels and loading assumptions together. Record conversions explicitly when authorised.
Stage 8
Distinguish observed tests from modelled calculations and approved findings from proposed claims.
Stage 9
Check applicability and explicit exclusions before writing any summary about vessel type or operation.
Stage 10
Use a marine technical reviewer for design, load and safety language. A general language editor alone is insufficient.
Stage 11
Perform a final bilingual visual comparison including port/starboard orientation and drawing labels.
Stage 12
Preserve the glossary, resolved queries, reviewer sign-off and final files for controlled traceability.
Frequently asked questions
What does ISO 12217-1:2022 cover?
It addresses specified stability and buoyancy assessment of mainly non-sailing intact small craft in its scope. It does not automatically evaluate every craft or special operation.
Can I translate design categories A to D into descriptive grades?
Retain the formal letter. Explain it only with properly sourced definitions and the specific evaluated conditions; avoid invented operating promises.
What is different between buoyancy and stability?
They are related physical concepts but not synonyms. A boat’s flotation result cannot stand in for every stability evaluation.
Should I convert hull length to length overall?
No. Preserve the dimension defined in the source and its measurement convention.
Does a higher category allow unrestricted voyages?
No such unlimited permission should be inferred by a translator. Use the document’s actual category, conditions and applicable regulatory guidance.
Can a designer’s calculation be translated as a sea trial?
No. Calculated and observed evidence must retain their respective labels.
What if the ISO edition changes next month?
A draft revision is not the published edition. Confirm status when preparing a new document, but do not rewrite historic citations without controlled authorisation.
How should units be handled?
Retain values, precision, symbols and reference conditions. Perform conversions only when requested and independently checked.
Can marketing language be strengthened?
Not if it increases an assessed capability, removes a warning or invents proof. Flag unsupported claims for review.
Who should review the target text?
A technical marine professional should check the evidence and safety meaning, followed by target-language quality review.
