The Cal 35 is an American sailboat that was designed by C. William Lapworth as a cruiser and first built in 1979.[1][2][3]

The Cal 35 is sometimes confused with the earlier Cal 35 Cruise series of sailboats.[1]

Production

The design was built by Cal Yachts in the United States , but it is now out of production.[1][3][4]

Design

The Cal 35 is a recreational keelboat, built predominantly of fiberglass sandwich construction, with wood trim. It has a masthead sloop rig with aluminium spars, a raked stem, a reverse transom, an internally mounted spade-type rudder controlled by a wheel and a fixed fin keel. It displaces 13,000 lb (5,897 kg) and carries 5,200 lb (2,359 kg) of ballast.[1][3]

The boat has a draft of 5.00 ft (1.52 m) with the standard keel and 6.00 ft (1.83 m) with the optional deep draft keel.[1]

The boat is fitted with a Universal diesel engine of 32 hp (24 kW) for docking and maneuvering. The fuel tank holds 33 U.S. gallons (120 L; 27 imp gal) and the fresh water tank has a capacity of 90 U.S. gallons (340 L; 75 imp gal).[1]

Ventilation consists of four opening ports in the main cabin, plus two in the bow cabin. There is a dorade vent over the head. There are also four fixed ports in the main cabin, plus fixed, flush-mounted deadlights over the galley and the forward berths.[3]

The mainsail is sheeted to a mainsheet traveler on the cabin roof. The genoa is sheeted to tracks and is controlled with two-speed winches. There are two halyard winches. The mainsail boom has a topping lift and two internal reefs, an internal outhaul and a boom vang with a 4:1 mechanical advantage.[3]

The design has a PHRF racing average handicap of 136.[3]
