There was a fire locally that consumed trailered boats and cars. It did not involve me in any way. Such fires bring to mind the, at times, complicated and potentially difficult process of getting settlement from an insurance company. Fibreglass can be consumed to the extent such that identification becomes difficult. To protect oneself, I think it important to assembled ahead of time documentation of your boat in storage. A signed storage contract identifying location and dates of storage, receipts for storage, and dated photographs of the boat in storage; all I believe would be most helpful in proving a loss. All perhaps obvious, but I have simple cash arrangements for such storage - did it once. Ciao.
