Hi Scott,

If you are the owner of the 90ft Catana, maybe it would be best if a few of us to come over for a week to help you out with your trimming problems.

I'm not a trim expert but from my experience if the ones on the leach are streaming backwards it means that I'm undersheeting.
Normally I try to make them stream backwards from the bottom of the sail upwards (If the top-most one flows backwards the sail is probably stalled too much).
