The Nor'Sea 27, or Norsea 27, is an American trailerable sailboat that was designed by Lyle Hess as cruiser and first built in 1976.[1][2][3]
Production
The design was built by Heritage Marine, later renamed Nor'Sea Marine, in Dana Point, California, United States . Production was started in 1976, with 450 boats built, but it is now out of production.[1][4]
The boats were sold complete and ready to sail and also as kits for amateur completion.[5]
Design
Hess designed the boat in response to a specification by Dean Wixom, president of Heritage Marine, who was looking for a trailerable boat that could handle almost any ocean weather. Hess based the configuration on the traditional lines of the Norwegian Spitzgatter.[5]
The Nor'Sea 27 is a recreational keelboat, built predominantly of fiberglass, with wood trim and a plywood-cored deck. It has a masthead sloop rig with a bowsprit, a spooned raked stem, a rounded transom, a keel and transom-hung rudder controlled by a tiller and a fixed long keel with a cutaway forefoot. It displaces 8,100 lb (3,674 kg). Until 1980 a choice of 2,500 or 3,000 lb (1,134 or 1,361 kg) of ballast was available. After 1980 ballast was standardized at 3,100 lb (1,406 kg).[1][3][5]
The hull design is 27.00 ft (8.23 m) long or 31.00 ft (9.45 m) with the bowsprit.[5]
A tall mast of 34.5 ft (10.5 m) with 376 sq ft (34.9 m2) of sail, as well as a short mast of 30.5 ft (9.3 m) and 335 sq ft (31.1 m2) of sail, were available.[1]
The boat has a draft of 3.50 ft (1.07 m) with the standard long keel.[1]
The boat is fitted with a Faryman diesel engine of 9 hp (7 kW) or a Yanmar 2GM diesel of 20 hp (15 kW) for docking and maneuvering. The fuel tank holds 27 U.S. gallons (100 L; 22 imp gal) and the fresh water tank has a capacity of 50 U.S. gallons (190 L; 42 imp gal).[1][5]
The design has two cabin configurations, both with sleeping accommodation for four people. The center cockpit-aft cabin version has a double berth aft and a drop down dinette table that converts to a double berth in the bow. The aft cockpit configuration has a bow cabin and two berths aft, under the cockpit. Both have a galley located on the starboard side just forward of the companionway ladder, equipped with a two-burner stove and a sink. The head is located opposite the galley on the port side. The cabin has 71 in (180 cm) of headroom.[1]
Operational history
A review in Blue Water Boats noted, "the Nor'Sea 27 is a small but rugged pocket-cruiser with live-aboard comfort and seaworthiness at the heart of her design. Designer Lyle Hess was approached with the challenging brief to design a heavy weather, long distance cruiser which could be legally trailerable. Unfazed, Hess came up with this tough and traditionally styled 27-foot double-ender which is transportable between oceans if not strictly trailerable."[5]
