What happens when you revers the trailer?
In the uk you have auto revers which means the brakes will not work going backwards!
I do remember when I first started towing years ago you had to flip a leaver over to stop the brakes coming on when reversing, is this what you have?

Another aspect to consider is the car
Last weekend we were with 6 RIBs of 5.5m to 8.5m size at the Baltic. Steep ramp, and with a RIB on the trailer and the trailer on the hook and not fully down the Landy's traction/engine/whatever control decided to enter panick mode. There was the rig, close to the water but not close enough and no power left...
Funny thing, and my new argument for mechanical controls.

The winch handle is removable to stop broken arms & smashed teeth if it all goes tits up. Here's the drill:-
Reverse to bottom of slip (in low box)
Take weight off safety chain with winch & remove safety chain.
Remove winch handle
Give boat a shove & control descent using winch brake.
Recovery is a reversal, I always make sure the safety chain is attached to the eye before pulling up the slip.

Once the boat is off the slip, it's secured to the trailer with 3 ratchet straps, 2 at the stern through the towing eyes & 1 at the bow through the bow eye. The safety chain & winch strap play no part in holding the boat down. If all the straps failed or some numpty forgot to put them onthe safety chain would allow the boat to roll about 50mm back off the trailer & then stop it.
What he said.

Idea is not to tension it; it's a backup in case the primary tensioning device (i.e. ratchet strap or winch itself) fails.

That said, I have my chain fairly long, and cinch it up shorter using a steel hook through one of the links.

Classic. Although the back doors both nearly closed on him, which could have been bad!

Surely you leave your car in first not reverse on a slipway? In reverse if it is steep enough worst case it will actually start the car.

In fact it should be weak enough to snap after applying the brakes. A trailer with the brakes locked on disconnected from the tow hook but chained to the car could be messy.

The chain there talking about it usually fixed from your winch post to the bow eye.
This way if the winch fails your boat won’t just roll off the back of the trailer on the slipway.
Both are important. Easy in the haste of hooking up the trailer not to connect the ball properly and then at the top of the slipway it disconnects and rolls back down.

I've only limited experience with braked trailers - but surely the handbrake works in both directions (as opposed to the brakes when driving). Otherwise you are towing up a hill and loose the trailer the cable pulls the brakes on, snaps, and it rolls backwards? or if you park on a slight slope and apply handbrake then disconnect the car it rolls away?

Just so you know Hightower - the slipway is pressure washed EVERY month and then treated with "Ecoslip" a marine friendly inhibitor - not sure that isn't an oximoron. We are of course subject to the tide conditions, but strive to ensure that we get as low to the bottom of the slipway as possible. This was never done before I (KB Dry Stack) took over the management of the slipway. So I think we do our bit!

don't think the cable needs to be strong enough to keep the trailer in line with the tow vehicle as with the unbraked trailers Just as long as it applies the brakes it can snap.
In Australia we must have safety chains on all trailers including those fitted with a breakaway system.

Hand brakes must also be fitted on all braked trailers although many don't due to brakes seizing due to rust. These hand brakes are often operated from the trailer (not the car) by a ratcheting mechanism and they hold the brakes on regardless of which direction you try to move the trailer. Admittedly many drum brakes do not work as effectively in reverse but it should be enough to hold the trailer if stationary.
