About

This project is dedicated to the design and construction of a custom carbon fiber catamaran that using foiling technology to obtain at least an 80% lift to increase speed, enhance stability but retain the refined characteristics of a cruising catamaran. These boats will be part of a charter fleet that brings the true essence of sailing to people around the world.  We also donate time on the boats to local boys and girls clubs, and organizations dedicated to youth programs.  We have teamed up with the best in the industry to try to develop this new style of cruising catamaran. Peter Johnstone who is the founder and CEO of Gunboat will be the builder. Peter and his staff are the leaders in building carbon fiber catamarans. The DNA Design Team from Holland will be involved with the design of this new class of catamaran. DNA is best known for the three-time World Champion DNA A-Class catamaran. As the dominant design team in the most prolific development class, the DNA team designed and built A-Class cats for nearly every top America’s Cup sailor for training. HOLLAND COMPOSITES will build the pre-preg carbon G4 in their immaculate high tech facility.

LATEST TECHNICAL ACHIEVEMENTS:

1. T-FOIL RUDDERS: The rudders feature foils at their tips. The foils stabilize the boat, reduce pitching in a seaway, and securely hold the bows up when pressed downwind.

2. L-FOIL DAGGERBOARDS: When you achieve a 2.7 ton displacement, lifting foils make a significant contribution to performance. The L-foil daggerboards provide lift, reduce drag, and keep things safe when pressed downwind.

3. CENTRAL SPINE CREATES LOW WINDAGE: We are fond of wedding cakes, but a cat cannot perform when it looks like one. Windage with such a design is akin to driving a car with the hand-brake engaged. The GUNBOAT G4 utilizes a central structural spine to handle the rig loads. The spine enables a low-slung pilothouse with minimal windage, which greatly reduces drag and increases performance.

4. EVERY OUNCE COUNTS! At this size, weight is key to performance. The GUNBOAT G4 is ALL CARBON and ALL PRE-PREG EPOXY, post-cured in an oven for added strength. The Nomex honeycomb core is the lightest available. Every piece of the composite platform and rig is CARBON.

5. MAINSAIL CONTROL SYSTEM: A light cat requires easy control of the mainsail. The helmsman trims the mainsheet with foot-pedal hydraulic pumps, and eases with the push of a button. The GUNBOAT G4 is the first high-performance cat to allow such short-handed control and safety.

6. SHOAL DRAFT: When you arrive at your cruising destination, you will feel at ease, knowing that this cat should draw less than 3′. With rudders, daggerboards, and props all fully retracted, you’ll be free to skim over skinny waters

The technical design will address the balance issue for the boat. Balancing the weight, lift and stability of the catamaran at lift is crucial to enable to boat to perform at speed while limiting the possibility of capsize.

Risks and challenges

One of the biggest challenges with this project is finding the right balance between the lifting characteristics of the c foils or J foils (depending on which foil system we decide to use), the weight of the cruising catamaran, and the stability and performance characteristics we are trying to achieve. When you have a 100% foiling boat, the ability for that boat to remain stable is vital. If the bows plunge too quickly, or the lateral stability becomes compromised, there is a high likelihood the boat could capsize. In order to overcome the obstacles we have experts from the leading carbon fiber catamarans, leading experts in foiling technology, and the premier catamaran designer. This team has been assembled to conquer this task.
