1. eliminate concept of backstay tension causing problem. that was really loose.
2. Mast at fractional is too far forward when set further back than 25mm at step ... I am thinking it is impossible to get Max headstay tension and length unless at min step set back.
3. continue to wonder why most of the comments in these two threads talk about the need to change factory positioning of the step {Production line error? or just not enough feedback in the manufacturing run}
4. remember that the original j24s were based on launching spin from bag ... what we are seeing, I'm thinking, is that engineering 30 years ago ... was winging it by today's sophistication. dito need to template keels.
5. is there any advantage to being set at 40 mm which seems to be the max set back over 25 mm which seems to be the min set back?
6. the races that killed me this week were talking VMG speeds of ~3 kts. real light wind races.
