RE: iS145 vs. iS133 in 8-14kts 7.5-9.5 sails?
I thought I did - try again...
8-10 knots - you don't need the 145
10-12 knots - you don't need the 145
12-14 knots - you don't need the 145
Early planing differences will be almost negligible - top speed and control of 133 will be superior to 145 on all points of sail. You can easily get a 9.5 on the 133, so unless you want to go even bigger you don't need the 145
