Average price of annual boat maintenance ?

[MathGeek]

Costs vary greatly with the specific boat. I've owned a 16' aluminum boat with 20 hp motor for a long time, and $500/yr seems about right. Add $100 a year for the trailer.

But add horsepower to the motor, lots of electronic accessories in the boat, or a desire to keep fiberglass looking perfect, and costs escalate quickly. A 20' bay boat with a 200 hp motor is an entirely different deal.
