How to use a trailer winch with webbing
Updated: 22 October 2026
You have bolted, or are about to bolt, a strap hand winch to a trailer post, and the first real pull is where theory ends. UK reviews on the KATSU listing already describe a jamming bar that snapped, a handle that can spin, and a boat that was no longer held when the mechanism failed. The [belt winch comparison](/hub/lifting-equipment/belt-winch) ranks the three listings. This page is how to use a trailer winch: the sequence and the stop points. Peter F. checked the amazon.co.uk notes on 20 October 2026. There was no load test. A qualifying purchase can earn a commission at no extra cost to you.

Before the first crank
Start with a mount that can take the pull in line with the strap, not twisted sideways on rusty plate. KATSU buyers report that nuts and bolts are not in the box, so plan fixings before launch day. The FreeTec listing does not state what is included. Assume you must supply grade-appropriate bolts, washers and a backing plate if the trailer manufacturer calls for one. Do not guess a bolt size from a US Fulton manual for a different winch. Use the trailer maker's guidance or measure the existing holes.
Lay the strap flat on the drum before load. A folded strap can jam between wraps and load the edges of the webbing instead of the full width. Hook or buckle to a rated point on the boat or load, keep bystanders out of the line of the strap, and walk the hull if you can so the winch is not fighting a sideways drag.
Read the pulling-only line on FreeTec if that is your unit, and keep suspended lifts off this hardware. The split between supported pulls and lifts lives on how to choose a strap winch. Here the rule is simpler: if the load would hang, stop.
Cranking under load
Engage the ratchet pawl before you trust the handle. Manufacturer guidance for trailer winches in general, not a quote from these three instruction sheets, which the listings do not supply, says keep hold of the handle until the pawl is seated. On KATSU, a UK review warns that selecting freewheel while the strap is loaded lets the handle spin and the gears run free. That is an injury path, not a convenience feature under tension.
Crank steadily with the strap in the line of pull. If the teeth skip, the strap folds, or you hear grinding from deformed ratchet teeth like those described on KATSU, stop and unwind under control if you can. Do not add people on the handle to force it free. FreeTec's bullets name two-way pawls. Treat that as a reason to confirm direction before each session, not as proof the unit is maintained.
Stay out of the strap's path. Fibre and wire both store energy, and a break can whip. HSE material on lifting equipment reminds you not to use damaged line. Here that means retire a cut strap or bent frame before the next launch.
Paying the strap out
Freewheel or free payout is for unloaded strap only. Select it when the hook is slack and you are spooling out for adjustment, not when the boat is dragging on the ramp. If you must pay out under light tension, keep a hand on the handle until you are sure the pawl will hold when you reverse direction.
When the strap is fully slack, check wraps remain on the drum. Do not run the drum empty under load.
After the load is home
The winch recovers the hull the last few metres onto the trailer. It is not the motorway restraint. Axforth's boat-trailer guidance describes winching onto the trailer, then an independent bow restraint and stern straps before you drive. A ratchet alone can release if the pawl slips or someone selects the wrong mode.
The slipway-to-road handoff is on belt winch on a boat trailer. If grease on the gears helped a FreeTec owner but plating doubt remains after salt water, treat maintenance as part of use: rinse, dry and inspect before you rely on the pawl again.
When to stop
Stop using the winch when ratchet teeth look bent, the jamming bar is cracked, the handle spins under load, or a failure of that kind has already happened to you once. Retire the unit. Do not see if it holds on the next trip.
Stop the purchase when the listing never settled strap versus rope, when you needed pulling-only language and the page is silent, or when your load exceeds the lowest figure you trust. That decision belongs on the buying guide and the main comparison, not at the slipway.
Common questions
What do I bolt it to if the box has no bolts?
Use trailer-appropriate fixings you buy separately. KATSU reviews say bolts are absent, so plan ahead rather than discovering that on launch day.
How should the strap sit on the drum?
Flat, with even wraps. A twist or fold is a common jam point and loads the edges of the webbing instead of the full width.
When is freewheel allowed?
When the strap is unloaded and you are paying out for adjustment, not when the boat is on tension. A UK review of the KATSU warns that freewheel under load lets the handle spin.
Why must I keep hold of the handle?
Until the pawl engages, the handle can spin back if freewheel is selected or teeth skip. Keep hold until you are sure the pawl is seated.
How do I know the pawl is holding?
Feel resistance in the crank direction you want, with no free spin backward under load. If the handle runs free, stop and reseat the pawl before you continue.
What do I do if the strap folds or the gears skip?
Stop, reduce tension if it is safe, flatten the strap and inspect the teeth. Do not force it, and do not add people on the handle.
Can I leave the boat on the winch for the drive home?
No. Move holding to a bow chain and straps meant for road restraint. The winch is the recovery pull, not the motorway tie-down.
When do I stop and get a different winch?
When the frame or teeth are damaged, when your load exceeds the stated figure, or when you need a brake this category does not offer.
