The 17 foot Star board has the wide point at 50% aft and a circular arc rocker of 9 inches. This works very well and gives the board the ability to ride inquite a wide range of conditions. For the Sun board we have moved the wide point up to the 40% aft or 'Heart series' position, flattened the tail rocker and given the nose rocker an elliptical section. Rocker overall remains at 9 inches. The effect of these changes is a much longer rail line ( 12 feet of tail instead of the 8'6" of the Star board) The Sun board will be even better than the Star board at catching and riding unbroken swells. The challenge will be to handle the greater length and flatter tail rocker through shorebreaks and other tight situations. Experience has shown us that with the 'Eagle eye' of the rider scanning further into the future of the surfboard/wave interaction, navigating Olo boards of sensible design through such sections is practical.
The rocker jig side pieces are built, the laying up bench is ready and the planshape has been drawn out and cut ready for final fairing. Making the tail section in planshape required a wire compass of about 25 metres in radius.
Here's the planshape:
