Hi I had a 100 % blade from One sails on my 325, hi tec material with leech battens hanked onto the forestay. It sheeted onto the coach roof. Upwind in over 12 knots of wind it was brilliant and short tacking up east coast rivers easy.
However below 12 knots very underpowered. The worst thing and why I replaced with a 135% Genoa (also one sails from John Parker) onto a furler was the complete lack of power on all points of reaching. I really needed to use the assymetric but am generally too lazy!
I don’t carry the blade at all and seldom miss it. The Genoa is fine upwind and effective reefed with a couple of rolls. I went with 135% instead of 150% as it reefs to the size of the blade and still works.
Hope this helps.
Doug
