Surely the angle of the wire? A low hook gives a narrow angle, a high hook would give a bigger angle, need to do a drawing.

Your drawing is a thing of beauty, and in itself perhaps justifies the existence of this entire thread.

But it also demonstrates that in terms of mechanics it makes no difference where the hook attaches to the sailor, except in terms of their comfort.

Hook height (on the body i.e. crew always horizontal) makes no difference what so ever on a dinghy, the CoG of the crew will be the same.  It is different on a windsurfer as the mast is canting to windward.

I spent a lot of time drawing it on a special computer programme you should keep a copy it'll prabably be worth lots of money when I'm gone.

As to the physics of it, last time I tried to pull a lever, it certainly helped by standing further away from it than right under it. I'm not proposing this, I'm simply asking the question.

If not, why not.

If that were a static boat in the boat park and you wanted to pull it over, surely you would use the wire and walk further away, would it not be easier?

Surely it's why tall sailors have more righting moment than short sailors because they extend the base of the triangle.

Therefore it must make sense to extend the hook as far up the body as possible if you're short of that body length?

Imagine lying on a plank with no wire, you would still have same effect.
