On paper, changing management company takes two lines: one termination, one signature. In practice, a handover runs on four parallel tracks — contract, flag, insurance, data — each with its own timeline. Sequenced badly, it produces exactly what the owner set out to avoid: a certificate that lapses, cover extinguished without anyone deciding it, incomplete records. One scope note: DOC, SMC and CSR are statutory for yachts on a commercial registry or in voluntary ISM compliance; for a purely private yacht they are a matter of contract and good practice.
Notice: reread the contract before writing the letter
The market-standard contract for yacht management remains BIMCO’s SHIPMAN, 2024 edition. Clause 30(a) keeps the agreement running until terminated by written notice, with termination effective on the later of two dates: the minimum period agreed in Box 19, or two months from receipt of the notice. Two months is only a default, though, not a norm: Box 19 can extend it, and bespoke contracts often depart from the form. The “three to six months” figures in circulation have no general contractual basis: the only reliable rule is your own agreement.
Two clauses deserve careful reading before the notice goes out. First, clause 31(h): unless the agreement is terminated for the manager’s default, the annual fee remains payable for the number of months stated in Box 20 after termination — 90 days by default if the box is blank. For a quarter, the owner will therefore be paying two managers at once: that overlap cost should be budgeted from the start. Second, clause 18, new in 2024 and drafted with sanctions in mind: a change of control must be notified at least 15 days in advance, and a change of flag or of control gives each party a right to terminate on at least one month’s notice (clauses 31(e) and (f)).
The SMC does not follow the vessel: how DOC/SMC works
The most common mistake is believing the yacht “keeps” its ISM certificates when the manager changes. The opposite is true: the vessel’s Safety Management Certificate is legally anchored to its Company’s Document of Compliance. The Marshall Islands registry puts it unambiguously: withdrawal of the DOC invalidates the SMCs of every vessel attached to it (MN 2-011-13, §11.3). Changing Company means restarting the certification chain.
The mechanics that registry describes are representative of major-flag practice. When a Company takes responsibility for a vessel new to it, an interim SMC valid for no more than 6 months may be issued, subject to conditions verified by the recognised organisation: a relevant DOC (even interim), an SMS covering the essential elements of the ISM Code, master and senior officers familiarised with the system, operational instructions before the first voyage, an internal audit within 3 months. The SMS must be fully implemented on board during those six months (case-by-case extensions, up to six more). On the manager’s side, an interim DOC is valid for at most 12 months, the full-term DOC five years with annual verification. A pre-transition ISM/ISPS audit confirms the file will stand up in front of the flag’s auditor.
The Cayman flag adds two reminders. Its Yachtmaster’s Handbook triggers the interim ISPS assessment “on initial registration or change of management”: a change of manager also reactivates security certification (interim ISSC up to six months). And commercial yachts under 500 GT must keep a “mini ISM” on board — the system transfer also concerns units below the statutory threshold. Finally, for yachts in trade of 500 GT and above, the Continuous Synopsis Record (SOLAS XI-1/5) traces owner, flag, name, class and ISM Company for the vessel’s whole life: every change of Company requires an amendment form filed with the Administration, with all previous versions kept on board — routinely checked by Port State Control.
Insurers: the silent switch
This is the most dangerous track because it gives no warning. The International Hull Clauses provide in clause 14 (“Management”) that, unless underwriters agree otherwise in writing, the hull policy terminates automatically upon transfer of the vessel to new management. Superyacht policies often use bespoke wordings and the clause number varies, but the principle is standard: switching without the hull underwriters’ prior written agreement can extinguish cover on the day. On the P&I side, Gard’s Rule 25.2.f makes cover cease automatically when new managers are appointed, unless the club agrees — the manager’s identity, crewing and technical management included, is material risk information.
In practice, the P&I entry in the incoming manager’s name is confirmed before the switch date, hull policies are endorsed or reissued, and claims open under the outgoing manager are formally transferred. SHIPMAN also organises the exit: the outgoing manager must be removed from the owner’s policies as joint assured and, where reasonably possible, released from premiums and calls for the contract period. Our flag and insurance service coordinates this sequence with brokers and clubs.
Data and accounts: what belongs to the owner
SHIPMAN 2024 settles the question of documentary ownership: clause 22 defines all accounts, documents and information relating to the vessel, electronic data included, as “Vessel Information” — the owner’s property. On termination, the outgoing manager hands it back on request: originals where possible, otherwise certified copies, electronic data in an agreed format; the manager may retain copies. A commonly used perimeter covers four blocks: technical (class, surveys, dry-dockings, machinery history, PMS and outstanding work), safety management (SMS manuals, drills, internal audits, non-conformities), crew records, and regulatory-commercial (SMC, DOC, ISPS, MLC, P&I entry, hull policies, PSC history). The inventory is drawn up jointly before the switch: it is what prevents missing data from surfacing six months later, at the first audit.
Timing: aim for the yard period — without forgetting the crew
In the Mediterranean, most refits and winter lay-ups concentrate between October and April: the winter yard period is the natural window to switch management without touching the owner’s programme. Typical sequence: notice at the end of the season, preparation in parallel — incoming manager’s certification, insurers’ agreements, documentary inventory — and the effective switch alongside, never mid-season. That leaves the crew, deliberately outside this guide’s scope: employment agreements are not “transferred”, they are reissued, and seafarers’ protections can quietly erode. Dedicated analysis: crew contracts and the management handover.
A successful handover is invisible: no break in certification, insurers on board before the switch, data handed back complete, a vessel resuming its programme as if nothing had happened. That requires treating the operation as a project — four tracks, one timeline, one accountable lead — and choosing an incoming manager who has run the sequence before. It is the kind of transition our yacht management service is built to absorb, from notice to first audit.
