Blow records with an unsinkable, fast and futuristic boat. British shipyard Safehaven Marine has put the 22m XSV20 “Thunder Child II” back into service after an initial launch in mid-February this year. During some tests, immediately after the launch, the boat reached 54 knots thanks to the foil system with which it is equipped. The new golden version does not go unnoticed.

Thunder Child II, born to break records

The XSV20 features an extremely innovative hull design that fuses an asymmetrical catamaran (aft) with a single-hull capable of crossing the waves with a result: catamaran stability in both pitch and roll, monohull top speed.

This boat had already proved to have super seaworthiness performance during a series of tests along the Atlantic coast off in front of Ireland with waves even greater than 5 meters. After the first launch the boat was back in the yard for the installation of the Hysucraft foiling system.

The record in 2020

The bow is able to cut waves like the blade of a knife, while at the stern it splits into two hulls for stability. Catamaran or monohull? Safehaven Marine’s Thunder Child II was born to run on a razor’s edge by concentrating the avant-garde of yacht design and break an ocean record recognized by the International Powerboat Union: cross the Atlantic at full speed, from Canada to Ireland, following the shortest, but very treacherous, route north through ice and storms. This twenty-three-metre boat then will probably start in July 2020.


In addition to the breathtaking design of the Thunder Child II, the engine is also record-breaking: four Caterpillar C8.7 engines of 650 horsepower each, chosen for their power-to-weight ratio, four ZF 325ATS dual-speed transmissions, and four France Helices SDS3L surface transmissions. The top speed is 50 knots, a cruising speed of over 40 knots and is capable of navigating over 800 miles at 30 knots and 1,000 nautical miles at 12 knots.

The vessel has been designed specifically for long-haul oceanic cruises and will accommodate a crew of 6 with on-board facilities with 6 berths in 4 cabins, a galley, and two head compartments. Large long-range fuel capacity is provided by a 7,000-litre main tank and a spare tank with the ability to transfer 2,000 liters of fuel via a transfer system to a bow tank.
