The cheapest part of owning a motor boat is buying it. That sounds like a warning and it is meant as one, but it is also the reason a first purchase goes well or badly: get the budget, the survey and the paperwork right in the first month and the next ten years are simply good weekends on the water.
Before you sign anything
- Budget 8 to 15% of the purchase price every year to run the boat, 10% being the standard rule of thumb.
- A pre-purchase survey costs around 25 to 40 dollars per foot, with a floor near 500 dollars, and pays for itself on the first fault it finds.
- In France, a licence is required above 4.5 kW of administrative engine power, roughly 6 hp.
- French registration paperwork now runs entirely online and takes four to eight weeks.
Start with the three things you will really do
Write down the three activities that will fill most of your outings. Towing children on a ring, fishing at dawn, running to a restaurant along the coast, diving, or simply cruising slowly with the family. Those three lines choose your hull, and everything after that is detail.
The classic first-purchase mistake is buying for the fourth and fifth activities, the ones you picture doing once a summer. A boat that tries to fish, cruise, sleep four and pull a wakeboarder does all of it adequately and none of it well, and you pay for the compromise in berth fees every month of the year.
New or used, honestly compared
New buys you a warranty, a known history and a boat that will not surprise you in its first season. Entry-level pricing is lower than people expect: in the 2026 US catalogues a SUN TRACKER Bass Buggy 16 XL Select pontoon lists at 19,795 dollars with its engine, and a TAHOE T16 at 23,595 dollars. Around the French Riviera, dealers in Golfe-Juan and the neighbouring marinas carry the same class of boat alongside larger cruisers.
Used buys you more boat for the money and takes the worst of the depreciation off your hands. It also buys you somebody else’s maintenance decisions, which is exactly what a survey exists to uncover. For a first boat under 8 metres, a well-kept used hull with a recent engine service is usually the better value, provided you actually commission the survey rather than talking yourself out of it.
What it costs after the purchase
The number that governs ownership is not the price on the advert. It is the annual running cost, and the industry rule of thumb is to set aside around 10% of the purchase price each year. Ownership guides published in 2026 put the realistic band at 8 to 15% depending on size, age and where the boat lives.
| Cost item | What to plan for |
|---|---|
| Pre-purchase survey | About 25 to 40 $ per foot, minimum around 500 $ |
| Haul-out for inspection | Roughly 10 to 20 $ per foot |
| Engine survey | Around 100 to 180 $ per hour |
| Annual running costs | 8 to 15% of purchase price, 10% as a working figure |
Berthing is the line that varies most. A marina pontoon on a busy stretch of coast can cost several times what the same boat pays on a swing mooring or on a trailer at home, and in some ports the waiting list matters more than the price. Sort out where the boat will live before you buy it, not after.
The survey and the sea trial are not optional
Commission an independent surveyor, not one recommended by the seller, and be present for the inspection if you can. On a used hull the survey looks for osmosis and moisture in the laminate, structural repairs, corroded through-hull fittings, tired wiring and gas installations, and the general question of whether the boat has been used or merely stored badly.
The sea trial answers a different question. Take the boat out in conditions closer to real than ideal, run the engine up to full throttle and hold it, then bring it back to cruising revs and listen. Check that it planes cleanly, that the steering is not vague, that the trim works and that nothing overheats. Engine hours matter less than how the hours were spent: a well-serviced 600-hour engine beats a neglected 200-hour one every time.
Paperwork, using France as the worked example
Registration and flag are two separate things in France. Immatriculation identifies the vessel, while francisation gives it the French flag and becomes compulsory from 7 metres of hull length or 22 administrative horsepower. Both processes have been fully online since 2022 through the national administrative portal, with a processing time of roughly four to eight weeks.
Buying a boat that is already registered, you should receive the original francisation certificate, a signed bill of sale and the vessel record. You then have one month to declare the change of owner to the maritime authority. The registration number stays with the boat and only the holder changes.
Then there is the annual francisation and navigation duty, calculated on hull length and engine power, with an abatement according to the boat’s age. Published guidance puts it in a range from around 50 to 2,500 euros a year. Verify before signing that the current year has been paid, because an unpaid balance stays attached to the vessel and lands on you.
Licence, insurance and the kit that has to be aboard
In French waters a permis plaisance is required to helm anything with an engine rated above 4.5 kW, which is roughly 6 horsepower. It is the administrative rating that counts, not the commercial one printed on the cowling, and the two do not always match.
Insurance is a different matter from a car. Third-party cover is not universally compulsory for pleasure craft, but virtually every marina, club and dry-stack operator will require proof of it before allocating a berth, and the obligation varies by country. Safety equipment is not negotiable anywhere: life jackets for everyone aboard, a fire extinguisher, signalling and the rest of the list set by your national regulations for the navigation category you intend to sail in. Check the local requirement rather than assuming, and have any work touching steering, fuel systems or structure done by a qualified marine technician.
Should I buy through a broker or privately?
A broker costs more and handles the paperwork, escrow and title checks, which on a first purchase is money well spent. Private sales are cheaper and put every one of those checks on you. Either way, the survey is the same and so is the sea trial.
How much boat should a first-time owner buy?
The smallest boat that covers your three activities. Smaller hulls are easier to handle, cheaper to berth, simpler to trailer and far less punishing when you misjudge a docking manoeuvre, which you will, several times, in the first season.
Curious about the other end of the market?
Before you settle on a conventional hull, it is worth seeing what happens when a boat leaves the water altogether.
Updated August 2026. Boat prices are 2026 US manufacturer list prices including engine; survey, haul-out and running cost figures come from published marine surveyor rates and 2026 boat ownership cost guides; French registration, francisation and licence requirements reflect current national procedures and the 4.5 kW licence threshold. Rules, taxes and insurance obligations differ by country, so confirm them locally before buying. This article is general information and not legal, tax or technical advice.
