Electric Winch and extension rope - Page 2

Like I suggested at the start using pulley blocks, I would go for 6x rather than 4x but here is an example.

YIKES!

At first I was thinking just roll it over the beach with 49cm Wheeleez at the back, and some smaller ones at the bow, but the pictures tell a different story. There is not going to be an easy way to get it up that beach without front bow wheels, and a winch of some kind. Caspian type would be the easiest with a ultra low stretch line like Spectra. Duty cycle is going to be very important. The pull will not be great, but that is going to take a long run time. To keep the rope from being damaged you will also need to build a pulley system to put at the top of the berm to redirect the rope so it doesn't drag across the rocks. Otherwise it will need to be steel cable.

This is a 500lb (226kg) boat that has been beach launched over many beaches. Although there may be steep sections we never had to navigate a long loose gravel beach like that. Looks hard just to walk across.

Very handy bit of kit. I’ve got one of these

You need something on the top of the storm bank with a guide roller to change the angle of pull, a small A frame maybe that you can easily move back to the next bank.
What do others living/launching nearby do?
Making sure you recover at high may help but only with the easy bit.
Because longshore drift is putting the banks of shingle there they are loose packed I bet so no chance of getting the trailer onto them without it sinking up to its axle.
Ive not really helped much.

Many years ago we used to launch jet skis on a similar beach , we would winch the ski off its trailer onto a dolly (trailer with 6 large ballon wheels).
Then two of us were capable of rolling it down , but there used to be a diesel winch permanently fix on a concert slab at the top that was fine pulling up the ski on the dolly.
It didn't dig into the steep sections but the ski was higher up on the trailer, i think my set up is going to be so light at the front i could just pull it up while the winch is going to avoid it digging in.
The old fishing boats just used loads of plastic pipe and some of the huts still have old winches in them.

Im just going to test the small winch with my sib on the trailer if it does that then it'll do my possible bigger rib.
If not or to slow / hassle ill have to spend some money on a petrol capstan!

Hi windsurfer..

What i use is a climbing jumar. The thing mountaineers clamber up ropes with. Attach it to the winch tape..slide it up the rope.. winch in the tape.. unwind the tape..slide the jumar up the rope then winch again until back., Its easy that way so no need to tie loops in the rope etc.

This is a long link..but shows one..or if link does not work google “Climbing jumar”

In fact … You don’t need to buy a jumar either as there are knots designed to do the job ..google prusik knot and you will find out how to tie them. They can slip depending on the rope you slide them up.. hence why I use a climbing jumar..but at least you can try winch and a prusik knot to haul the boat up your long rope ..before splashing out money.... to see if the method suits you.

Prusik knot..

Went through this myself with jet skis and boats. Stay portable, as you are, or go bigger and into the marina.

The lack of any ramps is ridiculous, I wish the council would invest, there's a huge catchment area for enticing visitors in.

That is perfect for what i need , i had just mastered the aline loop as i thought i was going to need to tie it 40 odd time plus it would of added nearly half the amount of rope i actually needed!

Ive never understood why there isn't even a ramp into the harbour and everything is hoisted in , i guess that and the fact that there is no ramps nearby is all just about the harbour making money.

Another thought as I to am looking over all options to move a heavy future boat across the beach. Been looking at driving 2-3 wheels with either electric over hydraulic, electric, or air driven, and started running calcs and costs. Then this thread brought up another possible means, when pushing doesn't cut it. The anchor used as a pull point. Our beaches are generally sand, and a good anchor, like a Mantus, easily bites in. So the idea of a self tailing winch, wired to be remote controled, mounted at the bow, is intriguing and reasonably affordable, plus could be removable. First it would pull the anchor up from the bottom of the ocean, which has never really been a big deal though. Secondly it could be used to pull a boat up a beach. The batteries wouldn't weigh much with Lithium, and could even be augmented once on land. So the thought is set the anchor and start pulling with a third steerable wheel under the bow. A two speed winch could probably be used on high most of the time. Still thinking power driving the wheels is the way to go IF I can make it affordable.

Last year at new England bay we trialed winching my boat, outboard and trailer up the beach with a budget 12v winch, a car battery and a land anchor. It worked well. But was times consuming.

We looking into a fast spooling winch, but they cost alot of money. So we gave moved onto a forestry winch.

It will have its trial never month at new England bay.

I made the mistake and didn't take any photos last time. But after so much interest on social media I hope to show a full demo next time.

Hi Dd , my winch comes tomorrow and it looks similar to yours in the picture hopefully it'll do the job but not getting over excited! What forestry winch did you get and would be keen to see it in action..

Eye watering price tag though.

+1 used a lot for tree felling over a grand

Will post make and model of forestry winch next week.

Here are some photos from new England bay.

Getting back to rope and knots, can anyone suggest the best way to attach to the 3 d rings at the front of my sib to keep the pull even across the 3 points.
Cheers

The same way you should be anchoring, with a bridle that has two attachment points run through the bow one. That way if one side fails, or both fail the center point will hopefully still hold. I was going to take the line and weave it in nicely, but found the knots to be handy to use on land for picking the boat up, and if one side broke, the knot would hopefully hang up in the bow triangle doohickey. A figure eight in the middle forward formed a loop. The length was set to clip to the anchor crate with a carabiner for storage. The carabiner also got used for clipping to the anchor line when deploying it. My photo of the Zodiac above shows it as the white line. Can't remember now if I used 1/2" (13MM) or most likely 5/8" (16mm) line, but it was larger than the 3/8" (4.3mm) anchor line.

i splice my two side ring ends then pass the rope through the bow ring with a shackle connected to the bow line, my trailer winch attaches to the shackle to. pics of it on my excel 435 build thread

So Windsurfer, have you found a solution to the steep shingle beach recovery yet?

Windsurfer · 09 September 2020, 09:18

Yes I did ! I’ve been meaning to post the pictures and the set up but haven’t had a chance yet !
Will post something later this week , but really happy with the results and able to have a bigger boat !

Windsurfer · 12 September 2020, 18:42

This is how i have been able to launch my new set up at my local beach..

I use a small piece of 100mm soil pipe under the keel to take the wheels on and off , i can launch and recovery myself but its much easier with 2 and i don't go out alone anyway.

The rib is a 3.8 quicksilver alu hull and a 25hp 2 stroke (about 170kgs with just fuel and outboard).
