The Sun Fast 20 is a French trailerable sailboat that was designed by Polish naval architect Jacek Centkowski as a cruiser-racer and first built in 1985.[1][2][3][4][5][6][7]
The Sun Fast 20 is part of the Sun Fast sailboat range.[8]
Production
The design was built by Jeanneau in France starting in 1985, and Poland starting in 1993. Production in 1999 with 500 boats completed.[1][2][3][7][9][10][11]
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]
