35.6
DETERMINATION OF LOAD CAPACITIES
35.6.1
Maximum Weight Capacity
35.6.1.1 Two Tube Pontoon Boats: The maximum weight
capacity of a two tube pontoon boat shall be determined by
obtaining the pontoons' submerged displacement in pounds,
subtracting the boat weight, and dividing by the sum of the
following: the square root of the tube diameter in inches,
minus 2.35, or
Designated occupant position - a position designed for
occupancy while the vessel is underway at any speed.
Seated positions shall have a minimum width of 16 inches
measured at the midpoint of the depth of the seat.
Horsepower (hp) - The manufacturers advertised or
specified power output for a given engine.
35.6.1.1.1 determined by actual weights required to cause
the pontoons to be awash over their entire length. Add this
weight to block V. of the Pontoon Capacity Worksheet (see
Maximum weight capacity - The maximum load in pounds
that a boat may carry. This load includes persons, portable
fuel tanks, and all gear not part of the boat’s structure, and,
if recommended for use with outboard engines, includes
outboard engines, throttle and shift controls, and batteries.

35.6.2.3.2 The transverse stability test shall be conducted
on each side of the boat, or on the heavier side of the boat.
Conduct this test by adding weight evenly distributed fore
and aft on the deck as far outboard as practicable, i.e.,
within one foot of the edge, until the top of the pontoon on
the loaded side becomes awash.
35.6.1.2 Three Tube Pontoon Boats: The maximum
weight capacity of three tube pontoon boats shall be
determined by obtaining the pontoons' submerged
displacement in pounds, subtracting the boat weight, and
dividing by the sum of the following: the square root of the
tube diameter in inches, minus 1.35, or
35.6.2.3.3 The longitudinal stability shall be tested by
adding weight on the deck with the weight’s center of
gravity on centerline, and 1/4 of the length of the deck
from forward, until the forward edge of the deck becomes
immersed. This test shall be repeated by adding weight on
the deck with the weight’s center of gravity on centerline,
and 1/4 of the length of the deck from aft, until the edge of
the deck, or the top of the engine mounting bracket,
becomes immersed, whichever occurs first.
35.6.1.2.1 determined by actual weights required to cause
the pontoons to be awash over their entire length. Add this
weight to block V. of the Pontoon Capacity Worksheet.
(See
Figure 1 or FIGURE 2).
NOTE:
Figure 1 and FIGURE 2 provide a calculation method for
determining weight capacity for outboard, inboard and
sterndrive, and manually propelled pontoon boats.
35.6.2.3.4 In a design having more than one deck level
intended for passengers, i.e. having railings and a means of
access, the test in .2 and .3 above shall also be conducted
by adding weight on the upper deck equal to the maximum
capacity specified by the manufacturer for that location at
one side against the railings. A weight equal to the total
capacity, minus the upper deck weight, shall be placed on
the same side of the lower deck as the weight on the upper
deck. This weight shall be placed against the railings and
distributed equally along the side of the lower deck fore
and aft. If the pontoon boat exceeds the limits of immersion
specified in .2 or .3 above, either the total persons capacity,
or the upper deck persons capacity, shall be reduced to
meet these conditions.
35.6.2
Persons Capacity
35.6.2.1 Pontoon boats with more than one deck level or
with a deck width within railings defining the passenger
carrying area that overhangs the pontoon shall use the
method for determining persons capacity described in
H-35.6.2.3.
35.6.2.2 The persons capacity in pounds of pontoon boats
shall be determined by either H-35.6.2.2.1 or H-35.6.2.2.2,
and shall not exceed the number of designated occupant
positions intended to be occupied when the boat is
underway at speeds greater than five mph.
35.6.2.2.1 For outboard powered pontoon boats, the
persons capacity in pounds is equal to the maximum weight
capacity minus the weight from ABYC S-30, Outboard
Engine & Related Equipment Weights,Table 1, Column 10.
35.6.2.3.5 Ninety percent (90%) of the lesser of the
weights attained in steps .2, .3, or .4 above shall be the
maximum persons capacity.
35.7
DETERMINATION OF HORSEPOWER
CAPACITY
35.6.2.2.2 For inboard/sterndrive powered pontoon boats,
the persons capacity in pounds is equal to the maximum
weight minus the following: the heaviest applicable
published engine, drive, control, battery and propeller
weights.
35.7.1
Determine the maximum horsepower for pontoon
boats recommended for use with outboard engines as
follows: HP = volume of pontoons (ft.
3
) x the longest
pontoon length (ft) ÷ pontoon diameter (inches)
35.6.2.2.3 The maximum number of persons is
determined by the maximum pounds of persons divided by
141, and rounding off the result to the nearest whole
number. If the fraction is less than one-half, round down to
the next whole integer. If the fraction is equal to, or greater
than one-half, round up to the next higher whole integer.
(See
NOTES:
1. If pontoons are not circular in cross section, take
the cross section area of the pontoon and calculate a
circle of the same area. Where tubes vary in geometric
shape, add the calculated diameters together and divide
by the number of tubes.
Figure 1 and FIGURE 2.)
2. You may round up to the next 5 h.p. increment.
35.6.2.3 Pontoon Boat Persons Capacity Test Procedure
35.7.2
If twin engines are used, their total horsepower
shall not exceed the horsepower capacity determined in
H-35.7.1.

