Opsrey 18, one of the very first ribs to be made by Osprey/Offshore Components. Should date from 1988 - 1990 time and was the forerunner to the Sparrowhawk.
Built by Mike and Ralph in deepest darkest Lancashire (bloody impossible to find the first time) as are the latest Vipermaxes. Needs a hatch to access the bow locker for storage.
Buy it, you should be home in a couple of hours in that, done that journey a few times in a Sparrowhawk.
