Design and Construction
The Sprint 750 shares its hull design with the Dash 750, carrying the same large buoyant floats, beams, and folding system. The folding arrangement is the heart of the boat's practical appeal: the outer hulls fold up to a street-legal 8 feet, 2 inches street-legal 8 feet, 2 inches, and the whole package can go from dock to trailer in minutes, then roll down the freeway at 60 mph without a permit. That fold also yields compact, affordable storage when the season ends. Structurally, the boat draws nearly five and a half feet with the alloy daggerboard down, yet with the board raised it slips into water as shallow as one foot. A mahogany and ash tiller drives the dagger-type rudder, which keeps the boat very maneuverable and responsive in close quarters.
Rig and Handling
Above the deck sits a rotating aluminum wing mast held by synthetic shrouds and a stainless steel forestay. The sail plan centers on a 262-square-foot mainsail worked through a 6:1 mainsheet system, with two Harken 16 primary winches and four clutches managing sheets and halyards. A retractable aluminum bowsprit sits ahead of the anchor well hatch, ready for a screecher or spinnaker — add either and the trimaran will fly downwind. boats.com recorded the Sprint sailing at or above 20 knots in the right conditions, stable and powerful enough to cover 50 miles on a good afternoon. The retractable daggerboard and rudder are what make gunkholing possible once the speed run is done.
Accommodations
This is a boat dedicated to sailing, with the cockpit eating up most of the length and sized to accommodate a racing crew. Below, the cabin is deliberately spartan — a small double bunk forward where the crew tosses gear, a separate area set aside for a portable MSD, and a beige carpet liner finishing the space. A four-switch panel runs the interior and running lights. The priorities are clear: accommodations space is secondary to the Sprinter's drag-racing speed potential, and the result is an ideal daysailer rather than a weekender.
Known Issues
The known-service facts that matter to an owner are about wear points inherent to the design: the folding system and alloy daggerboard/rudder are moving metal in a saltwater environment, and the synthetic shrouds and trampoline nets are UV- and load-cycled items that age. The cockpit-dominated layout means the small cabin's carpet liner and portable MSD area can trap dampness if gear is stowed wet. These are the usual trimaran service items a buyer should expect to maintain.
Refits and Ownership
Ownership centers on the trailerable lifestyle. The mast can be winched up with a gin pole, so stepping and unstepping is a one-person job at the ramp. Grey wing nets and optional bow nets connect to the large-volume amas and complete the spacious deck, and these are straightforward to replace. Because the boat folds to a narrow road width and tows without a permit, storage and transport costs stay low compared with a fixed multihull kept on a mooring.
The Verdict
The Corsair Sprint 750 is a pure-expression daysailing trimaran: light, folding, and genuinely quick, with a cockpit built for a crew and just enough cabin to shelter gear and a tired sailor. It trades liveaboard comfort for road-going freedom and 20-knot potential.
