For all you regatta organizers out there, this was the first year in a long time we insisted that you at least have personnal liability insurance and present proof of such.
As Jake mentioned, one skipper got his boat insured the day before the regatta, which saved him the cost of a new starboard hull.
Although it may seem like it might have a negative effect on the regatta, the vast majority of skippers were happy that insurance was required and being checked. A number of people had let their policy lapse and took care of it before the event.
