6. Perform the first measurement with the swim platform loaded and the person measuring the

7. Load the swim platform if equipped.
8. Measure the exhaust elbow waterline height.
IMPORTANT: View all boat seating as rows that are parallel to the transom of the boat.
9. Load a person weight into a seat, and measure the exhaust elbow waterline height after each
person weight is loaded onto the boat. Repeat until a person weight is is loaded into each seat
in that row.
10. Continue the process moving forward toward the bow of the boat to the next row of seats until
a person weight is loaded into each seat.

EXAMPLE

NOTE: The following example is provided as a reference.
This example uses a boat that is 8.84 m (29 ft.) long and greater than 8.84 m (29 ft.) long, that
does not have a maximum rated swim platform weight capacity, and must add 226.80 Kg
(500 lb.) to the swim platform .
IMPORTANT: The Designated Seating Diagram following illustrates the number of passengers
that can sit on designated seating excluding cabin space.
This example uses 9 persons as the maximum passenger load.
NOTE: Use 0.50 lb. as the break point to round up or down to obtain a whole pound.
1. To determine the maximum cargo load multiply the maximum passenger load by the maximum
cargo weight per passenger.
2. To determine the preferred cargo distribution for aft, center, and bow storage:
a.
3. To determine the maximum center storage cargo weight, multiply the maximum cargo weight
by 50%
a.
b.
4. To determine the maximum bow storage cargo weight, multiply the maximum cargo weight
by 25%

Designated Seating Diagram
9 passengers × 25 lb. = 225 lb.
To determine the maximum aft storage cargo weight, multiply the maximum cargo weight
by 25%
225 lb. × 50% = 112.50 lb.
112.50 lb. rounded up = 113 lb.
