Yacht insurance by flag: what is compulsory and what the market requires
Little insurance is compulsory by flag for most yachts; lenders and charterers impose the rest. What each flag requires, set out here with sources.
Yacht insurance has two layers: the certificates a flag makes compulsory, and the cover a lender, a charter contract or ordinary prudence requires on top. The compulsory layer is narrower than most owners expect. A small number of international certificates become compulsory once a flag has taken them on; almost everything else an owner carries is required by the market rather than by the flag itself. WhichFlagToFly sets out the compulsory layer with sources, then the market layer on top of it.

A flag that has taken on the Nairobi International Convention on the Removal of Wrecks requires larger vessels flying it to carry a wreck-removal insurance certificate, evidencing cover for the cost of removing a sunk or disabled vessel. Not every register in this comparison has taken the Convention on; where a flag has not, the position below says so.

Does passenger-liability law reach a yacht carrying a handful of guests?Link to this section
The Athens Convention and its 2002 Protocol govern carrier liability for the carriage of passengers by sea, and a flag that has taken on the 2002 Protocol applies it to vessels flying it. Whether the framework reaches a charter yacht carrying a small number of guests depends on how each flag applies the Protocol, and the positions below state what each register publishes rather than a general rule.

How much does yacht insurance cost?Link to this section
A premium is set against the yacht's agreed value, its use, its cruising area and its claims record, so no single rate describes the market. No market fee band for yacht insurance is published in the fact corpus behind this site, and none is invented here. Ask a broker to price the rest against the yacht itself.
How does chartering change what you need?Link to this section
A yacht that charters commercially typically needs cover that goes well beyond the compulsory certificates above, because a chartering contract, a management agreement or the coastal state where charter begins can each impose their own requirements. See chartering your yacht commercially and ISM, ISPS and MLC for yachts for how those obligations interact with a yacht's flag.
How do you get cover in place?Link to this section
This page sets out what is compulsory and what independent reporting says the market charges; it does not sell, arrange or distribute insurance, and nothing here is insurance advice. A specialist marine insurance broker can price cover against a specific yacht, its flag, its use and its cruising area.
