Designed for Barry Houghton, the Salperton IV is 45 meters long. An Ed Dubois design boat, it features interiors designed by the Adam Lay Studio.

The $30 million vessel is in many ways a redesign of its predecessor, the Salperton III yacht. It features a bimini larger than the Salperton III, shading the cockpit. Built-in mini sofas have replaced the chairs in the bimini.

Carbon-fiber handrails, wheel and other fittings in the cockpit are complemented by matching carbon-fiber and teak outdoor furniture. It displays sleeker aesthetics to deliver a better sail performance.

Constructed entirely from 5,083 marine-grade aluminum, the yacht displays a curved exterior. It also features a 9.3 meter beam and a 4.75 meter fixed draft.

Being longer than its previous model, the yacht offers large cockpit area and a more spacious engine room and lazzerette below. It is powered by 875hp Caterpillar C18D diesel engine that achieves top speed of more than 15 knots.

It has a fully air-conditioned interior with a sewage treatment station that can make up to 15 tons of water a day, and is capable of carrying 30 tons of fuel.

The interior features an owner’s cabin and three guest cabins, one of which can be converted to a gym. Up forward, three more rooms accommodate the six member crew of the boat. The forward deck also includes the spa pool.

Salperton IV features automated systems that display touch controls like its pneumatic pop-up helm stations. Custom treated imported door latches, light switches and saloon sofas define the interior space of the yacht.

Crafted walnut cabinetry and waxy-coated, oyster oak flooring embellish the entire yacht. Solid marble from the quarry in Italy, purpose-cut in Auckland, is used on the bathroom floors.

The yacht showcases the same expanse of skylights from Salperton III that covers the saloon area. These lights help illuminate the lower levels and connect the indoors with the exterior. Fake portlights, composed of a pane of glass lit from the inside with lights, illuminate the cabins.

Salperton IV features the Future Fibers PBO rigging, while its boom bears advanced features that make it easy to hoist and furl the 573 square meter main sail.
