Safety Cables - MasterCraft X30 Owner's Manual

To ensure that the boat is riding properly on the trailer supports, the
trailer should be in a level position when hitched to the tow vehicle.
With the trailer hooked up to the tow vehicle and the jack stowed,
measure from the bottom of the frame (behind the swing tongue) to
the ground. This measurement should be 20.5"-21.5" More impor-
tantly, failure to adjust to this height may prematurely activate the
surge brakes.
This can be corrected in a number of different ways. For example, air
pressure adjustable shock absorbers may be installed on the tow
vehicle, or you can switch from a weight-carrying to a weight-dis-
tributing hitch. Consult with the tow vehicle's dealer or manufactur-
er.
If the total weight on the loaded trailer exceeds the load capacity of
the hitch on the tow vehicle, then the trailer may break free, which
may result in serious injury or death and/or property damage.
Never Attach The Trailer To Any Device Between The
Trailer And The Tow Vehicle!
The photo shows an example of an improper device attached
between a trailer and tow vehicle that may create a dangerous con-
dition for towing a boat. Devices like the one shown in the photo may
be built or marketed with the idea of improving stability in towing,
but instead, devices of this nature may create a very unstable
condition in which control of the trailer may be lost during towing.
The MasterCraft trailer was designed and built to be attached
directly to the tow vehicle, and the trailer should only be attached
in that manner. This is especially critical in maintaining the proper
weight balance, which is described in more detail in this section of
the Owner's Manual.

Safety Cables

The safety cables on a MasterCraft trailer provide added security
so that the trailer will not become detached from the tow vehicle
when underway. These cables conform to the Society of Automotive
Engineers (SAE) J684 standard for trailer coupling and hitches au-
tomotive type. If it ever becomes necessary to replace these cables,
ensure that the replacement cables meet this standard.
Failure to properly attach the safety cables and brake actuator
break-away cable between the trailer and the tow vehicle may
result in a runaway trailer if the trailer coupler becomes detached
from the hitch. This may cause serious injury or death and/or
property damage.
The strength rating of EACH safety cable must be equal to or ex-
ceed the trailer's GVWR (Gross Vehicle Weight Rating).
