PotPot boats flotation and buoyancy.


You may wish to familiarize yourself with the concept of buoyancy before continuing. The potpot
boat floats because of the principle of flotation. This principle states
that: 

Firstly, we need to find out the maximum weight that our PotPot boat can displace without sinking. Step 1  Fill a beaker to the brim with water. Step 2  Place the PotPot boat on the surface so that it just floats. Step3  Place a small measuring cylinder under the lip of the larger beaker so that water, flowing from the large beaker, will run into it. Measure the weight of this measuring cylinder first. Step 4  Gently push down on the boat until the water is just about to flow into the hull of the boat, as shown in the animation on the right. Step 5  Weigh the cylinder with its water content. 

The weight of water displaced is the maximum weight of cargo(fuel) that the PotPot boat can carry. Use the table below to help you calculate accurately the weight of cargo your boat can safely carry.
