A Unique Offering
EXTREME H2O is the most exciting Gunboat 66 available today!
“Extreme H2O” is arguably one of the highest performance cruising catamarans, worldwide. With no expense spared - this boat was conceived to set the bar for high end performance cruising/racing catamarans, world wide.
A comfortable, attractive, modern interior, belies the no holds barred approach to performance - incorporating numerous state-of-the-art performance design concepts.
The Design Philosophy
A product of the Morrelli & Melvin Design & Engineering design office, “H2O” was optimized for performance throughout a wide range of wind conditions.
A Southern Spars rotating wing spar is coupled with an aft beam traveler, tiller steering for racing, mainsheet controls at all steering stations and a powerful sail plan, with a full inventory of high performance sails. This powerful sail plan is managed with advanced sail handling systems, with 4 high speed hydraulically driven winches in the forward cockpit, and at all steering stations, with an additional push button mainsail trim.
Morrelli & Melvin's designed “C” foils 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.
All of this is coupled with a fully integrated hybrid drive system, with retractable propeller drives, to minimize drag.
The result - performance of up to 30 knot sailing speeds, without sacrificing the luxury features one expects in a yacht of this category.
“Extreme H2O” began construction at the Gunboat yard, in South Africa. After Gunboat closed its doors, the boat was moved to the US and completed by Westerly Marine - a custom boat builder, founded in 1970, and located in Santa Anna, California - specializing in Carbon Fiber Performance Vessels. Over 56,000 hours were required to complete the boat to certified standards.
Hulls: Carbon inner skin and outer skin / 25mm Corcell Sandwich
Cabin: Carbon inner and outer skin / Nomex honeycomb and Corcell sandwich
Cabin soles: Carbon / Nomex honeycomb sandwich
All secondary taping Carbon fiber / Epoxy and post cured
All laminates vacuum-bagged and post cured.
All of Extreme H2O power requirements such as refrigeration, instrumentation, lighting, winches are run easily run from the battery bank. The large inverters allow use of Aircon throughout the night without the use of generators. The boat has a battery operated powering range of 45 minutes, without the use of generators.
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.
An elegant, comfortable, extremely fast catamaran - setting the bar for large performance racing/cruising catamarans - worldwide. And all of this - housed within the elegant look of the iconic, Morrelli Melvin designed Gunboat 66.
This boat has to be seen, to be truly appreciated. So, if your interest is the ownership of a boat which is truly a cut above - an eye catcher. One that can cruise in elegance and comfort - and yet will set the bar, when racing with the best of breed. Then this is a boat you need to seriously consider.
Our firm (Morrelli & Melvin) was responsible for the design of all the early Gunboats (the GB48, GB62, GB66 and GB90 designs). These are the designs that established Gunboat’s reputation. We have also been closely involved with the continuing support and design improvements on these boats, for the last 10 years. As such, we know the boats very well. This is the case with "Extreme H2O", as well – having been involved in her design, her build and ongoing improvements. As such, we are very qualified to speak to her history, characteristics, and capabilities (as with any of the original Gunboat designs). A viewing of our company web site (www.morrellimelvin.com) will provide background on the performance pedigree that went into this design (world ocean record setters such as “Playstation”, America’s Cup defenders, such as “Stars & Stripes”), and those which have followed (subsequent Americas Cup challengers and defenders, Olympic class designs, etc). “Extreme H2O” comes from this world renown performance stable.
We would look forward to introducing you to this vessel. So please do not hesitate to contact us should you have any questions on the boat - her design, build, history, etc.
