Design and Construction
Corsair built the 970 at a single factory in Vietnam, applying careful building techniques including vacuum bagging, and period reviewers judged the construction quality quite good — better than the California-built 31s built at a single factory in Vietnam. The company backs the structure with a five-year warranty and passes along manufacturers' warranties on installed hardware. The hull and deck are fiberglass with a PVC foam core, and the folding mechanisms that tuck the amas inboard for trailering are carried over, well-refined, from previous versions rather than reinvented. Notably, Corsair added more furniture in the cabin yet kept the weight the same as the 31, a trick that pays off in livability without punishing performance.
Rig and Handling
The 970 trades the 31's foils for much thinner, higher-aspect-ratio ones optimized for speeds in the teens and higher, and the boat will routinely knock off double-digit speeds and can show what 20-plus knots feels like higher-aspect-ratio foils. In light air, test sailors flying a screacher in 8 to 10 knots posted 6.6 knots just above 60 degrees apparent, then cracked off to 7.6. Owners report the blade jib buys 15 degrees closer windward ability. With a 44.95-foot mast and a fractional sloop rig on a 31.82-foot trimaran, the platform's added buoyancy and longer amas keep it flat and composed where the predecessor would have felt tender.
Accommodations
The 970 deftly makes space for both an aft cabin and an aft cockpit arrangement, and the cabin gains headroom over the 31. Writing in Cruising World, the reviewer praised two very comfortable park benches in the cockpit, a layout that turns the broad beam into usable lounging and steering space rather than a bare trampoline span. The cabin headroom gained over the 31 and the aft-cockpit combination give the boat a genuine weekend-cruising feel while preserving the run-around room on the trampolines that only a trimaran affords.
Power and Trailering
The 970 offers no inboard option; the tested boat carried a Yamaha 9.9-horsepower outboard on the transom, with a steering arm on the tiller and remote engine controls in the cockpit no inboard option. That keeps the hull simple and the weight down. The amas fold inboard for trailering, and with the daggerboard up the boat can sit in a foot and a half of water, be parked on the beach, or tucked into a little lagoon — a flexibility no monohull in this size range can match.
The Verdict
The Cruze 970 is a thoughtful evolution of the Corsair 31 that trades a little of the old boat's low-speed docility for a stiffer, faster, more livable platform. The longer amas and added buoyancy make it steadier at speed and more comfortable at anchor, while the carried-over folding mechanism keeps trailering painless. Construction quality and the warranty package suggest Corsair took the redesign seriously.
Pros
- 20 percent more buoyancy and longer amas than the 31 for a more stable platform
- Higher-aspect foils and light-air performance into the teens and beyond
- Aft cabin plus aft cockpit with added headroom and comfortable cockpit seating
- Folding amas, beachable hull, and shallow draft for lagoon access
- Five-year structural warranty and improved Vietnam-built construction
Cons
- No inboard engine option; dependent on outboard for propulsion
- Thin high-aspect foils optimized for speed rather than forgiving low-speed handling
