Paul and Wouter,
The F16 is just insanely fast off the wind.I only concern myself with the proper angles and not slamming into what appear to be stationary objects (non spin boats), when sailing downwind.

We're at an important juncture with the wing masted solo F16's in that the old Taipn 4.9 advice to foot and go for speed to "A" mark is no longer fast.The new generation F16 mains (atleast my Glaser),can sail higher than anything except the Acat and best VMG is definitly achieved by sailing high and just short of pinching.My problem is that in light stuff lots of downhall and light sheeting is slow in even small chop (just no power in thesail).Additionally, the fact that the mast rotation cannot be seamlessly rotated into the luff curve of the sail says to me something is wrong with the cut of the sail and wingmast synergy.

If I could set the wingmast and sail luff curve properly, rotate for a bit more power, keep downhall moderate and have the power to plow through chop that'd be very fast.Slackening the diamonds with the innovation pictured would give me more draft in the middle of the sail and the proper rotation etc.

If this is wrong thinking,please chime in before my drill battery is charged!
