Common Hand signals for boaters
The water skier should be able to communicate to the towing boat with hand signals. A clear understanding in advance of the desires of the skier will lead to a safer sport. Try not to think for the skier. Let him or her direct the actions of the boat.
When a skier falls, it is important to hold up a water ski. This makes it easier for the tow boat to see you and also notifies other boats in the area that you are in the water.
Do not water ski after dark. It is very dangerous and against the law. Many states have rules regarding when you can water ski. Check for state-specific information if water skiing in an area unfamiliar to you.
