Morgan OI 41 Ketch
Description
The Morgan Out Island 41 Ketch, a ketch-rigged variant of Charles Morgan's iconic Out Island 41 series produced by Morgan Yachts from 1972 to 1978 with an estimated 50–70 hulls in this configuration (out of ~200 total OI 41s), is a full-keel coastal cruiser celebrated for its split-rig balance, expansive liveaboard spaces, and shallow-draft capability that shines in the Bahamas shallows, ICW explorations, or family coastal hops in winds up to 25 knots—featuring a masthead ketch rig that distributes sail area (mizzen ~122 sq ft) for easier short-handed reefing and downwind control, long encapsulated lead keel with skeg-hung rudder for directional stability (PHRF ~150), and a beamy fiberglass hull delivering a soft, predictable motion at hull speeds around 7.8 knots. Owners highlight its secure center cockpit, luxurious teak interior with V-berth forward, U-shaped galley, airy saloon settees, nav station, private aft stateroom with en-suite head, and forward guest cabin sleeping up to 8 under 6'4" headroom, supported by robust tankage (100+ gal water, 60+ gal fuel) for off-grid stays.
