All watercraft are exposed to all types of waves because the waves always crash against the sides of the boat and can cause the vessel to capsize. Many people get seasick even from slight rocking on board. This effect can be significantly reduced with a raft, where a platform is installed high above the raft, above the waves. The tubes, which are deep in the water, are washed over by waves without hitting the sides of the boat, because there are no sides. The waves always splash under the platform without touching it. This makes it possible to build floating houses on the water
