As said in your last thread, if there is nothing on the bare GRP right up inside the bows then you won't find anything else. There never has been a "formal" marking as such.
Ah right i see, is there not a certain spot that they all were stamped so I can look I've looked around the floor and peeled back some of the insulation but I don't want to be stripping the whole boat back even more bare than it already is. Or any ideas how I can age the boat as I need to have an age to get insurance but I have no idea what it could be??
Like in other threads, if you cannot find any markings usually just a bit of pencil scribble in the bow under the carpets then look at similar boats to get a rough idea because if you don't know it's sure as hell the insurance company won't know either.
