The cause of sea sickness although complex, can simply be described as an imbalance between the motion you witness and what is sensed by your middle ear motion-sensing organs (vestibular pathway). Prevention measures are better than relying on using medications to treat sea sickness. Situations that increase susceptibility include changes in boat motion, on-board reading, heavy weather, passenger fatigue and even extreme smells. Sea sickness can ruin sea voyages whether on small yachts or larger cruise ships.
