Gentlemen, As an adjuster for over 20 years, please allow me to add my two cents. In most cases, if you review your own Homeowners Insurance policy, you will find that under the Liability section, your beachcat is covered. This even includes for a racing event. I would refer you to your individual policy and or contact your agent. If there is coverage, then your Insurance Company would owe you a defense for any claim and or suit that results from an accident, and or occurrence. This woould include the reatining of an attorney all the way through trial if needed.
