How Much Does It Cost to Keep a Yacht in Phuket?

The berth is the easiest line to model because it is usually tied to boat size and, in some marinas, published in advance. It is not the annual ownership cost. VAT and utilities can sit outside the headline berth figure, while yard work introduces another layer: haul-out, wash-down, supports, hardstand time and contractor access. Some of those charges are published; others only exist once the marina or service company has the boat details.

Maintenance is where generic rules become least useful. Engines, generators, batteries, electrical systems, rigging, underwater coatings and other equipment follow their own service schedules and age differently. A blanket rule such as “budget 10% of the boat’s value every year” can therefore be badly misleading: two boats with similar market values may face very different work lists in the same season.

Insurance is quote-driven as well. Vessel value, age, cover, cruising area and insurer requirements all affect the premium, while a major refit can dominate one year and disappear from the next. A sensible owner budget separates expected running costs from a personal contingency for surprises. Crew or management belongs in the model only when the ownership setup actually uses them, not as a compulsory Phuket expense.

A wet berth buys immediacy. The boat is already afloat, connected to marina infrastructure and available without a separate launch request. That convenience also means the hull remains in the water, so fouling, underwater maintenance and shore-power use become part of the ownership pattern even though none can be reduced to one fixed annual number.

Dry stack changes the equation because the boat is stored ashore and launched when needed. It can suit smaller powerboats that are used intermittently, but eligibility is a physical constraint, not a lifestyle preference. Phuket Boat Lagoon states that its 24 covered spaces are for vessels up to 8 metres and 6 tonnes. Royal Phuket Marina’s dedicated premium dry-stack page advertises storage up to 15 metres LOA, while its current wet-berth and hardstand pages still show a 12-metre and 5-tonne limit in their dry-stack summaries. That inconsistency is a good reason to have the marina confirm acceptance for the actual boat before budgeting around it.

Hardstand is different again. It is primarily a working environment for haul-outs, inspection and repair, not simply a cheaper place to leave a yacht. Royal Phuket Marina lists space for 26 vessels, a 50-tonne travel lift, pressure washing, cradles and scaffolding, with metered power and water. Once a boat is ashore for work, the bill can be driven as much by lifting, time on the stand, contractor scope and support equipment as by the storage space itself.

The practical choice therefore follows the vessel and how it is used. A small powerboat may fit dry-stack operations neatly; a large sailing yacht or broad catamaran may not. A yacht normally kept afloat may still move to hardstand for maintenance, while an owner who wants spontaneous access may accept the higher exposure and utility pattern of a wet berth.

At Phuket Boat Lagoon, utilities sit outside the simple berth calculation. The 1 Nov 2025–31 Oct 2026 rate page lists electricity at THB 11/kWh and water at THB 110 per cubic metre. Where metering is unavailable, it states a utility charge of 20% of the berth rate. The marina also says its prices are subject to 7% VAT, so a headline berth number is not the same thing as the invoice an owner should budget for.

Yard work arrives as separate operations. Boat Lagoon’s current HTML page shows a THB 1,500/ft travel-lift rate for the 40–60 ft band: THB 60,000 at 40 ft, THB 75,000 at 50 ft and THB 90,000 at 60 ft. Pressure washing is listed at THB 170/ft, producing THB 6,800, 8,500 and 10,200 for those same lengths. These figures are useful building blocks, not a complete service package. The same rate page separately lists a THB 6,000 cradle set, scaffolding at THB 400 per piece for one month and THB 3,500 multihull support. Small lines like these are why a hardstand invoice behaves more like a work order than a single parking fee. The downloadable official PDF does not show the 40–60 ft lift band, so that rate deserves written reconfirmation before a haul-out is booked.

The contractor fee has an even clearer conflict. The current HTML page shows THB 800/day or THB 10,000/month for outside contractors, while the official PDF for the same rate period shows THB 600/day or THB 7,000/month. A responsible budget should not pick whichever number is lower. Ask the marina office to state the applicable contractor charge on the written quote.

Haul-out and relaunch also need their own billing explanation. A per-foot lifting rate does not automatically tell you whether the return launch is included, charged again or packaged differently, and the published material is not clear enough to justify assuming a total.

Beyond the marina schedule, maintenance becomes vessel-specific. Engine servicing, antifouling, rigging replacement and other technical work should follow the actual equipment schedule and condition, not an invented Phuket frequency. Insurance and major refit work need current quotes as well. The published Boat Lagoon figures make a useful baseline, but the rate card expires on 31 Oct 2026; after that date, treating these numbers as current without a fresh check would be misleading.

A useful annual model starts with the vessel, not with a generic Phuket number. Record LOA, beam, draft, hull configuration and any weight limit that matters to the chosen facility, then decide whether the boat is realistically staying on a wet berth, hardstand or dry stack. Only then does a berth formula become meaningful, because a monohull and a catamaran of the same length can be priced differently and certain berth locations may carry their own surcharge.

Phuket Boat Lagoon provides a clear worked example, but it should stay labelled as one marina’s formula. At THB 920/ft per month, a 30 ft monohull comes to THB 331,200 a year before VAT; 40 ft comes to THB 441,600; 50 ft to THB 552,000. Adding 7% VAT produces THB 354,384, THB 472,512 and THB 590,640 respectively, still before utilities and add-ons. A 40 ft catamaran under Boat Lagoon’s published 50% multihull surcharge reaches THB 662,400 before VAT, or THB 708,768 with VAT. None of those figures is a Phuket market average.

The next layer is planned yard activity. If a haul-out, wash-down, hardstand period or known repair is expected, put it into the model as a separate written quote rather than hiding it inside an annual percentage. Then add vessel-specific maintenance and an insurance quote that actually matches the boat and intended cruising area. This makes it obvious which costs are published and which still depend on the vessel.

A contingency belongs at the end as the owner’s own risk buffer. Its size should reflect the boat’s age, system condition, upcoming work and the owner’s tolerance for an unexpected repair bill; it is not a universal rule of yacht ownership. If the budget is being built after 31 Oct 2026, replace the Boat Lagoon examples with the next rate card or a current written marina quotation before relying on the result.
