Hi all, I know this boat well, the OP has had the bottom of the boat replaced, not over-plated.
Effecitvely everything below the gunnel in the picture in the advert is new, only the cabin sites and roof are original - and even they were changed and parts replaced - the front hatch door for instance.
The cruiser stern was rebuilt from scratch, new engine bearers and swim plates etc.
I agree the original wording may need improving as it could be ambiguious/unclear, just trying to help clarify !
The original boat was built by "ARCRITE" - Length 10.98 metres (36 feet ) - Beam 2.08 metres (6 feet 10 inches )
Metal hull, power of 15BHP. Registered with British Waterways number 69628.
Although no date is recorded or known, probably late 1980's...
