The idea

Quattroelle began with a provocation from an owner who had owned three white yachts and was bored of all of them: draw me something my harbourmaster will recognise blindfolded. The answer is a reverse bow that leans into the sea instead of away from it, and a superstructure of four stacked glass bands that read as one continuous horizon line.

“A profile should be recognisable from a mile away — Quattroelle is recognisable from three.”

What she entails

The full-height glazing is structural, bonded into the aluminium superstructure so mullions all but disappear. Aft, the decks step down in three open levels to a beach club with fold-down balconies on both sides. The owner's apartment occupies the entire upper deck forward, with a private terrace that no guest deck overlooks.

Below the waterline, a displacement hull with interceptor trim keeps 21-knot sprints honest and 12-knot passages transatlantic — 5,500 miles without refuelling.
