They do NOT insure injury or damage to participants
Most regattas require each participant to carry liability insurance in order to race just for this reason.
insuring only injury to "spectators"
This coverage is included in the Beach coverage of your regatta package. It costs approx 400 more dollars.
Some coastal municipalities force organizers to have "insurance but it is very difficult to find out what they actually want!
The US Sailing insurance or Myers Briggs package will directly name the municipality on the insurance form.
But my wife says we ain't doing it anymore for legal reasons.
Your wife is wise... Why should you take on any unneccesary risk when you can charge every participant 10 bucks for the YEAR! (40 boats, 2 people at 10 bucks a head!)
Insurance should not be stopper for running an event unless you don't have decent numbers of sailors participating.
