How many sq.m is this sail? What is the mid girth measurement? What rating rule are you sailing under and how does this sail affect your rating? I am looking at adding some large masthead kites to my 105. I am interested to know the performance gains.
I am wondering what the average J 105 Spin size is on the European boats that do a masthead hoist? I would assume most would be designed to IRC rating benefits but I would like to know what you guys are using and benefits. Also has anybody tried to redesign the rudder to a more efficient foil as opposed to the barn door they came with?
