Boat US has a great reputation
I agree with the above comments that it is worth considering more than premium alone. A few months back I made a coastal trip with a few other boats, and a singlehander who had more time, stayed in an anchorage after the group of boats left, and ended up wrapping his anchor chain around his drive shaft, bent the shaft, fracturing the shaft log. He was able to get back to port, and then, only at the urging of a a fellow sailor, called Boat US to see if any of this was covered, and it was.
When my last insurance policy with Progressive expired, I moved over to Boat US. The agent said that they are trying to cut premium costs for people who don't have a history of making claims. They also cut 10% off the rate if you have taken a boater safety course. While I'm sure there are big insurance companies that give great service, I kind of like going with a boating-only outfit.
Trielly, did your company want a survey to increase the ACR?
