Roberts 341
Description
The Bruce Roberts 341, a robust double-ender bluewater cruiser designed in the 1980s by Australian naval architect Bruce Roberts (with refinements by Grahame Shannon), embodies classic seaworthiness for offshore passages or coastal cruising, featuring a canoe stern, long fin or full keel (shoal draft ~5'0"), and skeg-hung rudder for stability and protection, rigged as a sloop or cutter with a generous 621 square feet of sail area yielding a moderate SA/D ratio of ~16 for balanced short-handed handling under a fractional rig (I=47.0 ft, J=14.8 ft, P=41.0 ft, E=14.0 ft). Measuring 34 feet overall (10.36 m LOA), 29 feet waterline (8.84 m LWL), 11 feet 6 inches beam (3.51 m), and 15,000-pound displacement (6,804 kg) with 6,000 pounds of ballast (2,722 kg), it offers customizable fiberglass construction (foam-cored for strength) or steel/wood-epoxy alternatives, with two layouts: aft-cockpit for open-air sailing or pilothouse for all-weather protection, accommodating 4–6 in a practical interior (V-berth forward, U-galley, saloon settees, aft cabin) under 6'2" headroom, powered by a 25–40 hp diesel auxiliary and tanks holding 80 gallons water/40 gallons fuel.
