The quick verdict

The Lagoon 380 is a long-running, widely built catamaran that is easy to find on the used market, with asking prices that vary a lot by year and generation. Owners praise its roomy interior, simple rigging and comfort, but expect slow progress upwind and in light air. Before buying, get a detailed survey covering hulls, decks, bulkheads, rudder bushings and saildrive seals.

Proven ocean-crossing record; Roomy, comfortable interior for its length; Sturdy, well-built hulls; Simple rigging that suits novice crews; Good value for money on the used market

Slow to windward and in light air; Poor pointing ability from fixed mini-keels; Limited storage; Interior fit and finish not high quality; Rudder bushings wear and need periodic replacement; Saildrive seal and bellows deterioration; Hobby horsing in waves; Possible balsa-cored deck or hull delamination; Limited storage and tight galley space

Owner experience & independent reviews

Owner experiences and professional commentary are separate sources. Condition varies from boat to boat.

What owners report

  • An owner reporting 15,500 miles praises the accommodation and relatively high bridgedeck clearance, but reports cracks in engine lazarette hatches. Read source
  • Early models can be awkward when furling the genoa because the helm lacks a second winch; an owner also reports difficult-to-trace wiring. Read source

What the magazines say

  • Practical Sailor highlights roomy accommodation, a sociable cockpit-level helm and the model’s strong record as a cruising and charter catamaran. Read source
  • Canadian Boating praises the flexible three- and four-cabin layouts and accessible sail controls, while noting the updated version had not yet been sea-trialed for its review. Read source
