Carbon Monoxide (CO) can affect passengers in boats, whether they are at speed, anchored or idling. CO levels from boat exhaust can reach critical levels in a short time.

  • You cannot see, smell, or taste CO
  • Keep away from engine and generator exhaust outlets.
  • Never sit, teak surf, or hang on the back deck or swim platform while the engines are running.
  • Never enter areas under swim platform where exhaust outlets are located.
  • Install and maintain CO alarms inside your boat. Do not ignore any alarm.

Symptoms of CO poisoning include:

  • Severe headache, dizziness, confusion, nausea, fainting.
  • When the concentrations of CO is high, unconsciousness can be the first sign of CO poisoning and this can occur without any of those symptoms
  • If you suspect CO poisoning, immediately get the victim to fresh air and seek medical care.

Sources of CO poisoning:

  • Inadequately ventilated canvas enclosures.
  • Exhaust gas trapped in enclosed places.
  • Blocked exhaust outlets.
  • Another vessel’s exhaust.



Dehydration is often the underlying cause of sickness and accidents on the lake.

  • Drink eight to 10 eight-ounce glasses of water daily or more during extreme heat, low humidity or activity.
  • Avoid caffeinated or alcoholic beverages.
  • Protect your skin: wear sunscreen, protective clothing, and reduce activity during the hottest part of the day (10 a.m. to 3 p.m.).
  • Check the color your urine. It should be a pale yellow, like the color of straw. If it is dark, drink more fluids.

If you become dehydrated:

  • Stop activity, rest and get out of direct sunlight. Drink 64 oz of cool liquids (including rehydration fluids) over the next two to four hours.
  • Seek medical attention if...
    Dizziness, weakness, confusion, fainting, fast-beating heart or no urination for eight hours.



Impacts from wakes can cause a boat passenger to be thrown into the air and land forcefully back onto the boat.

If you have been injured by a wake:

  • Lie down on your back on a very firm, flat surface, and keep still until medics can reach you, or you can obtain medical attention.
  • If you have any numbness, weakness, loss of control of urine or stool, radio for help immediately.


  • Slow down when passing boats.
  • Approach large boat wakes at a 45-degree angle.
  • Warn all passengers to hold on when approaching a large wake.
  • Bow riding (sitting on the top front part of the boat) is illegal unless the boat is designed for people to ride in the bow section (the bow section will have seats).
  • Look at the size of the wake, not the size of the boat. Depending on hull design, even relatively smaller boats can produce serious wakes.
  • Be aware of wakes and waves that bounce back and forth between canyon walls.
