Evelyn 25.5
Description
The Evelyn 25.5 is a light-displacement racer-cruiser sailboat designed by Bob Evelyn (Robert Evelyn), an American naval architect and builder known for his performance-oriented designs in the early 1980s. Introduced in 1981, it was built by Formula Yachts (Bob Evelyn's own company in Connecticut, USA) in fiberglass (FG) construction, with a fin keel and transom-hung rudder, masthead sloop rig, and a focus on spirited sailing—offering quick acceleration, good upwind ability, and fun handling for club racing or coastal cruising while providing basic overnight accommodations (berths for 4–5, small galley, head, and V-berth forward). Production was limited (likely low dozens, as part of Evelyn's small-series output before the company ceased around 1985), making it a rare and collectible classic today, often praised for its generous sail plan relative to displacement and lively performance in its size class. Some examples feature inboard auxiliary engines (e.g., small diesel or outboard bracket).
