Waves will move on forever, probably higher then they are on Earth oceans. The atmosphere will have a higher humidity coefficient. In such an environment, hurricanes will continuously form close to the equator and slowly migrate to the poles. In some places, water will be over 20 km deep. Mount Everest will be 1152 meters below sea level.
This is how Earth would look like if the oceans were 10 km higher then they are today. The main difference is that this planet, similar to Earth, has no piece of dry land. Imagine a planet orbiting at the Comfort Zone, the best orbit in the Habitable Zone of a star. Depending on what their parent star is, on their orbit and distance and on Geographic features, these worlds can be or not a good destination for future settlers. Terraforming processes can transform an ice-covered world into an oceanworld. Many scientists have theorized ocean planets to exist around stars. Many celestial bodies can contain too high an amount of water.
