Macca,
These are good points and I think we're doing this (also loose luff and oversheeting when it's really light to make gennaker camber favorable for apparent wind drives...).When it's windy and choppy I've also : raked the mast aft beyond recommended to lift the bow's , tensioned the retrieval line
to spill some power (i've seen 49er crews do this),wired off of the transom...
I'm just wondering if there isn't a structural/design innovation(adjustable T-foils ,adjustable hull canting,more hydrodynamic lift/planning aspect to hull,flatter gennaker cut...) someone's been considering that would allow us to
drive the boats like skiffs on the kite reaches without compromising the boats easy brilliance to wind.One never knows if one doesn't ask...
