I wonder if more Hobie 20's would come to distance races if they had a spinnaker.

Or would making the spinnaker class-legal destroy the current Hobie 20 one-design class?

Hobie 20 sailors could add spinnakers to their boats, at least to use for Portsmouth racing, just as other classes have, but I haven't heard of many doing that.

Whoops, Dave's post beat me to it about it destroying the existing one-design class.
