Here is the response from my insurance company:
I will need the following information to process your claim:
Your signed statement: providing a brief description of what happened, the name, address and phone
numbers of the driver, as well as the date, time and place it occurred (body of water
or roadway, zip code of the nearest town). Please submit a copy of any government
report (police/sheriff/fish & wildlife, etc.) that has been or will be filed. Lastly, please confirm your Lien Holder for the boat if there is one.
A written bill from the towing/salvage company.
Please feel free to contact me with any questions that you have and I will let you know of any additional information that we need after the above items are reviewed and keep in mind that any storage
charges are not covered by your policy (Part E item 2g).
