TRAILER ADJUSTMENTS
Axle:
The amount of tongue weight on you trailer can be adjusted
as follows:
To lower the tongue weight, adjust the axle assembly
forward. To increase the tongue weight, adjust the axle
assembly backward. The distance that the axle assembly has
to be moved will vary because it is directly related to the weight
and center of gravity on the boat placed on it.
Best towing is achieved when the tongue weight is 5-7% of
the total gross load of the complete unit.
NOTE: Brake line and wire harness will need care when
moving the assembly.
Rear Support System
Place the boat on the trailer so that the transom is located at
the rear of the support system. On an RB bunk trailer, the
transom of the boat should be within 1-2” of the end of the
bunk. The center of the rear rollers on the roller rack should
be approximately 4” from the transom. This gives you
maximum support on the transom.
The rear cross member is adjustable forward or backward to
allow the trailer to be adjusted to various length boats. This is
accomplished by removing the two bolts that attach the ends
of the rear cross member to each side frame. Slide the
assembly to another set of holes provided in the side frames
that is more desirable, and then re-attach the cross member
in the new location with the bolts just removed.
The wire harness for the three-light identification light must
be re-positioned where it comes from the black wire harness
tubing to eliminate slack and sagging of the wiring.
Bunks
Make sure the bunks are positioned far enough apart to give
your boat as much stability as possible while transporting.
Position the bunks so they are located just to the outside of a
strake that your boat may have. This will help center your
boat and assist when loading. The bunks need to be adjusted
up high enough to keep the keel from resting on the center
pads. A minimum of one to two inches of clearance is
desirable.
RB Bunk trailers would be adjusted the same way.
Rollers
Position the roller racks so they are far enough apart to give
your boat stability while transporting. When the desired width
is achieved, move the roller rack system so that the rollers
are just to the outside of a strake. The rollers need to be
adjusted so that you have a minimum of one to two inches of
clearance between the keel of the boat and the center cross
member pads. This will help center the boat when loading
and unloading.
When the desired position is determined, tighten only enough
to hold the bunks or rollers from moving while the other
adjustments are being made. Final tightening will be done at
the end of the adjusting process.

Front Support System
Bunk
The front bunks should be adjusted either in or out so that
the bunk will run just to the outside of the strake of the boat.
The bunks can be adjusted either farther in or out from the
location of the rear bunk position. Adjust the bunks up so that
there is approximately 1 inch clearance between the keel of
the boat and the center cross member pad.
RB and Roller
The keel of the boat must rest on the center of the front keel
roller system creating a three-point support system. The keel
roller system is designed to fit most boats without needing
any further adjustment.
Once the boat is resting on the roller cradle assembly, the
stabilizer pads can be adjusted. This is accomplished by
sliding the pad up against the boat bottom by hand. It is not
necessary that they carry much weight. They are designed
to give your boat added stability while being towed. It may be
necessary to adjust the assembly up so that they can be
moved further apart giving additional support. Pull the
assembly away from the boat. Place the U-bolt that holds the
assembly to the cross member in a lower hole in the bracket.
Then push the assembly back against the boat. Tighten in
position.
Winch Post:
Now that all other adjustments are complete the winch post
can be adjusted. Slide the winch post base backward on the
tongue until the bow roller comes in contact with the boat.
This bow roller needs to be positioned directly above the boat
bow eye to prevent your boat from moving forward in the
event of a sudden stop. It can be moved up or down by
sliding the winch post angle tube either forward or backward
on the tongue, thus raising or lowering the bow eye roller.
Attach the winch strap and crank winch tight.
Tighten all bolts and U-bolts at this time in the winch post
assembly not previously tightened.
Attach the bow eye safety chain into the bow eye of the boat
as well. This is just another level of protection to keep your
boat and trailer together as one unit.
It may also be used to keep your boat on the trailer while
loading and unloading at the ramp, especially with a roller
trailer.
The law requires that the white ground wire on both the
tongue wire harness and vehicle harness be properly
grounded to respective trailer and vehicle frames.
See your ShoreLand’r Owner’s Guide for further technical
information regarding your trailer and its components.
NOTE: Check all fasteners, they must be
tightened before towing.
