The Lagoon 421 represents a summary of the expectations of this category of cruising catamarans. She benefits from all the strong points the Lagoon 420 is famous for:
Outstanding comfort for a 42′ catamaran including an independent washroom with toilet and shower for each cabin. A safe and comfortable deck layout (wide side decks, easy circulation, excellent overall ergonomics)
The famous “gullwing-shaped” bridge deck prevents slamming into big waves is continued forward so as to receive the anchor roller and an optional strut to fit a gennaker.
The Lagoon 421 also features a large number of improvements directly inspired by the numerous owners’ suggestions:
More dynamic lines and a lowered profile with the same comfort
A new and lowered fixed bimini, for better protection from the sun and the spray
Optimized hull lines with redesigned underwater hulls shape aft
Light grey tinted windows and hatches for an even nicer ambiance and more natural light.
For good performance in light air, the Lagoon 421 is available with a square-top mainsail configuration.
