The one we are showing all season

The 43 is the boat Signature is putting in front of people from Newport to Annapolis this autumn, and the reason is simple: it is the size most buyers actually land on, and it is rated CE Category A — ocean, not coastal. That rating is not a marketing line. It changes what you are allowed to plan.

The bow cabin idea

Lagoon moved the owner’s berth forward, away from the engines and away from whatever is happening in the cockpit. It sounds like a small thing on a plan drawing. Sleep aboard one night at anchor with guests still up and it stops sounding small.

One room, not two

The opening between salon and cockpit was widened until the two stopped being separate spaces. Twelve people can sit down to dinner without anyone being sent to the other side of a bulkhead — which, for a boat of forty-three feet, is the whole argument for a catamaran in one sentence.

Worth knowing before you fall for it. Reviewers note the 43 carries about 1,800 kg more than the 42 it follows, which shows in under ten knots of true wind. Worth a sea trial if your home water is light-air.
