How does water move a raft?

Water moves a raft primarily through the principles of buoyancy and displacement. When a raft is placed on water, it displaces a volume of water equal to its weight, allowing it to float. As water flows around and beneath the raft, it creates pressure differences that push against the bottom and sides, propelling the raft forward. Additionally, currents and waves exert force on the raft, helping to move it along the water's surface.
