The Portman 36 is an American sailboat that was first built in 1978.[1][2][3]

Development and production

The silent partner in Auroraglas purchased the rights to the center-cockpit Coronado 35/Columbia 36 design from Columbia Yachts and the tooling was modified to become the aft-cockpit Portman 36. Other modifications included relocating the ports from the hull to a newly designed coach house and designing a new hull-to-deck joint.[1][3][4]

The design was built by Auroraglas and later by Watkins Yachts in Clearwater, Florida, United States after the acquisition of Watkins and its merger with Auroraglas. A total of 19 boats were produced, with Auroraglas only building one or two of them, before production moved to Watkins.[1][2][3][4][5]

The design was developed into the Watkins 36 and the Watkins 36C in 1981[1][2][3][4]

Design

The Portman 36 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a raised transom, a skeg-mounted spade-type/transom-hung rudder controlled by a wheel and a fixed fin keel. It displaces 16,000 lb (7,257 kg) and carries 6,000 lb (2,722 kg) of ballast.[1][2][3]

The boat has a draft of 4.50 ft (1.37 m) with the standard keel fitted.[1][3]

The boat is fitted with a diesel engine of 40 hp (30 kW) for docking and maneuvering. The fuel tank holds 60 U.S. gallons (230 L; 50 imp gal).[1][3]

The design has a hull speed of 7.26 kn (13.45 km/h).[3]

Operational history

The boat is supported by an active class club, the Watkins Owners.[6]
