Proper Loading ‣ Never load beyond a boat’s safe carrying capacity

Reasons a Boat Rides Low In The Water and Become Unstable: • Too many people • Too much gear • Too big an engine


Freeboard ‣ The distance between the water and the gunnel or top of the sides of the boat

‣ Every boat is designed to have a certain amount of freeboard

FREEBOARD


Capacity Plate ‣ Follow the information on the capacity plate and adhere to all limits for each

‣ Required on all motorized 
 vessels less than 20 feet

Capacity Plate Information: • Maximum horsepower • Maximum number of people • Maximum weight permitted


Stay Under the Maximum Horsepower ‣ Outboard: the engine is attached to

the transom, on the stern or back of 
 the boat, and hangs over the back of 
 the boat into the water

TRANSOM

‣ The more horsepower, the bigger and heavier the

engine will be, which will cause the stern or back of the boat to be lower in the water than it should be


Stay Under the Maximum Horsepower ‣ To much weight on the transom will

cause the bow to raise up quite high

‣ Slowing the boat down will cause the

stern to become very low in the water

‣ A following ‘wake’ can easily come over the transom and ‘swamp’ the boat


Sample Capacity Exercise ‣ Older boats, and

sailboats, might not have a capacity plate

‣ A simple formula can

sometimes be used to determine the maximum number of people

Distribute The Load Evenly ‣ Distribute the load evenly fore and aft and from side to side


Keep the Load Low - Secure It ‣ Keep the load low and centered ‣ Secure it to prevent it from shifting


Passengers In Assigned Seating ‣ Make sure that all your

passengers stay seated 
 in the seats

‣ No bow riding ‣ No hanging over the gunwales


Stay Low – 
 Three Points Of Contact ‣ Stay low ‣ Move slowly

1

‣ Always have three points of contact with the boat

Boarding or Disembarking ‣ Stay low ‣ Three points of contact with boat or dock
