What a Wooden Boat Actually Costs to Own
Twice the cost of GRP if you pay a yard, a fifth of it if you enjoy sanding. There is no version in between.

Ask a wooden boat owner what it costs and you get one of two answers, wildly apart, and both are true.
If a yard does the work: two to four times what the same boat would cost in GRP. If you do it yourself and enjoy it: not much more than GRP, plus every other weekend from March to May.
How much does a wooden boat cost to maintain?
A 40-foot carvel-planked hull, yard-maintained, in a temperate US climate:
| Job | Frequency | Cost |
|---|---|---|
| Haul, pressure wash, antifoul | Annual | $2,200 to $3,500 |
| Brightwork maintenance coats | Twice a year | $3,000 to $6,000 |
| Topside paint refresh | Every 3 to 5 yrs | $4,000 to $9,000 (amortised $1,300) |
| Seam and fastening checks | Annual | $800 to $2,000 |
| Covered winter storage | Annual | $2,500 to $5,000 |
| Contingency | Annual | $1,500 |
That lands between $11,000 and $19,000 a year. The same boat in GRP is $3,000 to $5,000.
Now do it yourself. The materials for a season of varnish and paint are $600 to $1,200. Antifouling is $400 of paint and a weekend. Suddenly the number is $4,000 to $6,000, most of which is storage you would pay anyway.
That gap is the entire economics of wooden boat ownership, and it explains why the market for them is small and self-selecting.
The jobs that actually hurt
Recaulking. Not annual, despite the mythology. A sound carvel hull goes 8 to 15 years between serious seam work. When it comes, $8,000 to $20,000 on a 40-footer, and the real risk is what the yard finds once the seams are open.
Refastening. If the boat was built with galvanised fastenings and they are going, you are looking at a five-figure job that has to happen. Bronze-fastened hulls largely avoid this, which is why buyers pay a premium for them.
Deck seams. Teak-over-plywood decks leak at the seams eventually, and water in the deck core is the classic slow killer. Inspect them before anything else.
Where the money is well spent
Covered storage. It is the single highest-value line in the budget for a timber boat, and the one owners cut first when money is tight.
A wooden hull under cover in winter dries evenly, does not take UV, and does not sit full of rainwater. Outside under a tarp, it does all three. The difference in deterioration over a decade is not subtle, and the storage premium is $1,500 to $3,000 a year against repair bills that run into five figures.
The honest position
I like wooden boats and I would not recommend one to somebody who is buying a boat to go boating.
If the sanding is a chore standing between you and the water, you will resent it by the second season, and a resented wooden boat deteriorates fast. If the sanding is part of the appeal, and for a lot of people it genuinely is, then the yard bills above never apply to you and the whole calculation changes.
Be honest with yourself about which one you are before you sign, not after.
Frequently asked questions
- How much does a wooden boat cost to maintain?
- Roughly $9,000 to $18,000 a year for a 40-footer if a yard does the work, against $3,000 to $5,000 for GRP. Owners who do their own varnish, paint and seasonal work commonly bring it under $4,000, which is why so many wooden boats are owner-maintained.
- How often does a wooden boat need recaulking?
- A carvel hull typically needs seams looked at every 8 to 15 years and fully recaulked less often than that. A full recaulk on a 40-footer runs $8,000 to $20,000 depending on access and how much fastening work it uncovers.
- Do wooden boats leak?
- A carvel-planked hull takes up water for the first days after launching, which is normal and not a leak. Persistent weeping after the planks have swollen is a problem, and it usually points at fastenings or a seam that has worked loose.
- Is varnish work really that time-consuming?
- Yes. Brightwork wants two maintenance coats a year in a sunny climate and a full strip and rebuild every five to eight. Budget 40 to 80 hours a season on a boat with substantial exterior varnish, or $3,000 to $6,000 to have it done.
