B. Skiing • Anyone who water skis must know how to swim. • Never drive the boat directly behind a water skier. At 22 knots (25 m.p.h.), it takes only 5 seconds to overtake a fallen skier who was 60 meters (200 feet) in front. • Keep a downed skier in sight and on the operator's side of the boat when approaching the skier. Never back up to anyone in the water. • Learn the signals to communicate with a skier. The skier is to control the boat through hand signals. (See Figure 1.10.1) ! WARNING Hitting an object in or under the water or boating in dangerous currents can cause serious injury or death to boat occupants. You must know where the hazards are and avoid them. In uncharted waters, boat very slowly and post a lookout. ! WARNING Shut engine off if an object is struck or if you run aground. Check for hull leaks and propulsion system damage, before restarting engine. Use hand pump if bilge pumps don't remove water. Boat very slowly, if you must proceed with a damaged propulsion system. ! WARNING Skiers must wear an approved PFD. DANGER ! Your boat's propeller can kill or injure persons in the water. Always stay away from areas designated for swimming or diving. Unless you are towing a skier, stay away from water ski areas. Recognize markers used for such areas. When engine is running, close and lock transom door and do not permit anyone to use boarding ladder and swim platform. ! WARNING If the skier suddenly releases the tow rope, it can backlash into the cockpit. Spotters who are watching the skier must be made aware of this fact and be prepared to deflect the rope by hand to avoid injury. Turn - Arm raised, circle with index finger extended. Skier in Water - Extend one ski vertically out of water. Back to Dock - Pat top of head. Cut Motor - Draw finger across throat. Slow Down - Thumb pointed down or palm down, move hand up and down. Faster - Thumb pointed up or palm up, move hand up and down. Speed OK - Raise arm and form a circle with thumb and index finger. Stop - Raise arm with palm vertical and facing forward. Turn Right - Extend right arm out from body to the right. Turn Left - Extend left arm out from body to the left. OK After a Fall - Clasp hands together overhead. C. Diving Recognize and respect diving flags. (See Figure 1.10.2) Keep at least 30 meters (100 feet) away. Sport Divers Flag – Red flag with diagonal white stripe marks a diver in the water. Code Alpha Flag – Blue and white pennant designates boat being used in dive operations In General When engaged in water sports, be safe and courteous to others sharing the water: • Be considerate to fishermen. • Do not water ski in congested areas. • Keep the boat and skier away from navigation markers. • Stay well clear of other boats and skiers. 16. Emergency Situations Prevention is the safest approach. We hope that you are never involved in an emergency situation. If you are involved in an emergency situation, it is imperative that you know how to react, in order to protect the lives in your care. SKIING SIGNALS (FIG. 1.10.1) DIVERS FLAGS (FIG. 1.10.2) WHITE RED BLUE WHITE SPORT DIVER'S FLAG CODE ALPHA FLAG notice ASSISTING OTHER BOATERS: All boaters have an obligation to help other boaters who are in distress, as long as rendering assistance does not endanger you, your passengers, or your boat. A. Medical Emergency You may be far from professional medical help when you are boating. At least two people on board your boat should be CPR certified, and should have taken a first aid course. Equip your boat with a first aid kit. B. Water Rescue A person who has fallen overboard will die from hypothermia in water temperatures below 70°F if not rescued quickly. Water rescue consist of three steps: returning to the victim, making contact with the victim, and getting the victim back on board. Returning to the Victim • Immediately make everyone aware of the incident and keep the victim in sight. • Slow the boat and keep pointing toward the person overboard. At night, direct the best available light source at the person. • Throw a life preserver, even if the person is wearing a PFD. It will serve as another marker. Making Contact • Slow the boat and circle toward the victim. • Try to approach heading into the wind or into the waves. • Keep the victim on the right (starboard) side so the boat operator has the victim constantly in sight. • When almost alongside, turn off the engine in gear to prevent propeller "windmilling." Getting Back Aboard • Try to reach the victim with a pole, or by throwing a life preserver. Do not swim to rescue the victim, except as a last resort. • Assist the person in boarding the boat. The person should normally be brought in over the stern. • If the person is injured or cannot get into the boat, a rescuer should put on a PFD with a safety line attached to the boat and enter the water to assist the victim. • Handle the victim with care. Spinal injuries may have occurred. C. Fire Fire is a serious boating hazard. Boats can burn...
