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.

Austrian family shipyard founded by Engelbert Frauscher in Vienna in 1927 and based near Gmunden on Lake Traunsee — eighteen design-led sports boats and electric boats from the 6.1-metre 610 San Remo to the 15-metre 1414 Demon, including the electric Frauscher x Porsche line.
Engelbert Frauscher, born in 1903 in Aspach in Upper Austria's Innviertel, trained as a carpenter and boatbuilder and in 1927 took over a boat-building shop on the Old Danube in Vienna, where he built rowing and sailing boats, including two Olympia-Jolle dinghies for the Austrian team at the 1936 Olympics. The Vienna shop was badly damaged in an air raid in 1944; after the war he serviced the yacht club's boats for the American forces in Gmunden and then bought the Weyer shipyard there, where the family repaired boats, ran a boat rental, built O-Jolle and Zugvogel boats and the first wooden electric boats, followed by the motorboats Fish and Starfish once his sons Ernst and Hans had joined. Hans Frauscher began building in polyester in 1971, the brothers merged their firms in 1972, and when motorboats were banned on Lake Traunsee in the late 1970s the electric boat took over, with several hundred leaving the new yard at Moosham from 1976; the H-boat licence of 1979 brought more than 600 boats and four world titles. The third generation joined from 1982, Frauscher Bootswerft GmbH & Co KG was formed in 1993, and after a fire in 2001 destroyed the boathouse and 60 boats a new one was built in 2002. The 717 GT was Powerboat of the Year in 2010, a modern shipyard opened in Ohlsdorf in 2012 together with a sales base at Port Adriano in Mallorca, the 1414 Demon of 2016 took the yard from the lake to the sea, and Port Grimaud followed in 2019.
