In Deep Water Yachts’ Korvet passage makers, form follows function

THE HAGUE – Peter Bost, founder and managing director of Deep Water Yachts, swears by the form-follows-function principle. Just look at his Korvets. Lightweight aluminum passage makers, they make the point a boat’s shape should relate to its intended function or purpose.

For Deep Water Yachts, that formula works like a dream. The yard was created in 2015. Since then, it has developed five vessels, all built for strength: it is now finishing its third Korvet 14 CLR. In 2019, it delivered a 59ft Korvet 18 LowRider and will start on a 56ft Korvet 17 LongRange this year. Peter Bost: “With the Korvet 14 CLR, designer Willem Nieland created a remarkable first design that won the 2015 European Powerboat of The Year award.”

Korvets, he says, must feature the highest quality construction, materials and finishing. They must have excellent seaworthiness, sailing characteristics, redundancy in all vital systems and self-sufficiency for long voyages to remote areas. Korvets are suited for harsh sea conditions, but their shallow draft is ideal for exploring inland waters, tidal inlets or even sit out a tide on a mudflat.

Deep Water Yachts works with industrial shipbuilding partners. “That means we exceed standards for recreational vessels,” says Bost. “Our clients are invariably experienced sailors, who have switched to a motorboat but don’t want to give up their sailing areas.”

The partnership with half a dozen maritime companies “keeps overhead costs relatively low and we can work with the most suitable parties for each project,” says Bost. “All of the companies involved have been selected for their expertise. Mutual processes are professionally blended, and construction is done efficiently and effectively.”

The partners are Willem Nieland Design, Shipyard Rotterdam, Frisian Shipbuilding Lemmer, DKS carpentry, Ship Install, Brown Marine and RVS Perfect.

True to the ‘form follows function’ school, “application is the starting point and form derives from that,” says Bost. “For example, we started with an easy-to-access, full-width engine room. So, no squeezing through hatches to replace a filter. Also, no concessions to negotiating French canals. This allowed us to go up in height with the superstructure and give the vessel a timeless, nautical design.”


Korvets lack a paint system with putty. “Tanks are integrated into the hull, which gives it much rigidity,” Bost says. “Aluminum makes a Korvet very robust, light and easy to maintain. Our desire was to achieve a cruising speed above the theoretical hull speed of 6-7 knots. That plus a fast-displacement hull shape, gives a Korvet a cruising speed of 10 knots at around 60% engine load.”
