For trailers, the steps to determining correct load
limit are:
before purchasing a trailer hitch for your towing
vehicle.
(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.
To help guard against a sudden failure while
in use, do not use a worn hitch ball. Replace
all worn or damaged parts.
(2) This figure equals the available amount of cargo
and luggage load capacity.
(3)
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.
S - 2 TRAILER COMPONENTS
A. Bunk Supports
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.
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.
C. Hitches
Figure S2: Trailer Bunks
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.
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 fastened
will prevent the boat from bouncing against the bunk
supports.
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.

tion for additional information on hitches. Also, consult
your Four Winns dealer for his recommendation
