The Stratus 36, also called the 107 Stratus for its metric length in decimetres, is a Swedish sailboat that was designed by Peter Norlin as an International Offshore Rule Three-Quarter Ton class racer-cruiser and first built in 1980.[1][2][3][4]

The design is a development of Regnbagen, a one-off boat that won the Three-Quarter Ton class Cup in Hundested, Denmark in 1979.[1]

Production

The design was built by Albin Marine in Sweden between 1980 and 1984, with 130 examples completed. After Albin production ended a few boats were built in South Korea between 1984 and 1986, but it is now out of production.[1][2][5][6]

Design

The Stratus 36 is a racing keelboat, built predominantly of fibreglass, with wood trim. The early boats built had teak decks. It has a 7/8 fractional sloop rig with a deck-stepped mast, aluminum spars, wire standing rigging and a single set of unswept spreaders. The hull has a raked stem, a reverse transom, an internally mounted spade-type rudder controlled by a wheel and a fixed fin keel. It displaces 11,466 lb (5,201 kg) and carries 4,960 lb (2,250 kg) of lead ballast.[1][2]

The boat has a draft of 5.90 ft (1.80 m) with the standard keel.[1][2]

The boat is fitted with a Swedish Volvo Penta MD-11 diesel engine of 23 hp (17 kW) for docking and manoeuvring. The fuel tank holds 60.8 U.S. gallons (230 L; 50.6 imp gal) and the fresh water tank has a capacity of 118.9 U.S. gallons (450 L; 99.0 imp gal).[1][2]

The design has sleeping accommodation for five to seven people, with a double "V"-berth in the bow cabin, two straight settees in the main cabin and an aft cabin with a double berth on the starboard side and a single berth on the port side. The galley is located on the port side just forward of the companionway ladder. The galley is equipped with a three-burner stove, with an oven and a double sink. A navigation station is opposite the galley, on the starboard side. The head is located opposite the galley on the starboard side.[2]

For sailing the design may be equipped with a symmetrical spinnaker of 969 sq ft (90.0 m2). It has a hull speed of 6.99 kn (12.95 km/h).[2]
