When trying to single-hand my H25 ('77), I notice that I am having a great deal of difficulty tacking the genoa (150).To sheet it in I have to use both hands since the winches I have are not self-tailing, and while I am doing this my tiller goes awry.Couple of questions;1 - would a self tailing winch help a lot or a little, and has anyone tried "winchers" as a make-shit solution for making a non self-tailing winch self-tailing?2- my jib/genoa sheets tie off to a dock cleat, and it takes a few seconds to wrap then in .. would a jam cleat be better (Iknow it would be faster), or are they not strong enough when the sheets are loaded?Any advice would help, cause a lot of the time I sail with non-sailors and I really need to handle most tasks on my own.Thanks in advance.
