Pulley system for sib or winch

daveyirl · Yesterday, 21:07

Hey all

I recently got a honwave t38 ie3 & a 20hp outboard

I posted a separate thread about manageable weights of sibs before . I am glad I got the lightest one !

So a couple of months in , I’d like some advice on a rope / pulley set up,

So basically I live on the sea so any solution can be permanent (albeit I can’t do anything below the high water mark)

At low tide I have about 40 meters. Plenty of large stones that make it awkward at the flat part then a bit of an incline where it is a bit more pebbly and loose.

It is no problem with 2 people
It is barely manageable with 1 - at low tide it is unpleasant and takes some of the joy out of the whole experience.

Some info and things I have to hand

- it’s not accessible by car really. The access to the sea is perpendicular to the driveway for cars. I could do redirect pulleys etc but I would be blind . It’s an option but not my preference
- I will likely get a small tractor or quad in the future for other reasons . Not ready to bite that bullet just yet
- I have a trolley (suprod - it is light weight) - rear wheels are ok . Castor wheel is more like a break ! Would need to replace
- I have a loan of some railblaza kayak wheels that I can buy cheap if they are of use
- I have heavy duty transom wheels on that are decent

So I’m looking for something to help make like a bit easier and am considering the following but would love some input.

- manual winch - are they super slow for a distance of 40m ?
Any particular ones that might be quick?

- electric winch - I’ve gone off this idea . Battery usage , being left at the sea . Just feels like hassle and if it is 40m could burn out ? Most I’ve looked at are not really built for that long a distance

- a pulley system - I have plenty of fixing points at the top of my access. My first thought was just to fix the rope to a point at top of access and have a single pulley on front of boat . If I do that using the transom wheels , how do I keep the bow up? Is there a better system ? I don’t really think I need more mechanical advantage than 2 to 1 and setting up multiple pulleys will take a lot of rope ! I can imagine getting frustrated managing more than 100m of rope.

- I could get balloon wheels which seem to make a big difference

Re the things above , the question the. is whether I can make it work with the transom wheels alone ? Keeping bow up somehow. Or clipping it to be but then where is the pulley ?
or if I need to use the trolley ?

I can use the kayak wheels either on the bow or on the trolley. Not sure if best way to attach to boat - I tried ratchet straps but when the going got tough the boat slipped off them .

Lots of details & questions but I’ve thought about it a lot. One important thing is to keep it as simple as possible . Given I’m at the sea , I want to avoid anything that takes time / fiddling around with.

What part of the process is giving you the greatest problem? The stones/boulders being too large for transom wheels to roll over... the steeper pebble part causing the transom wheels to dig in... lifting the bow at the same time as pulling being too hard work (or are you using the suprod trolley)??

An image with greater detail of the whole route at low tide might help (I did look back at the one posted when you asked re this in Aug).

Thanks Fenlander

Fair point about photos - I’m attaching a couple here . Can take more tomorrow .

In the photo with the ropes , that is getting to low tide . At low tide there is another 10 meters of similar terrain.

I’m not using the trolley. I’d need to remove the castor wheel and get some better solution for the front . At the moment it feels like the trolley is much harder work that just the transom wheels

The transom wheels need more strength to get over the rocks . I can do it , but it’s a big job . With 2 it is easy. I’d say if I had 20% more strength I’d be sorted . I would say the softer stuff is a similar issue in terms of struggle albeit I’m a bit worn out by the top.

The easiest thing for me to try / test is a pulley system - I’ve plenty of rope and a few pulleys. I’m just not sure the best way to rig it to keep the bow up or how to rig it if I am holding the bow somehow.

I haven’t done myself too many favours yet in terms of approach - e.g. At the moments I’ve been pulling by rope while walking up backwards . E.g. Would a harness or putting the rope around my shoulders help a lot ?

I should mention that I am keeping the outboard on the boat . It’s 45kg and I don’t want to be messing with it every time.

I'm still of the opinion that the easiest option is to separate the outboard from the sib and take them to and from the water separately. The sib won't be a problem on good transom wheels and the outboard will be manageable on a converted sack truck.
Pulleys, winches etc to launch and retrieve every time are, IMO, just going to be cumbersome and you will eventually stop using them.

I'd have thought a better launching trolley ,wider with larger diameter wheels & a good wheel on the front would be the best option. I've always found transom wheels leave you having to lift a significant amount of the weight as well as pull which makes for an awkward stance. With a good launch trolley with a good size front wheel & using a pulley system means you keep both hands free to pull with. The front wheel doesnt need to swivel as you can balance the boat so theres negligible weight on the front & the rope should keep the rig in roughly the right direction & if it does get out of line it's easily pushed back into line.
