The DAFN was France's annual tax on registered boats. Weblex explains it's now the taxe annuelle sur les engins maritimes à usage personnel, plus a separate tax on large yachts. The Var maritime office says it applies to boats over 7 m, engines over 22 administrative horsepower and personal watercraft over 90 kW.
How it's worked out
On hull length and engine power, with reductions for older boats. Weblex's table exempts hulls under 7 m and engines up to 5 administrative horsepower, and charges more as both go up. It's paid at registration and then every year before 1 April.
What a buyer checks
When the seller last paid it, and what you'll owe from the next 1 April.
