"Of course, I don't have any of the serial Nos"
I have all my serial numbers after having suffered a similar fate some time ago, it only takes a few seconds to note them, so no excuse! I'm not having ago at you Brian, but how on earth do people expect the Police or anyone else to find things like that, without a serial number how could you prove it was yours? Ok they could take off the serial number, but most realise peple don't note them, and without a serial nyumber it looks a bit suspicious.
Perhaps a lesson can be learnt by everyone here to note serial numbers of such items, that way there is a very, very slight chance of getting the ba...rds that steal other peoples stuff.
Even up to date pictures of your Rib will help, that could be posted for example here. A lot of people are of the opinion that it will never happen to them, and when it does it's too late.
A lot of people wouldn't be able to tell you what was where in their house, if they were broken into, and what had gone. A photo of each room helps, even with the insurance company who may just want confirmation of that antique clock that was stolen! With digital cameras it is very easy, as long as you download the pictures, just in case the camera goes!!
Even some kind of identifying marker, like those ultra violet pens, write your post code or boats name under a seat, inside a locker, or engine cowling, something like this aids recovery of these items slightly.
