OK here goes, I'm feeling vulnerable but....
I'm now thinking that when single handing the F14, I might try sailing the boat with the spi sheet cleated and
work the main with the tiller. In all the sailing I've done with spinnaker [offshore] the main is eased to reduce pressure never the spinnaker as when the kite collapses it just takes too long to reset and too much time is lost, plus if the main is on too hard you can't bear away in heavier stuff without easing because the rudders cavitate. And resetting the main if you're on the wire with the spi sheet and tiller is a tricky manouver.
Most supersloop sailors cleat their jib, and really, the spi on th 430 isn't all that big.
My thinking is that the kite has a sweet spot which is best achieved while sailing a particular heading, if you're looking for best VMG that is, particularly when the reach is a bit shy.
I might add that with the sheet cleated on the back of the dagger board it is failry readily available for a quick dump if necessary.

Now dump on me if you like. <img src="http://www.catsailor.com/forums/images/graemlins/smirk.gif" alt="" />
