Check out the Bayliner Buccaneer series. Made in the 70''s of heavy fiberglass, rot resistant plywood cored decks and more room than boats much larger. Because they have an undeserved bad rep and you can get a 28 foot boat with a diesel and
wheel steering in good shape (as good as any other 20 year old boat) often for less than 10k.
There are specs and pics at www.geocities.com/buccaneersailboats
as well as opinions by owners who sail them, not yachties that just spout uninformed opinions.
