After getting their heads together and discussing what design elements
were required to travel as fast as possible for long distances and still
be able to walk when they got ashore, Simon designed the craft with a
fine wave piercing bow to reduce the pitching moment, he gave it a very
deep 'V' to soften wave impacts with a relatively narrow beam allowing
the craft to pierce the sea with minimal drag. Captive tapered tubes extend
from the 'hard' bow to the stern with an open transom that allows shipped
water an easy exit. The sponsons act as buoyancy and also to keep water
on the deck, (holding that area of the craft down as it makes its way
to the open transom.) The air trapped between the sponsons in the bow
area also helps to blow the top out of the wave as the craft passes through.
This effect was noticed when undergoing trials with the1/5th scale working
model with 5hp power unit.
The model performs superbly and has an impressive top speed of over 50
knots.
