"Set your house in order and begin for the battle to survive. Establish a strict schedule for eating, keeping watch, and getting rest. Do not drink urine or seawater. Keep busy, but avoid unnecessary exertion. The mind can be kept occupied by playing card games, Twenty Questions, or I Spy. Community singing is another surefire way to lift the spirits. Telling stories is highly recommended. Above all, don't lose hope. Few things can sap the spirit faster than seasickness. Waves are most strongly felt when a boat turns sideways to the current. A sea anchor is used as a drag to keep the boat's head to the wind. Proper use of them can increase control and reduce seasickness during rough seas."
