Terry,
I notice you've got the traveller dropped a good few inches. This should be the last thing to go when you're trying to trying to depower. Get everything else pulled in like Eric suggests, especially the downhaul - go mad on that.
Sailing unirig, you should be able to out-point the sloops (although you won't go faster in that weather). Judging an entire weekend's sailing by a one photos is obviously totally unfair, but it looks/sounds like you've depowered to the point that you're close reaching up the the course in order to get boat speed.
Nothing like unsolicited advice, eh? <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
