How not to get sick at sea

Typical indicators of sea sickness are a dry mouth, cold sweat, dizziness and nausea, sometimes followed by vomiting.

Medically speaking, sea sickness is a variation of motion sickness or kinetosis. Although it does not always end up with the affected person "feeding the fishes", it can ruin a boat trip but, with the right medicine and a few useful tips, it can be kept under control.

Kinetosis is caused when "the body experiences difficulty with different and contradictory stimuli", according to Michael Knappich, a doctor at the Berlin Center for Travel and Tropical Medicine.
