Do you know the foot length of your Genoas?
Original Amel foot is 8,25 m giving an area of 67 sqm. With a J of 5,0 meters I get it to 165%, but I might be wrong in how to calculate the %.
with my way to calculate the foot of your Genoas would be 5,5 m and 6,75 m looks small, am I correct?
Would guess a 50 sqm Genoa would be a good alternative for the Caribbean.
