I haven't been easing the traveler in a gybe - but I'll certainly give it a try. It makes sense.

Coming through a gybe with fresh breeze as I heat the boat up, it really feels "bound up" for a few seconds and although we're flying a hull, the boat doesn't REALLY start getting back to speed until some time passes and I've steered back down slightly and the hull lowers a bit. This certainly could be attributed to the main being stalled until the spinnaker propels the boat enough to bring the apparent wind back to where it was. I've never really thought about it (or had the spare effort to look up at the tales during the manuever)

Thanks Dan!
