Which Boats Fit the Highliner CL21-18?
The CL21-18 is sized for boats from 16 to 18 feet long, which typically covers bowriders, centre consoles, aluminium fishing boats and runabouts. Length alone is not enough to decide, though. Check three things before you buy:
- Total weight. Add the dry weight of the hull, the engine, a full fuel tank (petrol weighs about 6 lb per US gallon), batteries and the gear you normally leave aboard. The total must stay under the 2,100 lb capacity, ideally with a margin.
- Beam. The hull must sit between the fenders. The CL21-18 has 65 inches between the fenders, so measure your boat’s widest point, including rub rails.
- Hull shape. Carpeted bunks suit most V hulls and flat bottom aluminium boats. Bunks can be adjusted to support your hull evenly.
If you are unsure, send us the boat’s make, model, length and weight and we will confirm the fit.
Carpeted Bunks
Bunk trailers support the boat along long, padded boards instead of rollers. The carpet protects the hull from scratches and spreads the load over a large area, which is gentler on fibreglass and aluminium hulls during long tows. Bunks also hold the boat steady on the road. At the ramp, wetting the carpet lets the boat slide on and off smoothly.
Why a Single Axle?
A single axle keeps the CL21-18 lighter, simpler and cheaper to run. It is easier to move by hand, turns tightly when reversing down a ramp, and has fewer tyres and bearings to maintain. For boats up to around 2,100 lb of total load, a single axle is a practical, popular choice.
No Brakes: What That Means
The CL21-18 has no trailer brakes, which keeps it light, simple and low maintenance. Unbraked trailers are common for small boats, but most countries and states set a maximum trailer weight that can be towed without brakes. Check your local rules and your tow vehicle’s unbraked towing limit before you buy, and allow extra stopping distance when towing.

Loading and Launching Tips
- Adjust the bunks so the hull sits centred and level, with the keel supported.
- Back the trailer in until the bunks are about two thirds submerged.
- Drive or winch the boat on slowly, keeping it centred between the fenders.
- Attach the winch strap and a safety chain to the bow eye.
- Secure the transom with tie down straps before leaving the ramp.
- Raise the outboard to trailering position and support it if required.
Pre Tow Checklist
- Coupler locked and safety chains crossed under the tongue.
- Jack raised and stowed.
- LED lights tested: running, brake and indicators.
- Tyres at the correct pressure for a 14 in trailer wheel.
- Wheel nuts tight and bearings greased.
- Boat secured at the bow and transom.
- Loose gear stowed inside the boat.
Maintenance
- Rinse the whole trailer with fresh water after every salt water launch, including brakes, springs and the frame.
- Grease wheel bearings regularly, and repack them once a season.
- Check tyres for cracks and wear, including the spare.
- Inspect bunk carpet and replace it when worn.
- Check lights and wiring connectors for corrosion.
- Keep the winch and strap in good condition.
