The TC 10 is a performance Cruiser/Racer catamaran featuring a large sheltered cockpit with wrap around dodger.

The rounded hull and deck shape flares into a chamfer panel and cockpit seats inboard, to increase interior space. The curved rear beam extends from the rear seats, and the main beam also fairs into the hulls, to produce a very modern, integrated form and structure. A spray rail runs the length of the hulls, both to keep the crew drier and provide lift at speed.

Accommodation includes two double berths aft, that each converts to a dinette, and two singles forward. The Galley is amidships to starboard while the navigation and head are to port. The rear berths have a large hatch in the rear bulkhead opening onto the boarding platform to give good ventilation and light below, which can stay open in most weathers at anchor.

The spreaderless mast is either an alloy section or a stressed plywood carbon wing mast. The mainsail is boomless and the jib is self-tacking for safety and simplicity. The mainsail sheets to the curved rear beam. The gennaker and fractional reacher are flown from the retractable prod.

Steering is done either from the tillers aft or the central whip staff. A 10-15 horsepower engine is mounted under the central control pedestal and winch, where all of the halyards tail to. Sheet winches are behind the helmsman in the cockpit. The boat is easily handled by one person, and usually crewed by 3 for racing.

Tim Clissold's own boat 'Pulse xTC' was launched in 2001 and has since cruised and raced 5000 nautical miles around the Hauraki Gulf and beyond.

TC 10 - UNDER CONSTRUCTION:

Although I have designs for both Plywood and Strip cedar construction, Foam sandwich composite seems to be the material of choice at the moment.

It produces a light weight, well insulated boat while being simple to build when using the right techniques.

By splitting the hulls down the centreline and setting up the moulds on their sides, access is easy to all parts of the catamaran hull. When planking the hulls, foam is added down to the spray rails, then the interior laminate is added.

This way the builder is standing on the floor for the first part of the lay-up. Then the remainder of the foam is added, below the spray rail. The builder can then stand on the fibreglassed topsides to fibreglass this area.

The interior (plywood) can then be nearly completed before the halves are joined, which saves a lot of time due to the easy access to all parts of the hull half.

On smaller designs like the TC 10, the interior can be taken to topcoat paint before joining the halves. This minimises the work to be carried out in an enclosed space.

Beams and hard deck are plywood, cedar and foam composite, with carbon in high load areas. This gives a cost, time and weight efficient structure for a modern high tech boat with no vacuum bagging.
