Design Number 217 (Composite construction E-Glass and PVC foam)
Here we have a power catamaran where the power performance has been
the main determining factor in the design. Though no attempt has been
made to produce efficient all round sailing in all conditions she does
have plenty of stability to stand up to the sail plan. When the conditions
suit and the schedule allows, the sails will provide silent propulsion.
At many other times the sails will combine with the engine power for some
really good motor sailing speeds. The important factor in the design have
been practicality. This approach has brought us to a style which works and works
well, rather than attempting to fit the layout to a particular style.
To truly attain the 'best of both worlds' is rare. When the objective
is to combine sailing with good power performance, the catamaran configuration
comes close to it. The widely spaced, slim catamaran hulls provide the stability
to carry a sail plan and the slim hulls provide low resistance and good sea-keeping
qualities for performance under power. Some compromise obviously applies. The weight
of engines and fuel will slow the sailing and the weight and windage of the rig will
affect the power performance but to a lesser extent than the typical motor sailer mono.
The Power Sailing catamaran is perhaps the best way to get around on the water
efficiently and be able to enjoy both speed under power and sailing.
We have designed a few larger cats and tris but this is the first in this style.
The project brought Derek Kelsall round the World to New Zealand over 10 years ago.
