Seacart 30 Buyer's Guide
Shopping the brokerage market for a Seacart 30 means taking on a folding one-design trimaran with an all-carbon hull and a racing soul, built by Marström in Sweden from a Marc Lombard design. These are not coastal cruisers with creature comforts; they are trailable speed machines whose used-market presence spans several European and American regions.
Layouts on the Used Market
Every example follows the one-design format, so the core platform is consistent: a main hull with berth flats fore and aft, a double berth on an inflatable mattress, and three additional single berths in a deliberately Spartan interior finished in raw black carbon fiber. The accommodation steers crews toward hotel stopovers rather than onboard living, and the folding amas splayed at about 4.5 degrees let the boat be towed behind a small car.
Equipment and Common Upgrades
Used boats commonly carry a code zero, gennaker, asymmetric spinnaker, trampoline, autopilot, AIS, and lithium batteries as standard trailerable-racer kit. Often-seen items include a spinnaker and chartplotter. For buyer consequence, the power and energy cluster of lithium batteries is common, while solar and a furling main appear as less frequent owner upgrades. A short-handed setup is sometimes added by owners rather than factory standard.
What to Inspect
The known construction points are the all-carbon hull and the side escape hatch in the main hull, and the deep centerboard trunk drawing 6 feet 7 inches when down should be cycled to confirm the board and up position at 1 foot 2 inches. The full-length chine and no-deadrise sectional shape are fixed design traits rather than defects.
Availability and Buyer's Takeaway
Typical markets for these boats are the United States, Denmark, Italy, and the United Kingdom. A buyer should confirm the folding mechanism and wing mast pivot, check the centerboard operation, and verify the carbon interior is intact.
- Confirm folding amas and trailering condition
- Cycle centerboard through full draft range
- Verify wing mast pivot alignment
- Check escape hatch seal and carbon hull finish
