The safety of you and those on the road around you is of paramount concern.
Remember, when it's time to hit the streets, performance doesn't have
to take a back seat. Trailer towing is a special situation, which places
demands on your driving skills, and on your tow vehicle. We have included
a few basic tips that you should know in order to transport your boat
and trailer safely, comfortably and without abusing the towing vehicle.
1. Weight Distribution.
For optimum handling, the trailer must be properly loaded and balanced.
Keep the centre of gravity(CG) low for best handling.
Approximately 60% of the boat's weight should be positioned on the
front half of the trailer and 40% in the rear (within limits of tongue
weight capacity).
The boat should also be balanced from side to side. If the vessel
has side-mounted fuel or water tanks and only one side is filled, then
this will lend the rig to manoeuvre poorly. Proper balancing will also
prolong the life of your trailers tires.
The boat should be firmly secured with at lease two ratchet type straps,
attached from the trailer to the stern eyes and one ratchet type strap
from the trailer (to the rear), to the bow eye to keep the boat from
shifting forward. The bow eye should also be attached to the trailer's
winch which is mounted forward of the bow.
2. Before Starting.
Before hooking up to the trailer, make sure your tow vehicle is full
of oil and fuel. Remember, it is allot easier to fuel your tow vehicle
at a gas station without a boat and trailer attached. You should also
make sure the vehicle has plenty of water in the radiator and fluid
in the transmission. Towing a large load can often times heat up a motor
and strain a transmission. If you haven't already done so, look into
installing a transmission cooler on your tow vehicle.
Check the tow vehicle's tires for proper inflation. If you have a
dual wheeled vehicle make sure there aren't any "hidden" flats.
Connect the safety chains, and if equipped, attach the safety brake
chain.
Before starting out on a trip, practice turning, stopping and backing
up your trailer in an area away from traffic. Make sure your mirrors
give you ample vision around both sides of the boat and trailer and
if not, look into getting modified mirrors for your tow vehicle.
Check the trailer's turn signal, running and brake lights.
Check the trailer's tires and make sure the lug nuts are tightened.
A partially flat trailer tire will heat up and eventually disintegrate.
And, loosing a wheel can prove to be disastrous, especially if the loose
wheel strikes another vehicle.
Double check that the boat is secured properly to the trailer.
Check the reservoir on the trailer's surge brakes.
Check the trailer's connection to the hitch to make sure it is fastened
properly and latched. A pin, such as a cotter pin or a bolt should be
placed through the latch itself to prevent it from coming loose or being
undone by vandals while the vehicle is parked.
Check to make sure the trailer ball on your tow vehicle matches the
coupler on your trailer. The three major sizes of trailer balls are:
1-7/8", 2", and 2-5/16". Make sure the ball is fastened
properly to the tow vehicle and that the mounting will handle the capacity
equal to or grater than the weight of the trailer and boat. If you have
a receiver type hitch, make sure the insert(the bar the ball attaches
to) is secured with a retaining pin and that it has a locking clevis
pin on it.
Back slowly with someone outside the rear of the trailer to guide
you.
Place one hand at the bottom of the steering wheel and move it in
the direction you want the trailer to go.
Make small steering inputs....slight movements of the steering wheel
result in a greater movement at the rear of the trailer.
Use your mirrors. Always watch both sides of the trailer.
4. Braking.
Allow considerably more distance for stopping with a boat and trailer
attached.
If you have a manual brake controller, "lead" with the trailer
brakes first, if possible. To correct trailer side-sway, touch the manual
trailer brakes with out activating the tow vehicles brakes.
Be sure to steer as straight as possible when stopping a rig. Turning
while making a radical stop can cause the tow vehicles rear end to be
pushed forward of the front...this is called "jackknifing".
5. Downgrades and upgrades.
Downshifting assists braking on downgrades and provides added power
at the drive wheels for climbing hills.
6. Parking with a trailer.
Whenever possible, vehicles with trailers should not park on a grade.
However, if it is necessary, place wheel chocks under the trailer's
wheels as follows:
a. Apply the foot service brakes and hold.
b. Have another person place the wheel chocks under the trailer wheels
on the downgrade side.
c. Once the wheel chocks are in place, release the foot service brakes,
making sure that the chocks are holding the tow vehicle and trailer.
d. Apply the parking brake. E. Shift the transmission and make sure
it is latched there. If your tow vehicle has a manual transmission,
put the gearshift lever in reverse.
