Re: Sailboat under $5000 for Puget Sound
1) Ask for the exact product used for the paint. Enamel is too generic of a term and perhaps he used real bottom paint.
2) Most boats made in the last 40 years for your price range have an interior fiberglass liner that provides the structure for the furniture. Was that removed for this boat, or is it just that additional furniture (new table, shelves, simple stuff) was made with non-marine wood? If his woodwork is non-structural, is functional, and isn't ugly then it's probably not a major problem.
When I bought my Pearson there were just about as many boats being sold in Anacortes and Bellingham (about an hour from each other) as in the Seattle-area.
boats that I sail on regularly: Pearson 28-2, Rondar 505, Yankee 30, Blanchard Junior
