Brecksailor,
We thought the same thing and never bought trip ins. For some reason our whole crew did for our 2014 trip. I went into Afib a month before the trip. My husband is the captain so we had to cancel the boat and all. Everyone was paid in full and that was a relief. We used AIG on that trip. Now we would never book another sailing trip with our trip ins. Way too much money to waste!
