this is not always the case.as a boat moves through the water it displaces the water in the space where the boat is. as the boat moves faster and faster it must move the water out of the way quicker.since it pushes the water faster bigger waves are produced. push your hand flat through the water slowly to displace the water then do it quickly.see the diference in how much you disturb the water? now heres why faster doesnt always produce bigger waves.some boat hulls are designed with a large portion of the hull below the water surface. they are generally heavy ,can carry heavy loads and are designed to run efficiently-move all that water out of the way at relatively slow speeds with moderate use of energy-reasonable fuel consumption. they make big waves when pushed faster. then there are planing hulls that are designed to go fast running on top of the water or even on a cushion of air that is trapped between the hull bottom and the water-the faster they go the less water they have to move or displace and the smaller the waves.now if you run a planing hull too slow to truly plane-rise up fully so that there hull can function as designed that big flat hull that was designed to plane can displace and push a tremendous volume of water very fast.big waves! of course there are other hulls called semi displacement-same principles apply. move a large volume of water quickly=big waves. hope this helps. enjoy your time on the water and be safe.

They displace the water faster as they move faster. If they are moving slowly the water can compensate for being displaced by spreading out around the boat. If the boat moves fast the water can not even out around the boat quickly enough so waves are formed.

They dont. They are up on plane when they are going fast (less boat in the water) thus they displace less water. The worst waves are just before the boat planes.

They don't. They make big waves when they first get going because they are pushing the water out of the way to get on top of the water. Once they are going fast and are on top of the water the wave is small.

Because the moter is moving faster your going fastier which makes the waves get BIGGER

They don't. As said above, less boat in the water = less wake. Worst wake is just before the boat gets up on plane.

friction with water due to the weight of the boat,speed and
shape of it obviously has an effect on water making it split and form this waves you talk about

The same reason stronger winds make bigger waves.

they move more water

because they have a bogger propeller
