@dave2ball @skierjp: In anticipation of promo boat shortages, I had my personal boat insurance for 2020 endorsed to provide coverage while being used in USAWS sanctioned event. I already had $500k liability coverage (I believe everyone should have that much or more anyway), and the endorsement did not cost one penny in additional premium. I had to request this endorsement by letter to the company, and I am not completely satisfied with the way the endorsement is written. But, I do believe that it provides coverage while my boat is being used in an USAWS sanctioned tournament. My boat hasn't yet been used in a tournament, but I will keep the extra coverage in 2021.
