Like the others posted, NADA is fairly worthless for most sailboats. It works fine for cars. If you want the price of a 2007 Toyota Camry, they can calculate a fairly accurate average for the 500,000 or so Camry sold that year. It just doesn't work for a sailboat that might have 20 sisterships that year.
It's really easy to get a car from Florida
up to New York
, so location is not such a big factor for a car, but for a sailboat location can be a large factor.
Someone may spend 5% of the value of the boat just for electronics
, cars don't see the same number of 'add ons' that a boat can get.
That cool flame paint
job on a car won't affect the resale value much, but spray new awlgrip on a 15 year old boat and it has a big effect on price.
Your bank on the corner of Main Street in Boise, Idaho may not know any better than to lend on NADA or BUC value, but I believe most real Marine
finance companies have access to and know to use soldboats.com for approximating value.
