Design

Stämpfli currently offers three different hull shapes in the Four/Quad range. We have taken three of the most successful hull shapes in the world and produced light, stiff racing boats that have over the last 20 years won all the major races.

Stämpfli S4 (Long Mould) is a proven fast shape. It is longer than the X4 shape and also has parallel sax boards. Because of the hull shape, it requires more attention to balance the boat and therefore inexperienced crew may find it difficult to sit. It is therefore more of a senior oarsmen's and women's boat, but once mastered, you can expect to produce fast times.

Construction

Stämpfli High Performance boats are manufactured by using Nomex honeycomb sandwiched between high quality high modulus prepregnated carbon (96%) and glass fiber (4%), then heated under vacuum pressure and cured at 130°C (266°F). Stämpfli Club boats are manufactured by using Nomex honeycomb sandwiched between high quality prepregnated carbon (60%) and glass fiber (40%), then heated under vacuum pressure and cured at 130°C (266°F). The resulting bond is 6–8 times stronger than the "wet lay-up" used by other manufacturers.

This substantially increased strength of bond, together with the use of carbon fiber, makes the hull stiffer, more durable and far less susceptible to damage.

Technical Specifications

All hull sizes are built to or below FISA Minimum Weight, and all hulls conform to FISA Buoyancy Guidelines.
