Ron, I would venture to say that if you use the hold down line (tied to the gooseneck) you move your attachment point ever so slightly down. When you tie the loop under the spreaders, your attachment point is above spreaders (the loop is most likely longer than the circumference of the mast). When you tie it down to the gooseneck, you probably pull it down a bit. usually the centre of gravity of the mast is around the spreaders, so moving it even 10-20 cm up or down can throw the balance off.
If you use the tie down line (I do, I have a double spreader mast), that line is there to make sure that the loop won’t move up the mast and it should take the weight of the mast only when the mast is vertical. If properly tied, that tie down line, should not make any difference to the overall balance of the mast. If you find that the mast is unbalanced (top heavy; any other minor imbalance is not such a big issue), you may consider tying the loop above the spreaders (and holding it down with a tie down line to the gooseneck). I hope, I make sense Marek ------------------------------ Message: 2 Date: Thu, 9 Jan 2014 09:06:29 -0800 (PST) From: "Ronald B.

If the load is transferred to the gooseneck (or some other lower spot) by the hold down line, won't that also transfer the "pick point" to that location as well? Doesn't the loop just become the rotation point? ?That would explain my dilemma with the balance when I tried that method. ?If not, what would explain my balance problem? Ron Wild Cheri C&C 30 STL
