Free boat at Bowmoor Sailing. In need of restoration. Jib and main available.
The number 60799 is marked on the centreboard in one of the pictures, so I assume that's the hull number.
Definitely a restoration project, but looks doable to judge by the photos.
Contact commodore@bowmoor.com. The club is located at GL7 3DT.
Cheers,
