Have a look at the photo of the bottom first. It's obvious water has got in to the ply. At the very least it would need drying, epoxying and glassing. (and probably all the tape replacing)
That said - it's a lot cheaper than a kit, but would need to be looked at before spending proper money on it.
Hmmm, Norfolk to Weston and back is 540 miles = 60L diesel = £80 ...
