Category Three: Boats Rated for Manual
Propulsion and Boats Rated for Outboard Motors of 2 Horsepower
or Less
Persons Capacity: Maximum weight capacity:
Boats rated for manual propulsion and boats rated for motors
of two horsepower or less. (Category Three)
Discussion:
As in the other categories, persons capacity is calculated
and stated in the capacity label in two forms; expressed in
pounds whole numbers. These calculations are straightforward
and easy to complete.
The static float plane and the maximum displacement
have been calculated in section 7.1 to get the maximum weight
capacity, so following the regulation is easy, and there are
two options:
- If the boat is strictly for manual propulsion,
the persons capacity in pounds is 90% of its maximum weight
capacity
- If the boat is rated for 2 horsepower or
less, the persons capacity in pounds is 90% of its maximum
weight capacity minus 25 pounds (allowance for the engine)
Either one of these figures expressed as “pounds
of persons” is the certified persons capacity figure
to be displayed in the capacity label.
As mentioned above, the maximum persons capacity
also must be expressed in a whole number of persons. Its calculation
is straightforward and follows the two options above.
1) If the boat is strictly for manual propulsion,
follow this formula
| Person Capacity (no.) = |
32 + persons capacity (lb.) |
| |
141 |
2) If the boat is rated for 2 horsepower
or less, the formula is
| Person capacity (no.) = |
32 + [persons capacity (lb.) –
25] |
| |
141 |
Either one of the figures for persons capacity
in whole numbers must be rounded in the usual manner; if the
fraction is less than half, to the next lower number. If it
is half or greater, it may be rounded to the next higher number.
As in the other categories, the manufacturer is allowed to
de-rate the capacity to be stated in the capacity label.
