Range, not speed

Twin John Deere diesels, 8,500 litres of fuel and a claimed transatlantic range in the region of 3,500 nautical miles. The EIGHTY 3 is not built to be fast; it is built so that the crossing is a decision about weather rather than about fuel stops.

Launched in Miami, February 2026

This is a brand-new boat. Everything published so far — including here — comes from the builder’s launch material rather than an independent sea trial. We will update the page when the first proper reviews land.

Worth knowing before you fall for it. Lagoon’s EIGHTY 3 imagery is still 3D — the boat only launched in Miami in February. The renderings are accurate to the build; ask us if you want photographs of the Miami hull.

What the judges and the testers said

Awards are listed as won or nominated, never blurred together. Launch previews written from renderings are marked as previews, because they are not sea trials.
