Unless he has worked on a Belize
genoa and recorded where the marks are, he won't know any more than me.
I have worked out that the genoa is 130% based on measurements and calculated where the marks need to be for a smaller percentage sail. ( 115%, 110%, 100% 85% etc). The problem is that the Belize manual sail plan gives reefing instructions for the genoa by referring to "the first reef mark", "the second reef mark" for various wind
speeds. Nowhere does it say whether the "second mark" is 100%, 90%, 85% or what!
If someone can tell me where those marks are, I will know the FP recommended sail plan (and can work out what percentage of sail that represents.)
(I'm guessing that they will likely be 110% and 85% based on the full 130% but would like confirmation)
