student1: What physics topics can be discussed concerning power boats?
I am working on a physics project in which I have to discuss different topics (in physics) that deal with power boats. I can go into detail on the friction of water, velocity, etc., but I was looking for more in-depth details and more interesting concepts. Physics is not my strongest subject, so any intellectual information would be helpful.

Wow, there are several. Divide into stationary (static physics) and moving (dynamic physics)
(Static) Why does the boat float in the first place (see Archimedes principles) — the weight of the boat will equal the amount of water it displaces (fresh water and salt water are different)
Static) How much water can you hold in the bilges before the boat sinks (reserve buoyancy)
(Static) How does shifting weight in the boat affect trim? In other words if you step onto the extreme edge of a small power boat, you may cause it to roll over, fill with water and sink. (Center of gravity versus center of buoyancy)
(Dynamic) How much energy would it take to move the boat? (lots of factors here) There are two types of energy in play (propulsion and resistance) And in the resistance there are two major types of resistance (surface friction/water against hull and wave resistance)
(Dynamic) what is the theoretical maximum hull speed of a boat due to resistance. What happens when a significant amount of propulsion is applied to overcome the maximum hull speed? (It rides over the bow wave and begins planing — significantly affecting resistance)
