Good old boats if you like traditional low aspect rigs, long keels and thick laminations. Check the mast step (on keel). It''s made of plain steel and the first place to look. Limited access makes it very difficult to inspect or replace. Get the sawzall out. Next check the rudder post and stuffing box...I''ve seen two of these cracked just inside the hull but repair is easy. The last M35 I looked at had about 5 million dime size bubbles on the bottom.
