i bought a boat and trailer as a 'Norman 18' but not sure this is accurate. I'm not overly concerned but need to change insurrance over to it.
It measures 15.5 feet from prow to transom, 6.5 feet beam. I'd guess a fairly old boat as it has dark mahogany ply woodwork throughout, has the moulded cabin with wooden crew handles and wrap around front perspex windows which i read were later dropped for flat windows. has a round port hole window for kitchen and also toilet/cupboard compartment.
