The Albin Ballad generally runs a 135% Genoa II which has an area of around 25.4-28sqm, the SA/Disp figure mentioned of 16.09 is based on the 105% Genoa which people run when they don’t need to go fast. The SA/Displacement for the standard genoa II is around 18.71.
The line drawing shows a 105% and a 150% genoa.
Thanks for your post. One small correction, the SA/D of 16.09 is based on the information we found on the rig measurements for the Ballad so it’s based on 100% fore triangle.
Some good news… We are VERY close to launching a new, upgraded site. Included will be a calculator where a user will be able to input changes in sail area (or displacement, ballast, etc.) to see how the changes effect the performance ratios.
