Thanks Wouter,

As usual a very thorough answer. You have given me plenty to think about and to practice.

One query though:

>>Best way to round sound is wait till you're scared as hell. Drop is quickly and possbley a little low to the mark with the skipper staying in the trapeze or not depending on conditions on the expected upwind leg.<<

On a usual marks to port course the above scenario would require dropping the spi while on a port tack. Our boat is set up with the bag on the port side front of the trampoline so that we launch it after rounding the windward mark (to port) on a starboard tack without needing to jibe first. Is it possible to launch and drop the spinnaker on a port tack with the bag on the port side of the boat? A bag on each side perhaps?

Rob.
