Stacks Image 140


Produced on the same lines as the wonderfully successful “ Henley ", the "ISIS" is capable of good speed and is a splendid replica of the modern high speed motor craft. The propeller has been very carefully designed to give the highest efficiency and the shaft has been fitted with 2 ball thrust bearing to eliminate loss of power at this important point.

Design

So simple a design for simple construction. Made from mahogany the huls was painted on the outside with green and white colour scheme, althoug the wood is so nice some have stripped it down and varnished the wood. A flat bottom with simple rounding. Flat sides bent to fit the bottom. A flat stern deck and a curved fore deck. Plenty of width for the wide boiler and to provide stability the construction allows plenty of room. A steeply angled propellor tube is not the most efficient. The ruddeer can be set to alow the boat to steer straight accross the lake or to circle back to the owner.
