Mainly ease of manufacture and operation. Airplanes with propellors in the back are generally more efficient in the overall drag and lift of the airplane. However, it is much easier to place the propeller in the front and the engine in the front as that helps with the Center of Gravity. Also placing a shroud around the propellor, just outside the diameter of the tip, will also increase the effeciency of the propellor. The more effiecient it is, the less power is required and the less fuel is needed or the engine can be made smaller. A propellor in the front of the boat would disturb or disrupt the water flowing around the bow. This would make the boat bump more over the waves it would create. Also a propellor in the back of the boat provides some protection in case the boat should hit something floating in the water.
No, the propeller will only work if the engine is running.
Yes the 'bow' is the front of the boat and the back of the boat is called the 'stern'. bow is in the front its the ponity part of the boat, the stern is all of the back of the boat.
Bow is the front of a boat and back is called stern.
The propeller.
Prevent Propeller Strikes
A rubber band boat works much like a rubber band airplane. First you need to build the boat itself. Then you need to make a propeller. The propeller shaft needs to run through the inside of the boat, not below the boat. With the prop below the water. The propeller shaft should not go the full length of the boat. About halfway through put a loop in the shaft. Then to the front of the boat attach a rubber band. Then run the rubber band through the loop in propeller shaft. Now twist the prop and the rubber band should twist around and around. When it's good and tight let go and the propeller should spin. Allowing the boat to move forward in the water. Mind you the shaft needs to be a thin piece of metal, as it will be difficult to make it water tight.
No, the back of a boat is called stern, bow is a front of a boat.
Back of a boat is called stern and Bow is the front of a boat.
the propeller turns and the boat goes
On a boat, when you are facing the front (the Bow,) the Stern is at your back.
Prevent propeller strikes.
