I would plot, not that I have as of yet, ALL the jibs in inventory with different reef options too. You may find a 130 and one reef in some wind conditions is faster than say a full main and 110 if the SA numbers about the same area. Then also look at the wave conditions too. I remember reading and article in Sailing World interviewing a skipper in a V70. They had three sail options for winds in the 40-50 range?!?!?! depending upon what the wave sizes were, and where the wind was in relation to the water level. Granted in our little and way under info' we have for wind speeds, waves, where the max wind is etc. still plotting the different sails in even the 20-35 range could be worth doing. Yes under 20 maybe the BIGGEST sail(s), but at 30mph, I know I do not have a 155 and full main up. More like a 110 and a single reef, Or if I get an 85% FT jib, then that and a full main. So which is quicker better in what conditions would be worth plotting IMHO!
