Build process

Shipman carbon yachts are built with revolutionary production boatbuilding methods.

The new award-winning SPRINT technology from SP Systems enables a one-shot construction. The epoxy resin is in gel form and enclosed between two layers of fibers which permit evacuation of air trapped between the layers by means of vacuum. The void content achieved is under 1% and the fiber content close to 60%. Typically, with a common hand lay-up process as widely used in the boat-building industry, a limit for fiber content is approximately 30–40%.

A high temperature oven is used to produce a controlled 24 hour, 90 degrees C curing cycle. The curing process is computer controlled and seven temperature gauges in the laminate and molds permit perfect control of the prescribed temperature curve. During the process, the epoxy resin melts, infuses the surrounding fibers and cures to final hardness.

The hull and deck of every Shipman boat are chemically bonded, and the hull and the upper flanges of the bulkheads are chemically bonded to the deck using Spabond 345, an epoxy-based adhesive. Once this operation is cured, the final stiffness of the boat is achieved.

All main bulkheads are structural and built in female molds using the same technology as the hull and deck: carbon fibers, epoxy resin and a high-density core, vacuum bagged and oven-cured. The structure is made in female molds, laminated using Sprint and, after oven-cure, bonded to the hull with Spabond 345 material.

A keel structure with longitudinal girders forms a strong and stiff backbone of the boat. A stiff boat is not only safer, easier to handle but also much faster and more forgiving, enabling more power transfer and control from the rig, which is best noted in higher overall and VMG speeds.
