  • Close-hauled under mainsail and jib: 6.4 knots
  • 45° angle from the wind with mainsail and jib: 8.1 knots
  • Wind on the beam with mainsail and jib: 6.4 knots

« Coming out of the channel we met the full swell. The Lagoon 421 barely lost her way, pitched only slightly and did not slam into the waves. A good point for those wanting to sail long distances, and that probably means the majority of owners! » Multicoques Magazine, FR / Multihulls World, UK – April 2010
