The J/27 is a keelboat built by J/Boats. It is both a weekend cruiser and a One-Design racing class with strict class rules. Designed with a low, heavy keel with a generous sail area, the boat gives good handling in both light and strong winds, but struggles in moderate winds.^[1][2]

Design

The J/27 is a Fractional rigged sloop designed by Rod Johnstone and built by Tillotson Pearson, Inc. between 1983 and 1992. 211 boats were built before it was replaced by the J/80.

A large cockpit and open decks allows crew to move around easily, and the Fractional rig means that sail costs are kept down.

The boat has four bunks, and a galley with a standard water capacity of five gallons. Below decks headroom is 4.5 feet (1.4 m). The boat has an outboard engine placed on the transom (port side).
