Zeta is another of my small, hard chine plywood trimaran, but this time it is a fast singlehander with the emphasis on being as simple and quick to build as possible.

The photo below shows my own Zeta on its maiden sail off Port Townsend, Wa, USA

and then here, finished, with optional screecher.

The hardchine hull is similar to the Zest and Duo dinghies, while there is no cockpit tray, as used on the Strike 15. The photos below show the first Zeta being built in the UK.

The outriggers are simple Veed hulls for easy building. As with the Strike 15 the intention is to have an active crew stabilising the boat, so that the outriggers are generally clear of the water - "training wheels" if you like. (Photo actually shows Tryst outriggers, but Zeta is similar)

The beams simply slot into the main hull and are joined on the boat's centreline. They are normally permanently attached to each outrigger, but can be unbolted for long term storage. So it is still a fast setup, especially as the dinghy skiff style mast can be left up even with the outriggers removed. Very useful if keeping the boat in a dinghy park or storage area. A jib and a screecher are options.

I show how light the boat is in these two photos, first the main hull and then the outriggers

The main hull weighed 43kgs (95lbs), each outrigger 11Kgs (24lbs), all four crossbeams 8kgs (18lbs) So a total weight ex rig of 73kgs, (160lbs)

... and here is one with a home made screecher

Although it is always easier to trail a boat rather than car top it, it is possible to out a Zeta on the roofrack of a large car. The sketch shows the idea. Two wide roof rack supports, the crossbeams can stay on the outriggers which speeds assembly. Obviously the same concept applies to a Zeta on a trailer, or even when stored in a dinghy park
