1. Propulsion
A boat accelerates through the action/reaction principle (Newton's 3rd Law). You move water one way with your oar, the boat moves the other way. The momentum (=mass x velocity) you put into the water will be equal and opposite to the momentum acquired by the boat.
Consider a boat before and after a stroke.
Figure (1.1)
Before the stroke, total momentum p = 0, since everything is at rest.
