For trailers, the steps to determining correct load limit
are:
dealer for his recommendation 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.
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.

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
Outerbunksupportsprovidestabilityfortheboat. Thein-
side bunks are the main weight bearing members. 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.
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
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.
7000
pounds a 2 5/16” ball is used. This information
