Close enough CAT. They were sandblasting a barge on the slipway in preparation for a re-paint. Over to you.
A working slipway constructed in 1838 to improve the repair capability of John Smeaton's 18th century harbour. The design follows Morton's patent.
The ramp is 40ft wide and measures 300ft above low water, sloping at 1:16. It is constructed from granite blocks and topped with three sets of double rails, 11ft apart. Along these runs a wheeled cradle which can bear weight of up to 500tons.
The cradle was originally worked by a manual capstan but this has been replaced with an electrically driven winch.
