A yacht undergoes a major refit that adds an extended swim platform, increases beam slightly, and converts a former crew cabin into additional guest space. As Master, what should you confirm before the vessel returns to commercial operation?

A. MAJOR REFIT — CONFIRMING RE-SURVEY/RE-CODING NEEDS: Significant structural or layout changes can affect a yacht's measured tonnage, stability, fire zone arrangement, and crew/guest accommodation balance — all of which are foundational to its existing Code Compliance Certificate. BEFORE RETURNING TO COMMERCIAL OPERATION, THE MASTER SHOULD CONFIRM: (1) Whether the refit changes measured GT (e.g. extended swim platform, beam increase) in a way that could move the vessel across a Code tonnage threshold (200GT, 500GT) — this could trigger entirely different crew accommodation equivalence or structural fire protection requirements; (2) Whether the refit has been reviewed and approved by the classification society/flag state BEFORE the work was carried out, not just inspected afterwards — unauthorised structural changes can invalidate the existing CCC; (3) Whether converting a crew cabin to guest space affects the vessel's crew accommodation compliance for the REMAINING crew (e.g. if remaining cabins now need to accommodate crew previously housed in the converted space) — this is a real, practical equivalence compliance question, not just a layout preference; (4) Whether updated stability information reflecting the as-refitted condition has been produced and approved, since the previous approved stability information may no longer accurately describe the vessel. THE GENERAL PRINCIPLE: any refit with the potential to affect tonnage, stability, fire protection or accommodation compliance should be planned WITH class/flag state involvement from the design stage, with formal re-survey/certificate endorsement completed before resuming guest-carrying commercial operation — discovering a problem only when a surveyor objects after the fact is a planning failure.

B. Refits only require re-survey if the yacht's name or external paint scheme changes; internal layout and minor structural changes have no bearing on existing certification.

C. Converting a crew cabin to guest space is purely an interior design decision with no compliance implications, since crew accommodation standards apply only to the original as-built configuration.

D. Re-survey is only required if the refit is cosmetic; any change described by the yard as "structural" is automatically pre-approved regardless of class/flag state review.

A. SURVEY CYCLE UNDER THE CODE — ANNUAL / INTERMEDIATE / RENEWAL: Coded yachts are subject to a periodic survey regime broadly analogous to SOLAS-style survey cycles, scaled to the Code's certification framework: (1) ANNUAL SURVEY — a routine confirmation that the vessel and its equipment remain in the condition certified, conducted by the classification society/Recognised Organisation on the flag state's behalf; (2) INTERMEDIATE SURVEY — a more detailed mid-cycle survey (typically around the midpoint of the certificate's validity period) covering specific systems/equipment in more depth than the annual survey; (3) RENEWAL SURVEY — the full survey conducted before the Code Compliance Certificate's validity period expires, required to renew the certificate for a further period; failure to complete it in time means the certificate lapses. CONSEQUENCES OF A MISSED OR OVERDUE SURVEY: (1) The Code Compliance Certificate (and other certificates tied to the survey cycle) can become invalid, meaning the vessel is technically uncoded and should not operate commercially with guests until the survey is completed and the certificate reinstated/renewed; (2) Port State Control inspections check certificate validity as standard practice — an expired or lapsed certificate is a serious deficiency that can lead to detention; (3) Insurance cover is likely to be affected if the vessel was operating commercially with an invalid certificate at the time of an incident. CREW/OFFICER RESPONSIBILITY: tracking survey due dates is a standing administrative duty (usually led by the Master/Chief Officer with company support), not something to discover only when a surveyor or PSC officer raises it.

B. Annual, intermediate and renewal surveys are interchangeable terms for the same inspection, repeated at the surveyor's discretion with no fixed cycle or consequence for being overdue.

C. Missing an intermediate survey has no consequence as long as the annual and renewal surveys are completed on schedule.

D. Survey cycles under the Code apply only to the hull and machinery; certificates relating to crew, manning and accommodation never require periodic re-survey.

A. MASTER CERTIFICATE TONNAGE BANDS — WHY THE RIGHT CoC MATTERS: Manning and certification requirements under the Code are tied to tonnage bands, broadly: Master (Yachts) <200GT, Master/OOW (Yachts) <500GT, and Master/OOW (Yachts) Unlimited — each certificate of competency authorises command/watchkeeping only up to the tonnage (and any other) limit stated on that certificate. A Master holding only a <200GT certificate is NOT qualified to take command of a 480GT yacht — doing so would mean the vessel is operating without a properly certificated Master, a serious compliance failure exposing the individual, the vessel, and the management company. CORRECT PATHWAY: the candidate would need to complete the further training/sea time/examination requirements to upgrade to the Master <500GT (or higher) certificate before taking command of a vessel in that tonnage band — this is not a formality that can be deferred "until there's time," since the certificate must be held and valid AT THE TIME of taking command, matched to the vessel's actual measured GT. PRACTICAL POINT: this is exactly the kind of certificate-tonnage mismatch that Port State Control and flag-state inspections specifically check, and is also why understanding the Code's tonnage bands (already covered in the fundamentals module of this same content area) is directly relevant to an individual's own career planning, not just abstract regulatory knowledge.

B. A Master <200GT certificate authorises command of any coded yacht regardless of tonnage, since the Code does not tie command authority to specific GT bands.

C. Certificate tonnage limits are advisory only; an experienced Master may take command of a larger yacht informally provided the owner is satisfied with their experience.

D. Certificate upgrades between tonnage bands can be completed informally after taking command, provided the upgrade is finalised within the first year.
