Our club (MHRA - www.catamaranracing.org) is incorporated, and is fully insured (not through US Sailing, we found it cheaper to buy insurance on our own).

My point is that our insurance policy is essentially a flat fee. If we add a regatta or subtract a regatta our yearly premium does not change. Same as if 10 people or 100 people show up at each regatta. Obviously, this is a problem as our turnout is in decline - the same fee gets spread over fewer people.

Interestingly, if MHRA merged with another organization of a similar size, the same insurance policy would cover both. Thereby, the insurance cost per event is essentially halved.

Perhaps if we joined NAMSA and got our insurance through them, the same economy of scale would apply, hence my question.
