Candidate Models / Lagoon 40 (2017-)

Lagoon 40 (2017-)

Specs summary: popular entry-level cruising catamaran. This is a near-miss on the stated envelope only because the published LOA is about 38 ft 6 in (slightly under the 39 ft lower bound). Otherwise, beam/draft and air draft are a good match (air draft is comfortably under 63 ft).
