Roberts Henry Morgan 57

Description

The Bruce Roberts Henry Morgan 57, a robust pilothouse ketch (or cutter ketch variant) designed by Bruce Roberts-Goodson in the 1980s as a heavy-displacement bluewater motorsailer inspired by traditional privateer lines, is engineered for long-range cruising, chartering, or family ocean passages with exceptional stability and load-carrying capacity, boasting hundreds of fiberglass builds worldwide that have tackled Pacific Gyre routes and global voyages. Measuring 57 feet LOA with a 14-foot-6-inch beam, 7-foot-3-inch draft on a full-keel hull, and around 76,000 pounds displacement (including 30,000 pounds of internal ballast for superior righting moments), it features a balanced split rig for easy short-handed sail reduction—delivering efficient light-air performance under a Perkins 120 hp diesel auxiliary (with generator backup) and generous tanks holding 300 gallons of fuel and 400 gallons of water for extended autonomy. The voluminous interior accommodates 9–13 in four cabins across two full heads with showers, a full galley boasting diesel oven, microwave, washer/dryer, and ice maker, plus a spacious saloon, nav station, and twin helms (pilothouse and cockpit) for all-weather command, all customizable via DIY plans emphasizing seaworthiness with recent refits like epoxy barriers and anti-fouling for 20-year hull protection; build costs typically range $200,000–$400,000, while used 1980s–1990s examples fetch $30,000–$145,000, making it a timeless choice for adventurers seeking luxury without fragility.
