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.
- 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.
- 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.
10. On the Road.
- 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.
