Category Description

The existence of semi-displacement yachts is warranted by the need to combine in one hull the best of both worlds: the speed of high-performance planing yachts and the economy of low-speed trawler-type displacement yachts. The predominant difference is in the hull of the so-called transitional type with a special geometry of lines. It provides comfort on board in the speed range of 6–10 knots due to reduced pitch and roll and, at the same time, is able to overcome the hump drag and go out for planing, attaining speeds of up to 20 knots.

Modern transitional hulls that are 30–70 feet long are powered by shaft drives or pods with inboard motors close to the transom, freeing up maximum living space on the lower deck.

These boats are designed primarily for long journeys and are generally equipped with a spacious flybridge for comfortable permanent living on board. They are rightly considered the golden mean for those who want to reduce fuel costs, but are not prepared to move to a real trawler because of its low speed.
