The biggest problems with DAN insurance are (and these may also to apply to others, I don't know):
I'll stick with scheduling my gear on my homeowner's with a pre-established value, all risks, worldwide. They're going to be the first payee anyway.
- DAN insurance is secondary to any other existing insurance, so your going to have to use your homeowner's anyway, at least to the limit that it will pay.
- DAN issuance is the sole determiner of the value of your loss, there is an "appeal" process through appraisals, which you have to pay half of.
- There is an "inherent vice" clause ( INHERENT VICE is a loss caused by the inherent nature of the thing insured and not the result of a casualty or external cause) which means that they could deny a claim for a flooded item based on the fact that flooding is an "inherent vice."
- Consider these two items together: excluded is unexplained loss, mysterious disappearance or shortage disclosed upon taking inventory; as are items lost while in your care, custody and control - while in use both in and out of the water, dropped overboard or swept over-board.
