The O’Day 35 was one of the most successful cruising designs built by O’Day. Hull construction is a solid laminate of fiberglass and plastic resin Deck construction is a sandwich of balsa core laminated with fiberglass reinforced plastic. Decks, like those aboard most boats built after 1970, are constructed with a balsa wood core to keep the structure light yet strong and rigid. This construction method has proven over the years to be strong and long lasting. There is an interior fiberglass hull liner that forms the lockers, seats and berths as well as well as a considerable part of the support of the hull shell. As it was originally intended to do, the O’Day 35 offers contemporary styling, spacious accommodations and great sailing performance at a reasonable price.
