WARNING: There is inherent danger in using a boat -
always prepare for the unexpected. A boat which is out
of control can easily result in severe injuries or death by
drowning.
Always check weather predictions and water conditions
before a trip on the water, and also familiarize yourself with a
map of the area you’ll be traversing.
Depending on the size of your boat, make sure you bring any
proper safety equipment. Paddle(s) and a communication
device are a must for any size of boat, and if appropriate,
also bring an anchor and extra drive.
Always check your motor and system for any damage and
