TC 790 Racing Catamaran

This boat could be the answer for those who want something bigger than a beach cat, with the same thrills, but without the big boat price tag. With minimum material costs and no hull mould to build this would be ideal for the enthusiastic amateur builder.

The hulls are 4mm plywood tortured into shape, then fibreglassed inside and out. Cedar stringers and foam/carbon ring frames will reinforce the structure, while the forward berth will be a long structural subdeck, finishing behind the main beam. The curved deck will be ply bent over stringers and frames.

Hull access will be via a midships hatch, with 1.4m headroom and two berths per hull. However it is more likely that cooking and sleeping will happen under a boom tent on the trampoline.

Three alloy beams connect the structure, with netting in between. A central pod between the beams will house the outboard and anchor.

Being so light and easily driven the rig doesn't have to be big to make this boat go fast. A typical 3/4 multihull rig will be used with three stays and diamonds on the mast, along with a gennaker flown off the prod.

The existing boat 'Hard Drive' has proven very competitive, and has competed successfully in many Auckland and Coastal races.
