No, water molecules in a wave don't move horizontally. In a wave, water molecules move in a circular motion, with energy being transferred through the water column in a vertical direction. The forward motion of a wave is due to the energy being transmitted through the water, rather than the actual movement of individual water molecules horizontally.

When a wave passes through water, the water molecules themselves do not move horizontally with the wave. Instead, they move in a circular orbital motion as the wave passes, causing the up and down motion we see on the surface. The energy of the wave is what propagates through the water, not the actual water molecules moving in the direction of the wave.
The water does not move the raft horizontally because the force from the water is exerted in all directions equally due to its fluidity. The raft is only pushed up and down by the water's buoyant force, not horizontally. To move the raft horizontally, an external force like rowing or propulsion is needed.
Water molecules move the least in the solid state of matter, where they are tightly packed and have limited freedom of movement.
In an ocean wave, the water molecules move in a circular motion. As the wave passes through, water molecules move in an elliptical path, with no net forward movement. The energy of the wave is what is being transferred, not the water molecules themselves.
Yes, the type of wave influences how water molecules move. In deep water, molecules move in circular patterns as the wave passes through. In shallow water, the molecules move in an elliptical motion, with the bottom of the wave obstructing the circular path.
