Decribed in a single word; stability. One reason for the stable nature of the flat bottom boat is in the deadrise or lack thereof. Generally speaking, a sharper deadrise without the correct counter balance generates a tender feeling vessel which rocks from side to side while at rest. Think about standing in a canoe and doing a few dozen jump jacks.
The Boiler House
The simple boiler is like a barrel, consisting of a cylindrical steel shell, with the ends closed by flat steel heads. It is partly filled with water and then sealed, after which a fire is started beneath it. The fire and hot gases rise around the lower outside of the shell, the heat being conducted through the steel into the water. This heats the water on the bottom of the boiler first. Hot water being lighter than cold water, it rises, while the colder water in the upper part, being heavier, sinks down to replace it and is in turn heated.
