Launching Tips and Techniques
Every MasterCraft boat owner develops his or her own favorite
launching technique.
Check the ramp first
Whether launching from an unimproved or surfaced ramp, check it out
before starting the launch procedure. How steep is it? Is the surface
firm enough to support the weight of the trailer and tow vehicle? Is it
wide enough? How deep is the water at the end of the ramp?
Use great care when walking, standing or loading and unloading
boats on or around any launch ramps because some launch ramps
may be slippery when wet.
Prepare for launching
Install the drain plugs and detach the trailer tie-downs.
Slowly back the trailer down the ramp
If possible, have someone stand to one side of the ramp to provide
directions. Backing up a trailer can be tricky. A good way to simplify the
procedure is to grasp the steering wheel with one hand at its lowest
point (6 o’clock). To make the trailer go right, move your hand on the
wheel to the right (move the wheel counter-clockwise); to make the
trailer go left, move your hand to the left (move the wheel clockwise).
Signal your intentions
Well before stopping, turning, changing lanes or passing, use turn
signals to let other vehicles know what you intend to do.
Drive in tow vehicle manufacturer recommended gear
If the tow vehicle has a manual transmission, traveling in lower
gears when going up steep hills or over sand, gravel or dirt roads
will ease the load on the engine and transmission. When driving on
long downhill grades, try to avoid down-shifting. Running in a low
gear going downhill, which uses the engine as a brake, can actuate
the trailer’s surge brakes continuously for the duration of the grade,
causing them to over-heat. A better procedure is to slow down be-
fore the start of the down grade and maintain a controlled downhill
speed with repeated application and release of tow vehicle (and
thus, the trailer) brakes. This technique permits the brakes to cool
down between applications and provides for reserve braking capac-
ity in an emergency. On moderate and steep sections, down-shifting
into lower gears may be unavoidable. Slowing down is important
to allow the brakes to avoid overheating. Don’t hesitate to pull over
when possible during or after severe braking situations and allow
the system to cool down. Running a stretch of highway where
braking is not necessary is the quickest way to cool down the brake
system because it allows a significant volume of air to flow through
the vented rotors and over the brake pads.
Slowly back the trailer into the water until the transom floats four
(4) plus inches off of the trailer. The depth of the trailer to achieve
this will vary depending on ramp angle. Set the parking brake and
shift into park (automatic transmission) or first gear (manual trans-
mission). Shut off the engine. Unlock the Ramp-N-Clamp (where
equipped) latch and winch hook; then back the boat off the trailer.
Reloading the trailer
To reload the boat on the trailer, simply reverse the above proce-
dures, including setting your Ramp-N-Clamp to the proper position,
and drive the boat onto the trailer at a slow pace. Before loading,
clean any dirt or sand off the rollers and bunks. Sand on these can
abrade the boat’s bottom while on the road. Be sure to back in and
completely wet the trailer bunks, then pull forward to the loading
position.
Be certain all the boat tie-downs are properly fastened down before
departing from the launching ramp area. Proper loading depth on
trailers will vary with conditions, but a good starting point would be
the same as launch depth or slightly higher.
NOTE: After the launch depth has been properly determined, apply
a strip of reflective tape at the water level on each guide post. That
will allow launch depth to be easily repeatable.
For the X10 XT23, X46, NXT20 and ProStar trailers, it is important
to back the trailer deeply enough into the water to load the boats
so that the hull does not impact the back edge of the center bunk
boards during loading. If the boat is loaded in too shallow conditions,
Always be courteous
Make it as easy as possible for faster-moving vehicles to pass you.
Remain in the slower lane and be prepared to reduce speed if they
need extra time to return to the lane.
Do not tailgate
Allow at least one combined car and trailer length between you and
the car ahead for every 10 mph you are traveling.
If a problem occurs, stay calm
Do not panic and do not do anything anymore suddenly or violently
than is necessary.
Sudden bumping or fish-tailing may be a flat tire
Do not jam on the brakes or mash the accelerator to try to drive
out of it. Stop slowly and in as straight a line as possible. If condi-
tions permit, allow the trailer and tow vehicle to coast at a very slow
speed and try to avoid braking, except when the wheels are straight
ahead and the trailer and tow vehicle are in line.
If the trailer begins to fish-tail under acceleration to highway speed,
back off the accelerator a little, and it should cease. If it begins again
upon acceleration, stop and check the load. If the load is not evenly
distributed, or if it is too far back so that the hitch load becomes
too light, the result can be fish-tailing. Redistribute the load before
continuing.
