Use flotation devices. Have an approved personal flotation device of suitable
size for each person aboard (it is the law) and have it readily accessible.
Do not overload your boat. Most boats are rated and certified for maximum
load (weight) capacities (refer to your boat capacity plate). If in doubt, contact your dealer or the boats manufacturer.
Perform safety checks and required maintenance. Follow a regular schedule
and ensure that all repairs are properly made. Know and obey all nautical
rules and laws of the waterways.
Make sure everyone in the boat is properly seated. Do not allow anyone to
sit or ride on any part of the boat that was not intended for such use.
This includes the back of seats, gunwales, transom, bow, decks, raised fishing seats, any rotating fishing seat; or anywhere that an unexpected acceleration, sudden stopping, unexpected loss of boat control, or sudden boat
movement could cause a person to be thrown overboard or into the boat.
Never be under the influence of alcohol or drugs while boating (it is the law).
Alcohol or drug use impairs your judgment and greatly reduces your ability
to react quickly. Prepare other boat operators. Instruct at least one other person on board in the basics of starting and operating the outboard, and boat
handling, in case the driver becomes disabled or falls overboard.
Passenger boarding. Stop the engine whenever passengers are boarding,
unloading, or are near the back (stern) of the boat. Just shifting the outboard
into neutral is not sufficient.
Be alert. The operator of the boat is responsible by law to maintain a proper
lookout by sight and hearing. The operator must have an unobstructed view
particularly the front. No passengers load, or fishing seats should block the
operators view when operating the boat above idle speed.
Never drive your boat directly behind a water skier in case the skier falls. .
Watch fallen skiers. When using your boat for water skiing or similar activities, always keep fallen or down skier on the operator’s side of the boat while
returning to assist the skier. The operator should always have the down skier
sight and never back up to the skier or anyone in the water.
