Introduction of revised Board Correction Formula
A new board correction (BC) formulation has been created to fix an anomaly in the previous formula, which has only become a problem now that very high aspect ratio boards are being used on some boats. The previous BC correction started reducing again for a board aspect ratio greater than 5, due to its quadratic nature. The new formulation is asymptotic such that it continues to increase and tend toward a final value for very high aspect ratio boards. The new formulation has very little effect except for boards with aspect ratios of 5 or more. The proposed formula is BC=15-15/(XB^0.1045)+2. XB is the aspect ratio of the board, there is no penalty for larger boards, just for the aspect ratio, which reflects efficiency.
A new method for measuring the length of the board (VLB) has been created this will give a very small penalty for curved boards, where depth will be measured around the circumference. It will also give a small penalty for T foils, as the length of the horizontal section will be included in VLB. This is an interim measure. A full review will be needed when and if curved boards and T foils start to show a significant and consistent advantage.
