The US Yachts US 25 is an American trailerable sailboat, that was designed by Gary Mull and first built in 1981. The design is out of production.[1][2][3][4][5][6]

Derived from the Buccaneer 250, the US 25 was later developed into the Triton 25 and produced by Pearson Yachts.[1][5][6]

Production

The boat was built by US Yachts, a division of Bayliner, which is itself a division of the Brunswick Boat Group, which is in turn owned by the Brunswick Corporation.[1][5][6]

Design

The US 25 is a small recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, an internally-mounted spade-type rudder and a choice of keels. The boat was produced with a standard fin keel, an optional shoal draft keel or a centerboard.[1][2][5][6]

It displaces 3,750 lb (1,701 kg) and carries 1,250 lb (567 kg) of ballast.[1] The boat has a hull speed of 6.2 kn (11.48 km/h).[2][5][6]

The boat is normally fitted with a small 4 to 8 hp (3 to 6 kW) outboard motor for docking and maneuvering.[1][6]

The design has sleeping accommodation for five people, with a double "V"-berth in the bow cabin, a drop-down dinette table that forms a double berth in the main cabin to port and an aft quarter berth on the starboard side. The galley is located on the starboard side amidships. The galley is equipped with a two-burner stove and a sink. The enclosed head is located just aft of the bow cabin on the port side. Cabin headroom is 66 in (168 cm).[6][7]

The design has a hull speed of 6.2 kn (11.5 km/h).[6]

Operational history

In a 2010 review Steve Henkel wrote, "A large foretriangle and a blade-like small mainsail gives the appearance of a fast racer, but in reality the boat does not stand out as a particularly fast boat. Best features: Construction was quite good—better than the chopped strand” powerboats built by Bayliner in the early days. Trim included teak and holly sole and other niceties Worst features: The pinched bow gives too little room for a full V-berth; use it for small kids only."[6]
