I saw an ad once for a water-filled anchor that was just the cat's pajamas. Empty it out, it's really light. Fill it up, it gets really heavy. Fill it with fresh water and you have an extra supply of drinking water to boot. The weight of water in water is nothing. In other words the thing will be so bulky that its bouyancy will result in nearly no effective weight. Anchors need to be dense as well as heavy, the weight in the water is all that counts. Casady Uh, yeah. That's a given, I think. |
