Moody 31
Description
The Moody 31 is a popular British family cruiser designed by Bill Dixon and built by A.H. Moody & Sons Ltd. (Southampton, UK) from 1983 to 1987, with 259 hulls produced in fiberglass. It features a modern fin keel (or optional twin bilge keels) with skeg-hung rudder for balanced handling and protection, a masthead sloop rig for straightforward sail management and good all-around performance, and a spacious, practical interior (sleeps 6 in V-berth + saloon settees + aft cabin, galley, enclosed head) with excellent headroom and storage—widely regarded as one of the best 30-footers of its era for comfort, seaworthiness, and build quality (thick hull laminates, solid teak joinery).
