The Corsair Cruze 970, also called the Corsair 970, is a Vietnamese trailerable sailboat that was designed by the Corsair Design Team as a cruiser and first built in 2012. The boat is a development of the Corsair 31.[1] [2] [3] [4] [5]
The design has been built by Corsair Marine in Vietnam since 2012 and remains in production.[1] [2] [5] [6] [7]
The design is based on the Corsair 31, which was in turn based on the Farrier F-31. The designer, Ian Farrier, had sold the rights to the F-31 to Corsair in 2000.[1]
The Corsair Cruze 970 is a recreational trimaran, built predominantly of fiberglass over a PVC core. It has a fractional sloop rig with a rotating airfoil mast and a bowsprit. the hull and outriggers have plumb stems and transoms. The main hull has a kick-up, transom-hung rudder controlled by a tiller and a retractable daggerboard. It displaces 48080NaN0 and carries no ballast.[1] [2]
The boat has a draft of 6.89feet with the daggerboard extended and 1.48feet with it retracted, allowing operation in shallow water, beaching or ground transportation on a trailer.[1] [2]
The design has a beam of 8.33feet with the outriggers folded for docking or trailering and 22.57feet with them unfolded for sailing.[1] [2]
The boat is normally fitted with a small outboard motor for docking and maneuvering. The recommended engine is a 9.90NaN0 Yamaha Corporation four stroke, high thrust, extra long shaft.[1] [2]
The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and an aft cabin with a double berth. The galley is located on the starboard side just forward of the companionway ladder. The galley is equipped with a two-burner stove and a sink. The head is located just aft of the bow cabin on both sides. The fresh water tank has a capacity of and the holding tank has a capacity of .[1] [2]
For sailing the design may be equipped with 448square feet screecher or a spinnaker of 992.43square feet.[1] [2]
The design has a hull speed of 7.56kn.[2]
Naval architect Robert Perry wrote in a 2013 for Sailing magazine, "I don't think you would spend much time under power in this tri. The SA/D is 36.47, and that's a lot of sail power per pound, easily enough to give you very good light air boat speed. The mast is a rotating wing. A carbon fiber bowsprit allows you to fly either a 448-square-foot screecher or an 893-square-foot chute. That is enough off-the-wind sail area to provide for some very exciting sailing. For some comparison, the 893-square-foot spinnaker is bigger than the entire rig of the Cal 40."[8]
In a 2014 review for Cruising World, Tim Murphy wrote that the "970 features much thinner, higher-aspect-ratio foils that are optimized for speeds in the teens and higher. (A note to those who haven't sailed Corsairs before: Those boat speeds are real. Try it!) ... We sailed the 970 in light air. With the screacher up in 8 to 10 knots of breeze, we posted 6.6 knots just above 60 degrees apparent, then cracked off and made 7.6 knots."[9]
