Keep dry clothes in a dry storage container in the boat. Falling in or flooding waders will lead to hypothermia quickly. Hypothermia can set in before returning to the launch site and having dry clothes to change into will slow that process considerably.
Pay attention. Paying attention to detail when motoring open water will help avoid debris; logs, stick ups, sand bars, and even trash that could damage motors and boat hulls.
Never get complacent. Complacency can lead to trouble and on many big rivers and lakes a simple mishap can leave you stranded or worse. Respect the dangers of your surroundings.
Avoid boating unfamiliar areas. Maps and thorough scouting of areas will help you avoid many dangers. Visiting hunting spots in the daylight will allow you to acknowledge stumps and sandbars before hitting one in the early morning hours.
Have a plan. Planning accordingly for different situations that can arise during a day waterfowl hunting will help you be better prepared when something goes wrong.
