About the HULLMASTER 27
Also known as the HM 27.
Designed by Ted Brewer and Robert Walstrom, the Hullmaster 27 is a rare, heavy-displacement cruising sloop with only 40 hulls built in 1974. Produced by Hullmaster Boats, Ltd./DS Yachts (CAN), this vessel combines a 7400.0 lb displacement with a 332.41 D/L ratio, indicating a solid, motion-dampened platform.
- Best for:
- This boat suits coastal cruisers and conservative bluewater sailors who prioritize stability and comfort over speed, particularly those seeking a manageable 27.25 ft LOA with substantial ballast.
- Bluewater capability:
- With a low 1.9 capsize ratio and 3000.0 lb of ballast, the Hullmaster 27 is well-suited for offshore passages, offering a stable platform that resists capsizing and provides a comfortable motion in heavy seas.
- Comparables:
- Comparable to other Ted Brewer designs of the mid-1970s such as the Bristol 27 or Island Packet 26, due to the shared emphasis on heavy displacement, fin keels, and robust construction for offshore safety.
