...sad story....sorry to hear about your loss
this past summer I had my dinghy stolen from the Marina...(

..and my boat wasn't even runnin ...overheatin' problems..) but I was pizzed off, especially since it was a gift!!..I buzzed around the Marina letting everyone know " SOMEBODY STOLE MY DINGHY " and I WILL be on the lookout!!....well the craziest thing happened....someone turned it in to the Harbour Master...and even left note as to who's it was....
..now I'm just happy I got it back, and asked only once who returned it...but with no reply, I left it at that.... I was just happy to get it back...
..I don't really see this working for you, but sometimes weird things happen..

...Good Luck with its return, if not you've been schooled

...Lock and Key, works for me!!..
