2WDs and slipways

Does anyone have any tips on how to get the most out of a 2WD (front-wheel drive) when pulling a RIB out of the water on the slipway.

My combined RIB+trailer+engine+accessories package will probably be within about 200KG of my cars kerb weight (Volvo estate).

I am wondering if anyone has any practical tips other than loading the family onto the bonnet or thumbing down the nearest tractor / 4WD.

Does traction control make much difference? How about load distribution in the car / RIB? Pulling with a rope from the flat!?

I had the same problem, although my RIB is not as big as yours. I have a Rover 418 Turbo Diesel. A lot of the slipways that I use are quite steep and many have sand at the bottom so it was very difficult for me to get anywhere near the water. It was fine launching but recovering I used to have tyres screeching and the clutch burning as I attempted to pull the trailer out of the sand and then up the slipway.

I now have no problems at all even with a small car. My solution, was to buy an electric winch. I bought a 4500lb electric winch from www.trailerpartswarehouse.co.uk and an adapter that attaches to the tow bar. All I do now is put the hand brake on, chock the back wheels and attach the winch. Then I just sit back and push the button and it effortleslly pulls it all out without me lifting a finger. It cost me about £300 for the complete setup but I reckon I have save dthat already on tyres and clutches.

My friend has a 6m RIB and when his 4 x 4 wouldn't start I managed to pull his RIB out the water with the winch with no problems at all.

put a tow ball on the front, makes it easier to move the trailer around in tight spots too.

if it`s legal

before putting a tow ball in the front check if it`s legal.
In Sweden it`s not, just because of the reason that in a car accident you will cause a lot of damages on the other car and there is a bigger risk that people getting hurt.
Same thing if you have the tow ball in the back, ther is a bigger risk of getting wiplash if someone hits you from behind.

Regards

the slip i use is very steep and has a step at the bottom with plenty of green stuff on it. my rig weighs about 1700kg and my only option is a decent sized 4x4. We have rescued several people including smallish ribs with biggish fwd cars (saab 9000t) when theyre on the slippy stuff or fallen off the step. The only people who do manage it use ropes or even better slangleys winch. But then there is another problem with that too i saw one rib owner in tears when his rib on a rope flipped up and ruined his prop and gearcase of his new honda 4stroke.

2 WD

I use a rope and am very careful. No problems so far but my set up only weighs about 400 Kg.

I have 4WD but am loathed to stick it in the water so thats why I use the rope.

Most people just drive there cars in the water and don't care about it.

If you are worried about getting stuck on a steep slipway find another one that isn't so steep.

I use a couple of chocks whilst I am launching and retrieving my boat and as long as I don't rush it or be rushed its no great problem.

I've never had to use 4 WD yet.

Front wheel drive cars don't work on slipways. Full Stop!!

You need rear wheel drive, or 4wd to be effective on anything other than a dry, gently slipway.

Can never see why anyone put their car in the water though, absolutely unnecessary if your ri is set up well and correctly balanced on its trailer.

I disagree with the first line there, Windchill

I've only got stuck on the bottom of a slip once so far, and that was due to it being heavily weeded, so even a four wheel drive would have had issues!! - pretty sharp inclination slip that our loadall at work will happily slide on too

When launching, the boat is very keen to leave the trailer even on a shallow slip. I normally back the van down the slip till the back tyres are just out of the water - I then tip toe around the back of the van without getting wet, and climb over the bow onto the boat. Drop engine onto shallow mode, and bung into idle ahead - reach over the bow and unhook. Drop engine into neutral, and the rib slides nicely into the water every time.
Once on Neyland slip, I undid everything, went into neutral and the boat didn't move, so I thought I'd get off and have a look - just as I jumped off, the boat launched..... it was a very quick jump back on board!!

As for picking it back up again, I do the same thing mostly in reverse..... on the slipways at Milford and Neyland, they're concrete, with very little/no stones, so I am happy to use a bit of power and drive the boat onto the trailer. If there is weed/debris visible, I normally jump into drysuit, overboard, and winch the boat onto the trailer as opposed to driving it on - I like the ali prop with its black paint on it

When going up the slip, I generally take bite with the clutch, and let it slowly pull up not riding the clutch too much, and then engage clutch fully as soon as there is enough power in the engine to pull it up straight. Sometimes there is a bit of loss in traction, but careful control beats that mostly, and it pulls the boat up everytime. I'd guess the setup is around 900kg all in - my previous van didn't weigh too much more than that I don't think, but the manual reckoned it was good for a ton in pulling

Although I'd love a 4wd for weedy slips, we just don't have many like that around here, so 2wd is just fine
