Brian, a "fair market price" is...
What someone will pay for your boat in YOUR local area. All the book prices are a national average that reflects the average condition of the boats sold during any reporting period.. Iow, if only 2 were sold that quarter--one pristine, the other rough--the "book" price will be the average price for those two. Nor do the books take into account the average difference in condition between salt water boats and fresh water boats...local economic conditions (for itnstance, if the biggest employer in the state closes its doors, there are gonna be LOT more boats for sale than there are buyes, resulting in lower prices that lower the national average prices). ...that some makes/models are "hot" in one place, nobody's ever heard of it in another place...a glut of 'em on the market here, hard to find there...even the difference in some new boat prices in the east vs the west...etc. Even nationally, the economy has a huge effect on boat prices. For instance, in 1991 the boat market was in the ashcan...the boat I owned then had a "book" value of $45k. When I sold it 4 years later, the market was strong again....book value was $60k, and I had no trouble selling it for more than that.So the "fair market value" for any boat is its LOCAL value...what they typically sell for in your area. Upgrades and add-ons add only about 10% to survey value of a boat in pristine condition. But they do help it sell a LOT faster than the same boat in pristine condition without 'em.
