Octave Development Bearing Fruit

We now have comprehensive feedback on the Octave design.
Qualitative and quantitative tests have enabled us to evaluate the radical features incorporated into the prototypes in order to decide on values for future production boats.

More detailed explanations of the design choices will be published later, but the broad concept has been validated.
Overall beam, prismatic coefficient, the characteristic forward location of the centre of gravity, the piercing bow, and the chambered deck are all retained.
The treatment of the chines has been softened as the volume distribution is maintained, but the water-shedding characteristics of the chines were found to be detrimental in some conditions.

Overall volume has increased, as has the midships freeboard.
Some moderate hull flare has been introduced in the centre section to reduce sink at large heel angles, and the deck height at the mast has been increased to both increase heeling moment and keep the booms clear of the water in rough conditions…

Congratulations to Ray Joyce who won the day this past Sunday in light conditions with the much modified original Octaveprototype.
