I was going to enter a regional one-day Ensign regatta near where my elderly dad lives, so that my son and I could take him out for a super mellow day of lake racing, thinking that'd have been fun for him. I found a fellow who would be happy to loan me his boat. When I sent in the entry form, I got a rather snooty response:
I understand you wish to sail a borrowed Ensign to sail in the Fleet [ ] Regatta on [ ]. Please note that the regatta follows the Ensign Class Association rules for regional competition, which require that the participating boat be sailed by bona fide Ensign owner.
I would suggest putting a list of dates together that your family would be available for Sundays and I will forward to our members who would be willing to take your family out to participate in one of our club races.
Is this common? If so, why? I have never heard of a class that cares whether or not you actually own one of their boats -- most groups are happy for whatever additional competition they can get. In my experience, anyone who can get their hands on a J24, Laser, Viper, Thistle etc. is more than welcome to sail it, no questions asked. Most people would say, the more boats on the line, the merrier.
Why this silliness? Who cares?
