For trailers, the steps to determining correct load
limit are:
To help guard against a sudden failure
while in use, do not use a worn hitch ball.
Replace all worn or damaged parts.
(1)
Locate the statement “The weight of cargo
should never exceed the XXX kg or XXX lbs.”
on your vehicle’s placard. See Figure S1.
(2)
(3)
This figure equals the available amount of
cargo and luggage load capacity.

TRAILER COMPONENTS
A. Bunk Supports
Determine the combined weight of luggage and
cargo being loaded on the vehicle. That weight
may not safely exceed the available cargo and
luggage load capacity.
All bunk boards are made of pressure treated wood.
This wood is rot resistant. All boards are covered with
a high quality exterior grade carpet to protect the boat
from damage during normal use.
Bunk supports run parallel to the keel and support the
hull, extending beyond the transom. See Figure S2.
Inner Bunks
Figure S1: Vehicle Placard
Improper weight distribution can place excessive
strain on the towing vehicle and trailer. It can also
cause the trailer to “fishtail” (sway side to side).
Be sure gear and other items are distributed evenly
in the boat.
Outer Bunks
Side Guides
Figure S2: Trailer Bunks
Outer bunk supports provide stability for the boat.
The inside bunks are the main weight bearing mem-
bers. Side guide-on supports (certain models only)
help to keep the boat straight while driving the boat
onto the trailer. Keeping the tie-downs tightly fas-
tened will prevent the boat from bouncing against
the bunk supports.
C. Hitches
The load-carrying capacity of trailer hitches will vary
between manufacturers and must equal or exceed
the GVWR. Four Winns® trailers use surge brake
systems and require a fixed hitch. Refer to Section
S-2E Surge Brakes for more information.
NOTICE
Improper trailer setup can cause hull damage.
Before hitching the trailer to the vehicle, make sure
the proper size hitch ball is installed to match the
coupler. The ball size is determined by the Gross
Vehicle Weight Rating or GVWR. The GVWR is
printed either on the trailer plate or embossed on
the tongue, coupler or actuator. For trailers with a
GVWR of 7000 pounds or less a 2” ball is used. For
trailers with a GVWR over 7000 pounds a 2 5/16”
ball is used. This information may also be obtained
on our website at www.fourwinns.com. Refer to
Section S-3 Operation for additional information on
hitches. Also, consult your Four Winns dealer for his
recommendation before purchasing a trailer hitch for
your towing vehicle.
B. Tongue
Four Winns trailers are designed with tongue
®
weights between 5% and 10% of the total weight
of the boat, fuel, gear and trailer. If the downward
weight on the coupling ball does not fall within this
range, coupler failure and towing instability may
occur. If using another manufacturer’s trailer, have
the dealer check the tongue weight before trailering.
