Roberts Spray 27 (Bermudian Sloop)
Description
The Bruce Roberts Spray 27 in its Bermudan sloop rigging—also known as a Marconi rig with a single mast, triangular mainsail, and headsail—is a modern, efficient setup favored for its simplicity and upwind performance, contrasting the more traditional gaff rig option. This configuration enhances the boat's trailerable coastal cruiser profile, delivering approximately 355–360 square feet of sail area (mainsail plus genoa) for responsive handling in moderate winds, while maintaining the design's hallmark stability from its long-keel hull. Builders can adapt the standard trunk cabin or pilothouse layout to this rig without major modifications, using steel, aluminum, fiberglass, or wood-epoxy construction for a loaded displacement of 4,023 pounds and trailerable weight under 3,300 pounds.
