Basic paddle and arm signals for sea kayakers

There are many different ways to communicate with your paddling partners while you are paddling in open sea. One of the more reliable ways of doing so is with paddle or arm signals. Your paddle or arms can be seen over farther distance than hand signals and noise cannot drown them out.

Keep in mind not everyone speaks the same paddle language so it is important to review signals within your group at the beginning of the day and agree upon their meaning. The signals mentioned below and how to use them with your paddling partners should be discussed and agreed upon before you get on the water.

The signals are primarily for directing the movements of kayakers. Below are the basic signals performed with paddles and their corresponding arm signals. When doing paddle or arm signals, be sure the flat of the blade or hand is used whenever possible for greater visibility

A vertical paddle or arm means GO. On a tour the go means paddle in the agreed upon direction previously discussed.

The paddle held horizontal or the arms out stretched to the side means STOP your paddling and/or hold your position. The stop means keep the kayak where it is. If there is a current you may have to be paddling to hold the position    

If you alternately move each end of the paddle up and down or each arm, it means move BACKWARDS in your kayak. This is most often used to back away from obstacles.

To move the kayaker to the right or left, point your paddle or one arm, up and to the side you wish them to travel.

In many sports the waving of your hand from side to side means EMERGENCY. Using the paddle is also effective. Many kayakers use the side to side wave as emergency if it is done quickly and a GATHER-UP signal, if it is a slow wide wave to the group.

If I want to signal that I am OK or ask if someone is OK, I will hold one arm out to the side and then place my fingertips back over my head. I am attempting to make the letter "O" on one side of my body with my arm.
The OK sign can be a question or a response depending on the situation. When I see someone take a bad spill in the surf but they flash me the OK sign I appreciate the proactive message. I respond with the OK sign as a confirmation.
If I ask a fellow paddler if they are OK and I get no response, I keep trying. If still no response I assume they need help. This is also assuming I know that they understand the OK signal.

Note:
As mentioned earlier, these signals have some common threads crossing over to whitewater paddling, rafting and SCUBA diving but don't assume they are universal. It would be nice if some basic ones were adopted by all. The emergency and OK symbol is more widely accepted. The others are gaining more popularity.
