Design limits set by the EU Recreational Craft Directive (2013/53/EU), in significant wave height. A category covers the conditions of those below it. It is the limit the boat was designed to, not a promise that it is safe in any conditions within it — that judgement stays with the skipper.

About Extra Yachts

Semi-custom

Italian yacht line of Palumbo Superyachts, founded in 2017 — eight models in four lines (Fast, Triplex, Global, Shadow) from the 17-metre X56 Fast to the 44-metre X145 Global explorer, in GRP, carbon, aluminium or steel.

Extra Yachts says it was founded in 2017 to create a deep connection between the owner, the sea and nature, and that it specialises in yachts with a bold, distinctive personality. Its lines run from 17 to 45 metres, plus a 30-metre power catamaran, all designed for generous indoor and outdoor living, low fuel consumption and extended autonomy. The brand was born from the technical expertise of Palumbo Superyachts, and the yard presents this as giving its clients the benefits of belonging to a major international group. On sustainability it points to low-resistance hulls that come out of a meticulous engineering process, and it describes its work as resting on craftsmanship, carefully sourced materials, research and technology.
