K S S  P 6 1

Design Number 203 (Composite construction E-Glass and PVC foam)
Design Description
This design began as a custom design at a smaller size, onto which we applied the accommodation required. The hulls were then stretched by a couple of meters. This is the ideal approach for a serious offshore performer, as required here. We looked closely at the slim hull advantages. Our conclusion is that ultra slim hulls, which slice through the waves effectively can only be applied to ultra light weight vessels. The accommodation has been arranged to allow the bride-deck to be raised forward to give that extra clearance when heading into the waves. Designed for 20-25 kt performance and 2000 mile range. We think the traditional style suits. For KSS construction.
