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.

Helsinki builder of aluminium deep-V 'crossover' boats — ten models in three series, the DFNDR multi-purpose boats, the DSCVR day cruisers and the EXPLR cabin boats, from the 8-metre DFNDR 8 to the 13.4-metre EXPLR 44, Best Big Boat at the 2025 Best of Boats Awards.
XO Boats describes itself as coming from the northern, rugged archipelago of Finland, whose Baltic surroundings it says inspired both its design and its philosophy of boats that last a lifetime. Its concept is the XO Crossover: a deep-V hull of what it calls the best military-grade aluminium on the market, joined to fibreglass for the design, giving a recreational boat the qualities of a professional vessel — a rigid, light hull that needs little maintenance and can be fully recycled at the end of its life. The EXPLR 9, which made its debut at Boot Düsseldorf in 2020 and was improved in 2021, was the first of the second generation of XO boats, with more width and volume than its predecessors. The DFNDR 9 had its global debut at the Southampton Boat Show in 2021 and was named Adventure Boat of the Year 2023; the yard then drove one 400 nautical miles across the Baltic from Helsinki to Stockholm with Motor Boat & Yachting. The smaller DFNDR 8 was launched at Boot Düsseldorf in 2023, and in 2025 the company premiered the EXPLR 44 there, its first aluminium adventure yacht, which went on to win Best Big Boat at the 2025 Best of Boats Awards.
