Very clear explanation Ian. Last Monday I used the iS105 with OD7.5 in gusty conditions 12 tot 20 Kts. With my weight of 95 kg the iS105 really isn't a good floater

in windlulls. The shallow water was saving me a couple of times

. In deep water, but also for planing through the iS125 with 7.5 would have been the best option to make most fun concerning planing time and about the same topspeed

!!
