J/30 Class Association Forums J/30 Forum Racing Tools and Techniques symmetrical spin vs asymmetrical spin

would love to see a photo of A on a 30 to get a feeling for what it looks like ... see photo next column under bird to see a 105 vs j30 with wind on beam. Am thinking I would like to attach it higher than the fractional point on the 30

for Phrf we carry .75 and .5 if there is any hint of light wind ... under 10,

but for marcho days we have an old 1.5 oversize.
