As exhilarating as it is luxurious, the Extreme H2O racing catamaran seamlessly blends breathtaking performance with eye-catching design. Meticulously customized from the ground up, Extreme H2O truly stands in a category of its own.
Aesthetically arresting carbon fiber appointments throughout the cabins and structural components not only provide extreme strength, but also extreme sophistication. All of these structural and technical advancements make Extreme H2O one of the most impressive performance cruising catamarans in the world.

Extreme H2O is the lightest and fastest Gunboat 66. The boat features a fully integrated hybrid system, C foils, T rudders, a Southern Spars rotating wing spar, aft beam traveler, retractable propeller drives, tiller steering for racing and push button mainsheet controls at all steering stations.
State-of-the-art Morrelli & Melvin foils and a powerful sail plan with masthead screecher that sheets to the forward cockpit for light air upwind performance and a full inventory of downwind furling sails make “H2O” an extremely capable catamaran in a large crossover of wind conditions. Speed and performance did not sacrifice the luxury features of this cruising catamaran - which can realize up to 30 knot sailing speeds.
The fully integrated hybrid system will allow you to depart the dock, enjoy a day of sailing and return to the dock without ever having to listen to a diesel motor. Better yet, you can enjoy a tropical night at anchorage with 30,000 BTU of air-conditioning without the noise of a generator.
Completed in 2015 – “Extreme H2O” has already raced to Mexico and Hawaii and back and is fully serviced with a new 3Di raw racing mainsail a new R1 reacher and ready for racing and cruising in the Caribbean in 2017.
“Extreme H2O” is the first Gunboat 66 to place an emphasis upon performance cruising
catamarans. A product of the Morrelli & Melvin Design & Engineering office, “Extreme H2O” was optimized for performance throughout a wide range of wind conditions. You can enjoy sailing at over 9 knots of boat speed in only 8 knots of wind on “H2O” which is unheard of on other comparably sized catamarans.
This powerful sail plan is managed with advanced sail handling systems in both the forward cockpit with 4 high speed hydraulically driven winches and at all steering stations with push button mainsail controls. In addition, the mainsheet traveler is curved along the length of the aft beam for optimum mainsail control and safety. The running sails are all controlled through bottom up or top down furling and the mainsail is reefed with state of the art locks at the head and clew.
Morrelli & Melvin designed the “C” foils to provide up to 4,000 kg of vertical lift and the “T” rudder to reduce pitching when the wave angle is forward of the beam. The “T” foils are removable while boat is in the water so the boat can be easily configured for optimum speed and comfort.
“Extreme H2O” began construction in South Africa by Gunboat. After the Gunboat facility shut down, the boat was moved to the US and completed by Westerly Marine - a custom boat builder located in Santa Ana, California. Westerly Marine specializes in carbon fiber performance vessels. Over 56,000 hours were required to complete the boat to certified standards.
