## What boat design can hold the most weight?

Wide, flat-bottomed boats will hold the most weight.

## What is the most buoyant shape?

The chances are that the flat-bottomed shape you made was the most buoyant, and that’s because it has a larger surface area than the other shapes. More of the foil was in contact with the water, which means that there was more water underneath it pushing up on it, so it could support more weight before it sunk.

## Why do foil boats float?

The foil boat has less density because it is spread out and filled with air. Things float when they have less density than water, but sink when they have more. It’s the same thing that happens when an anchor is placed in a boat. Because of buoyancy, boats can carry objects that won’t float on their own.

## What is the Penny boat Challenge?

## How much weight can a boat hold before sinking?

Water weighs 1000 kilos per cubic meter. So, if the box weighs 50 kilos, then you can load 200 kilos into that box on water before it will sink. If you only weighed 120 kilos, you could paddle around the pond in it. In brief, a boat will only sink until its weight “displaces” the same weight of the water it is in.

## Can wood float on water?

If you compared the weight of wood and an equal amount, or volume, of water the sample of wood would weigh less than the sample of water. This means that wood is less dense than water. Since wood is less dense than water, wood floats in water, no matter how big or small the piece of wood is.

## What has to be true for an object to float?

An object floats when the weight force on the object is balanced by the upward push of the water on the object. If the weight force down is larger than the upward push of the water on the object then the object will sink. If the reverse is true then the object will rise – rising is the opposite of sinking.

## Does crumpled aluminum foil float?

The crumpled wad should float and the compact, folded aluminum object should sink. Water has a density of 1 gram/milliliters and a solid piece of Aluminum has a density of 2.7 gr/ml. Your pieces of aluminum foil have about the same mass (since you tore your original piece in half).
