Good Luck with the detectives Air Time.......
For everyone else. I've talked to my boat and home-owners Ins companies. Boat policy covers items bolted to the boat and pre-determined amount of gear based on what amount you choose. (most are about $1,000 and are for items ON the boat like fishing gear)
Extra items not in/on the boat would be your "personal property" and covered under your home-owners policy right.....WRONG! Mine has a $1,500 limit on boat or boat related items. Air Time's apparently is $1,000.
I have extra drives, props, pumps, etc in my garage and neither co covers these items over the $1,500 max my home-owners will cover. Home-owners Ins co has no provisions to even buy the addl coverage and am waiting on the boat ins co to see if they will write something to cover this type of loss.
