CAT POWER SAILERS ( PS )

A CAT Power Sailer is a power cat capable of  12 to 30 knots under power and 12 to 18 knots under sail.

These catamarans were designed to be built using the fibreglass panel construction techniques. The method is very simple to use and perfect for the inexperienced builder. All of the developing is done in the computer and patterns are supplied for the female frame formers. Special pre-scaled drawings are supplied for each hull panel making it simple for the builder to laminate all of the hull and superstructure on a flat table. The panels are set inside the pre-erected framework and laminated together similar to the plywood Stitch and Glue method.

This is a POWER-SAILER CAT .. the bias is about 60% power and 40% sail ... the boat can be built as a power only vessel or with the added rig as shown.

As for pure sailing cats; although we have considerable multi hull experience going back to 1961, these days we prefer to leave to the design of 'hot sailing cats' to the experts in that field.  We do now design cruising cats ... If you want a good power-sailer-cat then these Cat PS Series could be your choice.
