Thank you all for your advice and comments from your experience. I have been sailing the boat with an asymmetrical kite from a deck mounted sprit and a 140% Jib. I have got some inputs, including from North, to the effect that, in our Santa Barbara conditions, the boat would perform best to handicap with a symmetrical kite and (up to) a 155% jib. I will tease this out a little further. Further comments would be much appreciated including inputs on pole length.
