Beneteau First 405
Description
The Beneteau First 405 is a performance-oriented masthead sloop designed by Jean Berret and built by Beneteau in France from 1983 to 1987. As a standout in Beneteau's early First line, it was engineered for IOR 1-ton racing while offering solid coastal cruising capabilities, with a fin keel for upwind speed and a spacious interior for family weekends. Approximately 200 units were produced, many still racing in PHRF fleets or cruising globally. Variants include a shoal-draft keel (5'7") for shallower waters and 2- or 3-cabin layouts. Owners praise its "balanced and lively" handling and handsome lines.
