A large yacht can be bought with cash or financed against the hull itself. Understanding how the marine mortgage is priced, secured and governed decides whether borrowing is a discipline or a trap.
You have agreed a price on a €40m yacht and can, in theory, wire the full sum. Yet your family office is asking whether that is the right use of liquidity, and three lenders have returned three very different term sheets — different loan-to-value, different margins over benchmark, different covenants on where the vessel may trade. The numbers look comparable until you read the fine print, and the fine print is where superyacht finance is won or lost.
A marine mortgage is a secured loan in which the yacht itself is the principal collateral. It behaves less like a residential mortgage and more like a specialised asset-finance facility, because the asset moves internationally, depreciates on a known curve and carries running costs a lender must factor into the risk. The two dominant forms are the straightforward mortgage — the bank lends, takes security over the hull, and is repaid over a term — and the finance lease, in which a leasing company owns the vessel and the beneficial user pays to use it, often for VAT and structuring reasons rather than pure funding need.
Loan-to-value is the first number that matters. On a modern, surveyed yacht from an established builder, lenders typically advance 50–70 per cent of value, occasionally higher for the strongest borrowers on the newest hulls, and less on older or more esoteric vessels. Terms commonly run five to ten years, sometimes with a balloon repayment at the end that assumes refinancing or sale. The borrower funds the balance in cash, so financing rarely removes the need for real equity — it changes how much, and when.
Marine mortgage rates are quoted as a margin over a reference rate, not as a single headline figure, and the two components move independently. The reference is a benchmark such as SOFR for US-dollar lending or EURIBOR for euro facilities; the margin is the lender's charge for the specific risk of the specific deal. Add the two and you have the all-in cost, which is why a yacht loan priced today can carry a materially different rate from one priced eighteen months ago even at an identical margin.
The margin itself is negotiated against the profile of the borrower and the asset. It widens with age of vessel, thinness of the resale market for that type, intended charter or commercial use, and any weakness in the borrower's wider balance sheet; it narrows for a blue-chip private-bank client borrowing conservatively against a new build. The figures below are indicative ranges, not quotes, and reset with the rate cycle.
| Structure | Typical LTV | Indicative margin over benchmark | Typical term |
|---|---|---|---|
| Private-bank mortgage (existing client) | 60–70% | 1.5–3.0% | 5–10 yrs |
| Specialist marine lender | 50–65% | 2.5–4.5% | 5–7 yrs |
| Finance lease (VAT / structuring led) | Varies | Lease rental basis | 3–7 yrs |
These bands illustrate the shape of the market rather than any individual offer; a single strong relationship can beat them, and a difficult asset can fall outside them entirely.
Two broad camps provide superyacht finance, and choosing between them is as consequential as choosing the rate. Their appetites, service and covenants differ sharply, and the cheapest quote is frequently not from the party you will most want alongside you when circumstances change.
The practical test is not who is cheapest on day one but who understands the asset, will act reasonably on a covenant breach, and will still be lending against yachts through the next downturn.
The security behind a marine mortgage is inseparable from where the yacht is registered, because the mortgage is recorded against the vessel in a national ship registry and its enforceability depends on that registry's law. This is why lenders care intensely about the flag. A yacht flagged in an established maritime register — the sort used by the majority of large yachts — gives the lender a well-tested legal route to enforce and, if it must, arrest and sell the vessel to recover the debt. An obscure or poorly regarded flag weakens that route and is reflected in appetite and margin.
Registration also shapes the mechanics. The mortgage is a registered charge ranking ahead of most subsequent claims; the lender will require its interest noted on the registry and will control any change of flag, because re-flagging can disturb the security. For the borrower this means the choice of registry — often driven by tax, crewing rules and cruising permissions — must be made with the financing in mind from the outset, not bolted on afterwards. A flag that suits the owner's cruising plans but unsettles the lender can quietly cost basis points or scupper a deal.
The covenants attached to a marine mortgage govern the yacht's life for the length of the loan, and they are more intrusive than most first-time borrowers expect. They exist because the collateral is mobile, perishable and exposed to the sea, so the lender writes conditions designed to keep the asset intact and insured throughout the term.
Breaching a covenant — letting cover lapse, cruising off-limits, chartering without consent — can technically default the loan even when payments are current. Reading these clauses before signing is not administrative caution; it is the difference between owning the yacht and merely holding it at the lender's pleasure.
For an owner who can pay outright, the question is never affordability but efficiency, and the honest answer depends on what else the money could do. Financing a yacht makes sense when the borrower's capital earns more, after tax, than the all-in cost of the loan — when liquidity is worth keeping deployed rather than sunk into a depreciating asset, or when a leasing structure delivers a VAT or cruising advantage that outweighs its cost. It also preserves flexibility: cash retained is cash available for opportunities, calls and the yacht's own considerable running costs.
Cash wins when rates are high relative to expected returns, when the borrower values simplicity and privacy over leverage, or when covenants would constrain how the yacht is used in ways the owner will not accept. Many UHNW buyers land in the middle — a conservative mortgage on part of the value, cash for the rest — capturing some efficiency without ceding control. None of the above is financial, tax or legal advice; figures are indicative and every structure must be tested against your own circumstances with qualified advisers. The right answer is the one that survives that scrutiny, not the one with the lowest headline rate.
We introduce owners and family offices to vetted private banks, specialist marine lenders and leasing houses through our Marketplace network, under NDA, and read every term sheet against the same standard — LTV, margin over benchmark, flag, covenants and trading limits — so you compare like with like. Give us the vessel, the flag and the outcome you want, and we help you negotiate one clear, all-in cost of finance rather than a headline rate.

On a modern, surveyed yacht from an established builder, lenders typically advance 50–70% of value, with the strongest private-bank clients occasionally reaching higher on the newest hulls. Older or unusual vessels attract lower LTV. You fund the balance in cash, so financing reduces rather than removes the equity you must commit.
The rate is a margin over a benchmark such as SOFR or EURIBOR, not a single fixed number. The benchmark moves with the rate cycle; the margin reflects your credit, the vessel's age and resale market, and any charter use. Add the two for the all-in cost, which is why identical margins can price very differently over time.
The mortgage is registered against the vessel in a national ship registry, so its enforceability depends on that registry's law. An established maritime flag gives the lender a tested route to enforce and, if needed, arrest and sell the yacht. A weak or obscure flag undermines the security and is reflected in reduced appetite and wider margins.
Expect requirements for a satisfactory survey, comprehensive hull-and-machinery and liability insurance with the lender's interest noted, trading limits excluding sanctioned or war-risk waters, and restrictions on commercial chartering. Some borrowers also face financial covenants on net worth or liquidity. Breaching any of these can default the loan even when payments are fully up to date.
Finance makes sense when your retained capital earns more, after tax, than the all-in loan cost, or when a lease delivers a VAT or cruising advantage. Cash wins when rates are high relative to returns, or when covenants would constrain use unacceptably. Many owners blend the two. This is not advice; test every structure with qualified advisers.
