I'd emphasize that this is one of the best races to get started in the distance/endurance type racing.
Protected waters, easy logistics, and straight line sailing.
Might reach out to some of the local youth programs to see if any are interested in stepping up... heck, some of those 420s and laser radials rate about the same as an H16 non-spin, right?
might increase entries and lure some to the dark side...
