The patented hull design incorporates several innovative features:
The tunnel chines (two longitudinal steps on each side,) break up the solid water to form a two phase medium before it hits the tunnel roof (wet deck). This assures a comfortable, shock-free ride in rough water.
The sponsons (demi-hulls) are a-symmetrical with convex non-trips to guarantee banking to the inside in turns. This feature provides excellent straight-line stability, as well as safe and comfortable turning.
The symmetrical bows provide plenty of displacement up front to prevent any chance of ‘stuffing’ or broaching. Being symmetrical they also prevent any see-sawing (veering from port to starboard) when quartering seas.
Where continual operation at high speed and in all weather conditions is required the BOBKATTM patented SKOKBREKER (Shock Breaker) can be fitted, which reduce slamming against the tunnel roof in high sea states.
The high tunnel is another feature that provides several benefits:
Head seas can be taken at speed, it allows fast backing-up without swamping the rear deck and makes trolling and loitering in following seas dry and safe.
The swim platform at the transom protects the drive system and allows recovery at near water level in safety. Not only does the shape of the sponsons give a soft and safe ride, the shapes also provide inherent strength to the hull, reducing weight of the fibreglass lay-up.
Centre of Gravity position is not critical on this hull design which allows people to move around without upsetting stability or overall performance. Preferred
position remains at 35% – 40% of waterline length, which is easily achieved in a practical layout.
Superstructures can be constructed out of GRP, sandwich, aluminium or even wood to suit the requirements of the end-user. Because of the high metacentric height of the basic hull, the deck structures can be high and wide to fully take advantage of the very large space available.
We have adopted the use of a hydro-foiling technique to create a more effective vessel
Increased Speeds
Semi-foiling increases top speeds by at least 20% whilst increasing comfort and stability even further inrough seas.
Reduces Drag
The foils carry between 40% to 75% of the vessel’s displacement. This reduces the hulls’ volume which greatly decreases drag and improves seakeeping.
Reduced Fuel Consumption
Reduced drag on the underwater sections of our vessel improves efficiency. This results in lower propulsion requirements, reduced fuel consumption, and a lighter vessel.
“A part of a boat or ship serving as a shelter for the person at the wheel.”
The wheelhouse is the power center for your boat and so its design and finish are crucial to our customers. With such a varied and versatile number of ways of customising and configuring the layout of this internal space, the wheelhouse becomes a personal signature for the owner of the boat.
With plenty of room for seating, a galley, control panels and entertainment outlets, the wheelhouse can be made as comfortable as your living room at home, or be used to fill all of the requirements to use your vessel commercially.
We use the latest and most tried and tested materials
in our manufacturing process.
Fibreglass is the key building block in our catamarans, as its durability, flexibility and versatility make it ideal in boat building. Its bulk strength and weight are better than many metals, and it can be more readily moulded into complex shapes. By laying multiple layers of fibre on top of one another, with each layer oriented in various preferred directions, the material’s overall stiffness and strength can be efficiently controlled.
With very little wood being used, the boat is strong, lightweight and much less prone to rot and water damage. Instead an incredibly strong material known as Nida-core is used to stiffen laminates at a fraction of the weight of solid fibreglass.
