Design and Construction
The Dash 750's central hull carries marked "steps" that reconcile a narrow waterline beam with satisfactory liveable volume, a configuration retained from the Corsair 24 but boosted by a mast one metre taller. New floats were drawn by the architects to absorb the extra sail area — 5 square metres to windward and more than 15 with the asymmetric spinnaker — and those floats carry 20 percent more volume with a flatter bottom aft to encourage planing. The assembly method was developed so that hull and deck are fitted into each other rather than merely bonded, a structural refinement over the earlier boat. A clever hinging system for the hulls, a convenient tabernacle for the mast, and a retractable bowsprit allow the package to fold and rig with only a wrench and 30 minutes of work.
Rig and Handling
Compared with its predecessor, the Dash 750 is more powerful and with a bigger sail area proves even more exciting on the water, having gained a few horsepower through the more voluminous floats and increased canvas. The 5-horsepower Nissan outboard and 305 square feet of sail support a boat that can match wind speed knot for knot well up into the 20s, a direct expression of the performance step up from the Corsair 24. The taller mast and expanded asymmetric spinnaker plan give the trimaran its punchy character without abandoning the folding convenience that defines the marque.
Accommodations
Inside the central hull, the step offers beam above the settees so that the volume belies the trimaran's narrow waterline, and a twin-berth interior complete with stove, sink, portable toilet, and 12-volt electricity supply supports coastal camping in good conditions. The cockpit is narrow and deep, yet the crew are none the worse for it, and the interior is slightly re-vamped from the Corsair 24. A day-boat sibling under the name Sprint 750 retains an embryo of a coachroof just enough to house a double berth and carries an XXL-sized cockpit, but the Dash 750 itself was found in its sailing configuration unfolded, ready for weekend supplies and short coastal use.
Known Issues
The source material records no documented defects, flooding paths, or structural weaknesses for the Dash 750. The principal cautions are inherent to type: a 5-foot-5-inch draft, 3-gallon water and fuel capacities, and a narrow deep cockpit that trades lounging space for seakeeping. Prospective owners should note the folding hinge and tabernacle systems as central to the trailerable premise, though no failure modes are reported in the source material.
Refits and Ownership
Ownership centers on the trailerable premise: at under 2,000 pounds and folding to 8 feet 2 inches, the boat appeals to those without a permanent slip. The 12-volt supply, portable toilet, and compact galley are owner-serviceable as weekend cruising kit, and the Sprint 750 variant shows the platform's adaptability to day-boat use. The 30-minute rig and hinged hulls keep launch-day labor light, a virtue of the design rather than a later refit.
The Verdict
The Corsair Dash 750 is a focused evolution of the Corsair 24 and F-24 Mark II themes — more sail, taller mast, planing-friendly floats, and a fitted hull-deck joint wrapped around a step-hull that punches above its 24 feet for livable volume. It is a speed-oriented trailerable trimaran with genuine coastal-camp potential, not a pocket cruiser with standing headroom and long-range tanks.
Pros
- Enhanced performance and livability over the F-24 Mark II and Corsair 24
- Folds to 8'2" and rigs in 30 minutes with one wrench
- Step hull delivers interior beam above settees despite narrow waterline
- Planing-oriented floats with 20% more volume than predecessor
Cons
- 3-gallon water and fuel capacity limit range
- Narrow, deep cockpit restricts relaxed cockpit time
- No documented builder upgrades for extended offshore use
