General Information on Barton Tackle
This tackle arrangement using the fiddle swivel becket cam and a fiddle swivel block will give a quadruple purchase. They can be supplied with or without adjustable angle cam locks. A useful general purchase tackle for raising outboards and dingys but more commonly used as a mainsheet arrangement. In my opinion suitable for yachts up to around 35ft.
