Design

The Sun Fast 20 is a recreational keelboat, built predominantly of polyester fiberglass, with the deck having a balsa core. It has a 7/8 fractional sloop rig, with a deck-stepped mast, a single set of swept spreaders and aluminum spars with continuous stainless steel wire rigging. The hull has a slightly raked stem, a walk-through reverse transom, a transom-hung rudder controlled by a tiller and a retractable lifting keel. It displaces 1,720 lb (780 kg) and carries 595 lb (270 kg) of cast iron ballast.^[1][2][3]

The boat has a draft of 4.26 ft (1.30 m) with the keel extended and 0.82 ft (0.25 m) with it retracted, allowing operation in shallow water, beaching or ground transportation on a trailer.^[1][2][3]

The boat is normally fitted with a small outboard motor for docking and maneuvering.^[1][2][3]

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settee berths in the main cabin. The head is a portable type and is located in the center of the "V"-berths.^[1][2][3]

For sailing downwind the design may be equipped with an asymmetrical spinnaker of 304 sq ft (28.2 m²), flown from a retractable bowsprit.^[1][2][3]

The design has a hull speed of 5.82 kn (10.78 km/h).^[2][3]

Operational history

The boat was at one time supported by a class club that organized racing events, the Sun Fast Association.^[12][13]
