Pulling a Speedboat up out of the water

TCubed · Mar 10, 2012

Hello,
I'll soon be using my P38 DHSE to tow my speedboat. When I recover it and it's trailer (weighing in at probably 1.5tonnes max) from the River Thames the slope angle is about 20°. I assume low range, but which gear would people recommend?
I used to use a Dicovery I 3.9 which pulled her out like a breeze in low range 1 or 2 difflock on or off, but as that was a petrol, manual, V8 will it behave differently to the Range Rover?
Thanks

Loads of torque on the diesel, almost as much as the 4.0 V8, if it's auto it will probably pull it out in hi range but easier in low range.

I think you should be looking at some waterproof gear such as an anorak, wellingtons and maybe invest in some marigolds.

Hello.

No problem, I pull our 23 foot trophy up a slipway without going into low range, select D and it does not even break sweat and it would probably be about 2 tons.

That sounds fantastic - I knew they were great cars!
Any thoughts on rear end waterproofing, exhaust submersion? Actually on that note, what's the P38's rated wading depth?

500 mm

Squid minus turtle = wading depth of the hedgehog

That's still 498mm more than a Gaylander.

500 mm

I presume that's 500mm with the suspension raised to off road? To where on the doors is it waterproof?

Ah yes I have heard that. With that in mind then and regarding the high EAS, were I to park it in high and then leave it for ~6 hours, would it stay there? Or sink back down? I'm thinking of parking by a tidal river.

You can only find out by trying it, preferably without the river. Mine will stay up for a week, and my suspension's not bad either, but everybody is different.

dont know, im more a defender man, but saw a p38 get stuck in a ditch at an off road site, about a quarter up the doors, it was there for approx 10mins, everything electric on the car was going off, dragged it out, but it wouldnt start, apparently it cost a fortune to fix, because water got under the seat

Thanks for the info
Does rather beg the question of how Land Rover engineers failed to see this coming...

Why all the talk about water, my back wheels don't even touch it, reverse the trailer into the water, hitch the boat to the trailer winch and winch it on, launching is even easier, reverse in, the back of the boat is floating, lower the engine, start it and put it in astern, boat pulls of and that's it. If the slip you are at is as steep as you say you should have plenty water by the time the hitch is level with the water edge. After all its a speedboat with a planing hull, not a displacement hull.

Never used to get my truck wet when I launched my boat, I unhitched the trailer, clipped a winch on the tow ball and attached it to the trailer, then lowered trailer and boat into the water. I wouldn't rely on leaving a P38 anywhere near water, the suspension can adjust down as the result of high winds rocking the car, never mind the potential for air leaks.

Ah ha another good reason for mine being on coils.

hauled a dead Classic plus a Five tonne power boat out of trouble in Bosham last year without issue, just put in low range and off we went....
