Which hand winch for pulling heavier SIB up beach?
Looking for some advice on a suitable hand operated manual winch. In the near future I will have a heavier SIB and will need some mechanical help to pull it up a short pebble beach. Gradiant probably 15 deg but there are a couple of short but steeper banks.
Our current boat on launch wheels (probably around 35kg gross) is a doddle for my wife and I to pull up but a 75kg + SIB will not be so easy. We have wide wheels as here:
http://www.rib.net/forum/f8/beach-la...tml#post479701
...which roll brilliantly over all the different beach surfaces and once it's rolling it moves fine but a heavier boat will be too much for us alone. We park our Landy on the beach so the winch could just be secured to the tow hitch.
Any ideas please?

That could be dangerous.

You might find that a 'drum' type winch doesn't have the capacity for a decent amount of rope / cable.
How about bolting a capstan on the hub of one wheel of you LR, jack the wheel up, put it in low-ratio / 1st and Bob's your uncle!
Another option is a ground anchor, pulley and driving the LR off down the road, pulling the SIB up the beach.

Did think of that but I'll just use an extension rope to the winch cable for the first pull then discard that, unwind and hook the boat directly on to the winch cable for the remaining distance.
Really don't want to get involved with jacking the Landy or driving it due to the beach/road/railway situation it would be tricky!
Just need ideas really for winch capacity required and recommendations online.

trouble with all hand winches is that the cable drum will be very small, unless you go for the "tirfor" type, you call try a small electric demountable type that fits onto a tow ball, just depends how deep your pocket is and how far you want to pull it

I use a boat trailer hand winch at home mounted to a post. I have replaced the standard cable with stainless steel cable as used on sailing boat shrouds. I have about 30 m of cable on the winch and has workewd fine for over 25 years.

How small are we talking Chris? I have never used one apart from the usual trailer type when I had a RIB.
I need to measure the distance but probably 30 to 40m so no problem spanning most of it with rope.
It's such a relatively small weight and in keeping with my preferences for doing things the simple way I was hoping to keep it all manual especially as most of the cheaper electric winches have a fair bit of monkey metal and plastic inside...

am i missing something, if the landy is in range of the length of cable of the winch, just tie on a bit of rope and back the thing up? If needed chock the wheels on the trailer and drive the landy back down do the same again?

Possibly - as per post above: "Really don't want to get involved with jacking the Landy or driving it due to the beach/road/railway situation it would be tricky!"
There is no space or safe war to drive in the correct direction due to the beach/road/railway/parking situation etc. I don't always use a trailer anyway, the boat would be moved on launch wheels.
Really want to stick with the winch idea...

With the relatively light loads load you are dealing with why not just use a rope & pulleys?
Like I mentioned in yesterday in another thread, be sure the pulling force is applied directly to the legs of the launching wheels and not to the bow handle!
Also, even with what seem like light loads, never use a tow ball as an anchor point for winches and tow straps. This has caused many deaths.

That's an interesting thought. If I could half the effective load then we should be able to manage that. We've got a full adjustable tow hitch set-up on the 110 so no issue with finding a safe anchor point.
Can you elaborate on what would kit would actually be needed and any more tips on doing this in practise? - I dropped out of physics A level after a few months brain-frying...

for any pulley system count the number of times the rope goes back and forth(excluding the one you pull on.)
thats both the reduction in effort and the increase in length of rope you'll have to pull.
2 = 1/2 the effort, x2 the distance to pull (pull 2 feet boat will move 1 foot)
3 = 1/3 the effort, x3 the distance to pull (pull 3 feet boat will move 1 foot)
4 = 1/4 the effort, x4 the distance to pull (pull 4 feet boat will move 1 foot)
etc (and yes i know its not exact, friction etc will change the effort but its only a guide)

This looks interesting and might work well in my situation?
Video is a bit cheesy/bull*****y but you get the idea.

This thread makes me want to get back on my boat mover project. I started to convert an electric wheelchair into something that will drag my boat around on the beach...via remote control. Unfortunately remodeling/upgrading/tiling the bathroom takes priority.

We did have the boat out twice over the 4th of July weekend
I also spent three of the four days working on the house. Along with felling and bucking a few trees tonight.

Anyone help with this some more?
Recommend a hand winch or what capacity I need or tried the Skywinch or how to put together the pulley thing PT referenced above?
