WebIt is the relationship between centre of gravity and centre of buoyancy that dictates the righting moment. The advantage of water ballast is that the tanks can be emptied, reducing draft or the weight of the boat (e.g. for transport on ground) and water added back in (in small boats, simply by opening up the valves and letting the water flow in) after the boat is … WebDec 13, 2015 · While righting moment if obviously important to good sailing performance, this is another area in which is it possible to have too much of a good thing.
