About the LAGOON 42
Reported SA includes fully battened main + roller furling jib + staysail. Another version was called the MOORINGS LAGOON 4200.
The Lagoon 42 is a fractional sloop catamaran designed by Van Peteghem/Lauriot-Prevost and built by Jeanneau (FRA) and TPI (USA) between 1990 and 1994, with a total production of 51 hulls. This early-generation model represents a significant step in the brand's history, offering a spacious layout that appeals to owners seeking a balance of comfort and performance, though it requires diligent maintenance due to its age and specific structural vulnerabilities.
- Best for:
- This vessel is best suited for coastal cruisers and those seeking a spacious, comfortable liveaboard experience rather than aggressive bluewater racing, given its moderate D/L ratio of 126.98 and comfort ratio of 10.06. It appeals to owners who prioritize interior volume and ease of handling, particularly those willing to invest in significant mechanical and structural upkeep.
- Bluewater capability:
- With a displacement of 16550.0 lb and a capsize ratio of 3.56, the Lagoon 42 possesses moderate offshore capability, though its age and reported critical issues with deck core moisture and rudder systems necessitate rigorous surveying before extended bluewater passages.
- Comparables:
- Comparable boats from this era include the Lagoon 400 and earlier Beneteau catamarans, which share similar beam dimensions and fractional sloop rigs. The Lagoon 42 is also often compared to the Fountaine-Pajot Antares 42 due to similar production years and target markets for coastal cruising.
