 Do many long cable pulls

 Do many long cable pulls with winches when you were a sparky? The more wraps the less effort required by you and the more useful the winch is.

Typical RTIO employee

Typical RTIO employee response.. Too hard ?get a contractor in to do it. That keeps me in a job but in the long run raises the cost per ton and then people lose their jobs. When your mate loses his job you can blame yourself.

 More surface area = more

 More surface area = more friction = more grip on the rope.

 Bloody hell i pull my pots by hand, i dont belive anyone should be allowed to pull pots with winches it makes it to easy, kinda takes the sport out of plucking Crays from a box.

Yep, more friction

 You are working with constant slip with a capstan, more turns, less slip. Especially with the highly polished s/s type. Want to see some real grunt, get as many turns as you can on the capstan on a hydraulic winch. It was our default action for snapping them off when all else fails. And Mandurah Matt, you can fuck off, sir . or are you using those plastic pots??

 If you want to see some

 If you want to see some grunt, go for a sail on a large ocean racing yacht and see the power in those winches.....

If you use heavy weights in your pots winches, are a god send, if you are getting on in age, winches are a god send, if you put your pots in water over 12 metres winches are the only way to go.

Enough said
