I am planning to sell my 1997 boat soon. It is in very good condition, engine, hull, interior. My husband and I are discussing different approaches. He wants to try for two weeks to sell it as is. I want to get the bottom pressure washed and painted, change the zincs, and shine the hull. Which approach is better for netting the most money in the sale? Will the extra work produce enough of an increase in the sale price to cover the expense?
