Building a Scarab foot 10 moulded trimaran
This is the original Scarab 10. The main hull is made using foam sandwich. The floats and beams were moulded. If I wanted to build more of these boats I already had the moulds for the floats and beams so it was easy to build a plug for the main hull. The boat will still fold using similar system to the Scarab 18 and Scarab 650. The beams make it easy to attach a trampoline. The deck is cut back so the mast with sail attached can be raised without lifting it through the deck like the original Scarab 10. The rig will have a fully battened boomless mainsail and perhaps a jib. The mainsail with have a pocket for the mast. Mast will be round tubes that can be broken down to two pieces for transporting.
Floats
The floats were made in a split mould and the two halves taped together. A gel coat made from cotton fibre and resin was painted into the mould and glass was added. The moulded floats look a bit ragged until they are sanded and painted.
Beams
A beam mould was made over a male plug. Four beams for each boat were constructed with layers of glass and primed.
Main Hull
The main hull had two main parts (the bottom and the deck). That would leave only the one tape that joined them together to finish. The plug was made using scrap foam and glass. Then it was painted and a mould taken for the deck and the bottom of the hull.
