I know this is a very old thread, but theres a little bit of progress been made. I was out today at the sailing club and managed to speak to the guy that used to have access to the shed in which the canoe is. The shed has changed ownership recently, and all of the boats inside have had the names and contact numbers of their owners taken down. I'm going to see if I'm able to get in contact with the club that now owns the shed and perhaps find out the owner of the canoe in question as it is still there according to the guy I know
I'll post updates if/when I make progress.
