Loading the Boat with a Capacity Plate

For boats with a capacity plate, use the maximum load for persons and gear as listed on the
capacity plate to determine the number of persons to place onto the boat for exhaust elbow
waterline height measurements.
IMPORTANT: Use 20 inches for average passenger seat width when measuring bench seating.
Round up or down at 0.5 to obtain a whole person. See the examples listed below.
• 48 in. (bench seat length) ÷ 20 in. (seat width) = 2.4 persons. 2.4 persons rounded down = 2
persons.
• 55 in. (bench seat length) ÷ 20 in. (seat width) = 2.75 persons. 2.75 persons rounded up = 3
persons.
1. Take the maximum capacity weight as listed on the capacity plate (XXXX lb. Persons, Gear)
and subtract the swim platform load, if applicable.
2. Next divide the weight by 74.84 kg (165 lb.) per person. This gives the whole number and
remainder of 74.84 kg (165 lb.) persons to load onto the boat.
3. Put the remainder of a person in the next available seat. See Boat loading diagram.
CE Capacity Plate
IMPORTANT: If there is not enough seating for the number of people, treat the leftover weight as
cargo. Load cargo weight onto the boat before loading passenger weight.
4. If applicable, load cargo (leftover persons weight) onto the boat. Distribute cargo as described
below.
IMPORTANT: If the boat configuration does not allow for aft, center, and bow storage, choose the
storage application from the Optional Cargo Distribution table that best applies to your boat
configuration.
5. Perform the first measurement with the swim platform loaded and the person taking the
waterline measurement on the boat.