7. Acceleration and passing.
The added weight of the trailer can dramatically decrease the acceleration
of the towing vehicle. Exercise caution.
If you must pass a slower vehicle, be sure to allow extra distance.........remember,
you also have the added length of the trailer which must clear the other
vehicle before you can pull back into the lane.
Make your pass on level terrain with plenty of clearance.
If necessary, downshift for improved acceleration.
8. Driving with and automatic overdrive transmission.
With certain automatic overdrive transmissions, towing, especially
in hilly areas with heavier boats, may result in excessive shifting
between overdrive and the next lowest gear.
If this occurs, it is recommended that the overdrive gear be locked
out to eliminate the condition and provide steadier performance.
Note: See the tow vehicle's owner's manual for more information.
When there is no excessive shifting, use the overdrive gear for optimum
fuel economy.
Overdrive also may be locked out to obtain braking on downgrades.
9. Driving with cruise control.
Personally I believe that this is a no no! but if you must
When driving uphill with a large boat, significant speed drops may
occur.
A speed drop of more than 4 to 10 kms per hour will automatically
cancel the cruise control.
Temporally resume manual control through the vehicle's accelerator
pedal until the terrain levels off.
After about 100 kms, stop in a protected area and double check:
1. Trailer hitch attachment.
2. Lights and electrical connections.
3. Trailer wheel lug nuts for tightness.
4. Engine oil.....check regularly throughout the trip.
- If a flat occurs on the tow vehicle, do not use a small "donut"
type spare tire as this will drastically reduce the maneuverability
of the rig.
Hmmm might be a bit big as an example
11. Launching the boat.
Evaluate the pitch and length of the ramp as compared to the length
of the boat and trailer.
Line the boat and tow vehicle up with the ramp in a straight line.
Prepare a bow and stern line for easy retrieval and make sure any
plugs are installed prior to lauching.
Back down the ramp slowly, using someone at the back of the boat to
guide you. Make sure the wheels don't drop off the end of the ramp.
Submerge the trailer only as much as necessary to float the boat or
roll it off, depending on which type of trailer you have. Keep in mind
that if you have a multiple axle trailer, if you back one or more of
the axles over the edge of a drop off, the remaining axles will be supporting
the weight of the boat, unless, of course, the boat is supported by
its own buoyancy.
When the boat is clear of the trailer, make sure there is nothing
still attached, such as the bow strap or cable, then slowly pull the
trailer from the water.
12. Retrieving the boat.
Evaluate the pitch and length of the ramp as compared to the length
of the boat and trailer
Line the tow vehicle and trailer up with the ramp and back down the
ramp slowly
Submerge the trailer only as much as necessary to float the or roll
the boat on, depending on which type of trailer you have. Keep in mind
that if you have a multiple axle trailer, if you back one or more of
the axles over the edge of a drop off, the remaining axles will be supporting
the weight of the boat, unless, of course, the boat is supported by
its own buoyancy.
Gently drive the boat onto the trailer as recommended by the manufacturer
using the trailer's winch as directed by the type of trailer you own.
- Once the boat is straight on the trailer, double check to make sure
the bow is latched to the winch and all lines are free from the undercarriage
of the trailer.
Gently pull the trailered boat forward, making sure not to spin the
vehicles tires. Once the tires start spinning traction has been lost
and it will be almost impossible to remove the trailer from the ramp.
If the wheels start spinning, try to add more weight to the rear of
the tow vehicle. Be careful about having people climb onto the bump
of a tow vehicle as this could create an accident.
If the tires continue to spin, gently apply the parking brake while
simultaneously applying power, alittle at a time until the wheels grab
the ramp surface, and the rig moves forward.
13. Parking the trailered boat.
Once the trailered boat is ready to be parked, make sure you pick
an area which is well lit and free from falling debris, like tree leaves
and other things which can clutter up you boat.
After situating the trailered boat in the spot where you want it,
place chocks at the front and rear of all the tires.
Carefully disconnect the trailer coupling from the hitch, and unplug
all connections.
14. Long term maintenance.
After each use, the trailer's brakes should be flushed with fresh
water, regardless of whether you submerged it in fresh or salt water.
Use a petroleum based solution to wipe the tires and prevent dryrot.
Periodically grease the axle hubs, making sure not to overfill grease
retaining hubs. This could blow out the "o" ring seals and
promote premature failure.
