All,
One major problem that no one has addressed yet is UPPER BODY STRENGTH! All these furlers, etc, still require 2 hands and then you have to get it down and on the boat (windage) wasting yet more boat lengths in a race. Furlers are for cruisers, IMO.
If I can say this on the forum, I had a very slick and easy system for retrieval on my F17. I could outperform 99.9% of the singlehanded spin sailors out there in the hoist and drop. I have pics somewhere on my computer if anyone would like to view. The 2 line systems talked about simply means you have to do one more movement again wasting valuable boatlengths without the kite up and sailing. Don't ask me how I know!
