The US 21 design was developed into the Triton 21 in 1984, after Bayliner sold its US Yachts line of boats to Pearson Yachts.[1][2][3][4][5]
The design was built by US Yachts in the United States, starting in 1982, but production had ended by 1984 when the product line was sold to Pearson Yachts. The molds were the used to build the very similar Triton 21.[1][2][3][6]
The US 21 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig; a raked stem; an open, walk-through, reverse transom; a transom-hung rudder controlled by a tiller and a lifting keel. It displaces 1,700 lb (771 kg) and carries 200 lb (91 kg) of ballast.[1][2][3]
The boat has a draft of 4.58 ft (1.40 m) with the centerboard extended and 1.25 ft (0.38 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 3 to 6 hp (2 to 4 kW) outboard motor for docking and maneuvering.[2]
The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and a two straight settee berths in the main cabin. The galley is located on the port side just aft of the bow cabin and is equipped with a sink. The head is located in the bow cabin on the port side under the "V"-berth. Cabin headroom is 48 in (122 cm).[1][2][3]
The design has a PHRF racing average handicap of 201 and a hull speed of 5.7 kn (10.6 km/h).[2]
In a 2010 review Steve Henkel wrote, "best features: The U.S. 21's light weight should make her relatively easy to trailer, launch. and retrieve, though perhaps not as easily as the Newport 212. Her PHRF rating, well below that of her comps, intimates that she is fast. Worst features: Her high SA/D. wide beam, and low ballast compared to her comps may mean she needs more beef on the rail in heavy air to keep her upright."[2]
