You know its funny, with as much money as we spend on our boats throughout the year for maintenance and updates, why not spend another $150 in the event that an accident happens and protect yourself and your boat. Now I'm not excusing the jerks out there who think that they can barge at the start line or rub "A" mark and the outside boat on a tight rounding and not do cirlces, but I think if its an accident, a miscommunication between skipper and crew, or something to that effect then insurance can take care of it. If its unsportsmanlike, other sailors know and see what's going on and most of the time wont let it happen again.
