Mark,
How much is a spinnaker going to cost for the corporate entrants?

Are you going to require all 12 to be made by the same loft? Do you know what loft you are going to use?

And at the end of the season, does the corporate sponsor of the spinnaker get the spinnaker back, or does the owner of the Ultimate 20 that it was used on get to keep the spinnaker -- part of the payback for use of his boat?

Or do you keep the spinnakers for use in the next regatta?
