Roberts 36A (Ketch Rig)
Description
The Bruce Roberts 36A, a multi-chine variant of the classic Roberts 36 (also known as Spray 36A), designed by Bruce Roberts-Goodson in the 1970s, is a heavy-displacement bluewater ketch optimized for seaworthiness and long-distance cruising, with hundreds built worldwide for solo or family adventures, many completing circumnavigations thanks to its stable long-keel hull and balanced split rig that reduces weather helm in heavy conditions. This Version A emphasizes affordable DIY construction in steel or aluminum (with fiberglass or wood-epoxy options), offering customizable layouts like center cockpit, pilothouse, or trawler yacht conversions, accommodating 6–9 berths in a spacious interior with full headroom, a U-galley, nav station, and practical storage, powered by a 20–33 hp diesel auxiliary for reliable motoring at 6–7 knots.

Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them.
