Corsair C37 Buyer's Guide
The Corsair C37 on the brokerage market is a 2009-designed folding trimaran from Corsair Marine, built in two versions — the fibreglass C37CR cruiser and the full-carbon C37RS racer — that fold to a 3.0 metre beam for trailering yet open to 7.8 metres with directional-stability amas. A used example rewards a buyer who understands the multihull's shallow-draft, beachable nature and its modest house-power budget rather than expecting a conventional monohull's systems.
Layouts on the Used Market
Every C37 folds via a lightweight aluminium system and draws only 0.51 m hull-only, or 1.83 m with the daggerboard down, with the rudder retracting alongside it for grounding. Below, the bow V-berth sleeps two, the aft cabin a double reached through the companionway steps, and the main-cabin dinette converts to a further bunk for six total. The saloon's curved U-settee seats six around an FRP table, and the galley — whether the two-burner gas or alcohol version seen across reviews — pairs a sink with slide or cabinet storage and built-in 12v refrigeration on the cruiser. A moulded head with shower and pump-out sits forward, and the aft cabin holds an escape hatch with one hatch on each float and tinted polycarbonate windows throughout.
Equipment and Common Upgrades
A chartplotter is commonly fitted, often a flip-out unit near the companionway sharing data with cockpit and cabin. For buyer consequence, the energy side matters most: the standard 9.9 hp Yamaha outboard carries only an 8 amp alternator feeding two deep-cycle batteries, while a 20 hp four-stroke is the listed upgrade for longer cruising. Navigation and deck lighting run through a breaker panel with dual battery selector, and a VHF masthead antenna and compass are typical. Sail handling centres on Harken self-tailing primaries, mast halyard winches with rope clutches, and a carbon bowsprit for screacher or spinnaker; a self-draining anchor locker and transom shower round out the exterior.
What to Inspect
The one documented limitation is electrical: reliance on the small 8 amp alternator of the 9.9 hp Yamaha four-stroke outboard leaves onboard power limited, charging the deep-cycle pair to no more than 14.5 volts anchor. On any candidate, confirm which engine is fitted and whether the 20 hp option or a larger charging path was added. Otherwise the known structure is sound — vacuum-bag vinylester and foam with Kevlar key-part reinforcement, nine-bolt ama arms with corner cables, and foam giving positive buoyancy if inverted — so inspect the folding arms, stainless linkage to the carbon rudder, and hatch seals as routine, not as flagged defects.
Availability and Buyer's Takeaway
These trimarans typically appear in the United States. A short checklist for the shopper: verify the engine hp and alternator output against your cruising plans; exercise the aluminium folding system and check ama bolt backing plates; confirm the carbon rig and bowsprit condition; and test the self-draining cockpit, anchor locker, and escape hatch. The C37 is a capable, beachable cruiser-racer whose only systemic caveat is modest stock electrical generation.
