Construction STM 4700 SportFun
For building this catamaran the VIP (Vacuum resin infusion process) method is used which has been implemented in shipbuilding since 2002

Hull and deck sections are made with the use of vacuum resin molding technology and modern multiaxial- and 3D-fabrics. All loaded plates are in addition reinforced by "unidirectional fiber". For the hull and deck sections sandwich designs are used filled with Divinycell and HoneyComb fillers.

The hull and deck sections are protected (in addition to vacuum infusion) by a layer of VBC which prevents osmotic damage of fibreglass.

The vacuum infusion allowed us to build extremely strong, hard and at the same time light hulls.

 

The deck section is completely filled with foamed polyurethane (total volume is more than 600 liters).
