Wat we doen


Custom, semi-custom and series, Cirrus Composites has the capability to do it all. For full production, stable and stiff moulds are constructed, with a suitable surface finish to minimize costs per part. Reusable membranes for the vacuum infusion process can help minimize production costs, and a lot of waste. CNC Kit-cutting and fast cure prepregs help to reduce cycle times for mass Production. Custom boats can be build out off cheaper moulds, or even mouldless in some cases, greatly reducing costs and increasing flexibility. Newbuilds are mainly done in vacuum infusion and out of autoclave prepregs, to keep the weight down, quality high, and process clean. Glass, carbon and flax fibres are the basic builing materials, with (bio) based epoxies, and vinylesters.


There are numerous technologies to produce carbon or biocomposite parts by the hundreds, thousands or more. With high pressure, metal tooling, and high temperature, composites can be pressed in to the desired shapes, and cured within minutes per part. Add in robotic trimming and finishing, and mass production of composites is a cost effective way to cut down on costs, while improving performance. Especially suitable to replace machined aluminium parts with lighter, stronger and cheaper alternatives.


What can be made, can be repaired. Mainly focussed on structural repairs in highly loaded parts, we can repair in house, and on location which is often the case with bigger structures. Keel structures, chainplates, rudders, carbon masts and booms, rotten cores, hulls, trimaran beams, foils, repairs are made to original specifications. And often a bit stronger.


Need a new organiser and a reinforcement in the deck? A cupholder? New winchbase? Perhaps a new bow section? Everything is possible.

Rudders and Foils

Rudders and foils have a special place here. Often high performance parts, where not only strength is important, but where the shape dictates the performance. For new build rudders a CNC machine is used, to mill the core roboticly to tight tolerances. Pockets for reinforcements are cut in to the core too, at the leading edge, trailing edge, and other stresspoints, so the shape stays intact, while adding a lot of strength and damage tolerance. This also creates a strong and thin trailing edge, minimizing turbulence, and maximizing speed and handling. Carbon rudder stocks and blades can be created hollow too, in CNC machined moulds, for the highest performance foils.

Keel shaping is another aspect of the work on foils. Keels often come in less optimal shapes, due to the manufacturing process. With CNC cut templates, and waterproof epoxy fillers, the keel is brought back to the shape intended by the designer, adding a few percent of speed, and improving handling. This can even be done on location with the keel still on the boat.
