Welcome to the UKWA Home Page Forums Technical Missing buoyancy? Re: Archimedes’ messenger not shot. (yet)


Purely because I’m enjoying the scientific discussion, not because it is hugely relevant, I’ve been thinking. The principle of flotation is that an object will float IF the weight of the water displaced=weight of object causing the displacement. It does not infer that if you make the object heavier it will displace more water and float. The heavier the object, the more water it has to displace, this being due to the relative densities of water and the object.

So, if you fill up your storage bottles with water, you are increasing the density of your boat without increasing the amount of water being displaced by a similar amount. Also, vector in the fact that whatever the buoyancy in the tanks of a wayfarer, they need to maintain a density less than that of water to maintain positive buoyancy.

I think.
