REPLY Remember that a weight hanging from a mast will have the effect of that weight located at the suspension point. Hence the great heeling moment of even a relatively smaller weight. ( compared to keel ballast) However, the lateral movement of any suspended weight is significantly lowered compared to moving that same weight directly. The lenght of the hoisting line is like a pendulum arm. Spinnaker poles would be sufficient to push out even a 2000 pound weight a distance of only 10 feet when hanging from a 50 foot or higher suspension point. As an example , the inner ends of th epole could be pulled out towards the railing with a block and tackle similar to the tackle controlling the end of th eboom. Hook one end to the toe rail whic hoften has attachment points for the jib sheets. The other end is hooked to the inboard end of the spinnaker pole. Fore and aft guys could be used to control any fore and aft movement of the weights pushed out by the pole.
