This one is tricky(for me).

The base block and attachment steelwork is fitted for my mast. the land is sloping quite a bit , forward and aft guy anchor points are not a problem.

Now ,the big question is , how do I calculate accurately the side "point-of-attachment" length from the centre ,say 30 feet out from centre  ?.  The high side is no problem as the ground is level at this point-just drive a peg in at 30 feet.

The other side of ground falls away --is there a easy way to accurately measure and peg the point -of -attachment for this side ?

any takers?

Thanks Bruce
