Lads,
Thanks very much for all the advice, and I will follow it.
I was thinking of putting it in front of the Hand rail, closer to the drivers seat. There is room, and won't clutter the back of the boat.
Easy for the driver to winch it up if someone is on at the back. and not be in the way.
But as usual, the raider team has come through with all relevant info.
And NETIC, during my research I got to have another look at those three vids you had downrigging around the yellow marker in botany bay. Really got the juices flowing.
Thanks again everyone.
