90% of recreational boats in the U.S. are trailerable.
Trailers present challenges and risks for boaters.
Major causes of trailering accidents:
Improper trailer maintenance
Driver error
Improper loading of the boat on the trailer
Variety of trailers available for different boat types.
Ensure the boat and trailer fit each other:
Trailer must support the total weight of the boat, motor, fuel, and gear.
Data plate on the left side of the trailer shows weight capacity and tire size.
Trailer capacity should exceed the total weight by at least 15% for safety.
Use public scales to weigh the trailer rig.
A larger trailer is easier to handle and safer.
Load must be evenly distributed to avoid stressing the hull.
Supports needed under the engine, fuel tanks, and batteries.
Consult with boat manufacturer for trailer selection.
Many boat trailers have small diameter tires that spin faster than vehicle tires.
Smaller tires often require high pressure (up to 60 PSI); low pressure can cause overheating.
Always check tire pressure when tires are cold and don’t forget the spare tire.
Wheel bearing condition is critical; use bearing protectors to keep grease in.
Overfilling grease can lead to seal failure; follow manufacturer directions.
Safety chains required for legal reasons.
Chains must be crossed under the trailer tongue and strong enough to support the fully loaded trailer.
Allow slack for turning.
Use secure forms of connections like safety links to prevent accidental disconnection.
Winches are used to load boats onto trailers; ensure they are in good condition.
No one should be in line with the cable or strap during loading.
Use strong straps for boats over 14 feet; be cautious of the ratchet on hand-cranked winches.
A wheel jack is essential for changing tires on trailers.
Tie downs are critical to prevent the boat from shifting during transit.
Secure all equipment inside the boat, including portable fuel tanks.
Most states require trailer registration and specific safety equipment.
Consult local authorities for all regulations regarding trailers.
The tow vehicle must have enough power to handle the boat and trailer.
Check the vehicle manual for maximum trailer weights and tongue weights.
Heavy-duty pickup trucks and vans are preferable for towing.
Equipment may include:
Heavy-duty engine, battery, alternator, brakes, and suspension systems.
Trailer tow packages often include necessary towing equipment.
The total trailer rig weight must not exceed the hitch load capacity.
Proper tongue weight should be about 5-7% of total weight.
Adjust balance through gear placement, axle location, or boat position on the trailer.
Perform a last-minute equipment check before departure.
Use a pre-trip checklist specific to your boat, trailer, and vehicle.
Practice towing before driving on highways; get an experienced driver to accompany you.
Distance and space requirements increase with a trailer.
Steering and driving feel different with added weight.
Practice in an empty lot to improve skills.
A helpful technique is to hold the steering wheel at the bottom and turn in the direction you want the trailer to go.
Use good weather conditions for your first highway experience with a trailer.
Maintain a greater distance from other vehicles and be cautious about passing.
Monitor sounds and handling; stop if anything seems unusual.
Be prepared at the launch ramp; check for hazards.
Avoid immersing warm bearings in cold water.
Remove tie downs, but keep the winch cable attached until ready.
Back slowly, keeping your vehicle out of the water if possible.
Guide the boat carefully while releasing the winch cable.
Be ready for the boat's movement; secure it promptly once in the water.
After use, guide the boat back onto the trailer using bow and stern lines.
Ensure cranking systems are engaged before securing the boat.
Drain the boat and secure equipment upon departure.
Sailboats are often trailered similarly to powerboats but require lowering masts horizontally.
Exercise caution when raising/lowering masts to avoid electrical wires.
Grease bulbs and sockets to prevent corrosion if wet frequently.
Inspect the trailer for rust and deterioration, especially tires.
Deterioration often occurs before tires show wear.
Store tires in a safe place when not in use.
Lock the trailer hitch and wheels, store the boat out of sight, and use unique identifying marks.