35.8.1.1 pontoon boats that are capable of a top speed of
30 miles per hour (26 knots) or more, using the
manufacturer's rated horsepower.
35.8.2
The maneuvering speed shall be determined by
the quick turn test. (See H-35.9.)
35.8.3
If a maneuvering speed less than the top speed of
the pontoon boat is determined, it shall be posted on the
boat, in a location clearly visible and legible to the
operator, and contain the following informational elements:
35.8.3.1 the hazard level intensity signal word;
35.8.3.2 nature of the hazard;
35.8.3.3 the consequences that can result if the
instructions to avoid the hazard are not followed; and
35.8.3.4 instructions on how to avoid the hazard.
Note: An example of such a label follows.
WARNING

speed obtained with the boat prepared as described in
H-35.9.1.
35.8.5
A speedometer shall be provided on pontoon
boats when the maneuvering speed is less than the top
speed of the pontoon boat.
35.9
MANEUVERING SPEED TEST
PROCEDURES
35.9.1
Boat Preparation
35.9.1.1 The pontoon boat shall be rigged with equipment
recommended or provided by the boat manufacturer, and
tested with the highest horsepower production
powerplant(s) for which the boat is to be rated, i.e,
outboard engine(s), or which is to be installed in the boat,
i.e., sterndrive(s) and inboard(s). Equipment shall be
installed in accordance with manufacturer's instructions.
35.9.1.2 Install a speedometer. (See H-35.9.2.4.)
35.9.1.3 Install the lowest ratio, i.e., quickest steering
system offered on the pontoon boat model being tested.
35.9.1.4 Mount the engine manufacturer's recommended
propeller providing maximum speed.
35.9.1.5 Standard permanently installed fuel tanks shall
be no more than one-half full. Pontoon boats with outboard
engines, and without permanently installed fuel tanks shall
be tested beginning with one full portable tank for each
engine. Portable tanks shall be in their designated location,
or placed as far aft as practicable.
35.9.1.6 Place the outboard engine in the lowest vertical
position on the transom, or, if mounting instructions are
provided, at the height recommended. If a mounting height
above the transom is recommended and tested, then the
highest horsepower for which flush transom mounting is
recommended shall be tested.
35.9.1.7 Boat bottom, engine, and propeller shall be clean
and in like new condition.
35.9.1.8 The use of the following special equipment shall
be considered because of the potential for exceeding the
capabilities of the pontoon boat while performing this test;
35.9.1.8.1
racing type PFD,
35.9.1.8.2
helmet, and
35.9.1.8.3
emergency ignition stop switch.
35.9.2
Test Conditions
35.9.2.1 Testing shall be conducted on calm water with
the wind speed below 10 mph (9 knots).
35.9.2.2 The test shall be conducted with no load other
than a driver who shall weigh no more than 200 lbs.
35.9.2.3 The engine trim angle shall be adjusted to
provide maximum full throttle speed short of excessive
porpoising or propeller ventilation so that there is no loss
of directional control.
35.9.2.4 The maximum full throttle speed and the
maneuvering speed shall be verified by radar, GPS, or
other electronic means, or by the average of not less than
two timed passages over a measured course in both
directions.
35.9.3

Page 5
H-35
7/03
35.9.3.1 Set throttle at a comfortable maneuvering speed
(low) and conduct the quick turn test.
35.9.3.2 To conduct a quick turn test, the driver operates
the pontoon boat straight ahead at a given throttle setting.
The wheel is turned 180° in the direction of least resistance
in 1/2 second or less and held at that position without
changing the throttle or trim settings during or after the
wheel change. The pontoon boat completes the maneuver
successfully if it is capable of completing a 90° turn
without the driver's loss of confidence in maintaining
control of the boat.
35.9.3.3 If the pontoon boat successfully completes the
quick turn test, increase the boat's turn entry speed
incrementally until the boat does not complete the test or
successfully completes it at maximum throttle.
35.9.3.4 The highest speed at which the pontoon boat
successfully completes the quick turn test is the
maneuvering speed.
