Trolley wheels: how to stop the boat rolling back down the slipway?

[single]

+1.
The load is not huge if the slip is reasonably smooth.
Say 400lb boat and trailer, 1 in 6 slipway, 2:1 tackle even allowing for a fair bit of friction, 50lb pull should shift it.
The trick is mostly about using the rope to get a good pulling angle instead of working awkwardly while standing on a slippery slope.
The anchor point could be fairly small, like a metal ring secured by a few screws and rawlplugs? Or at most an M10 masonary fixing, no need for great big stakes?

Fine until a speedboat or bigger try and hoist from it

Nice ideas gents, thank you.

The trouble is that: a) there's absolutely nothing to tie a painter/winch-line to ashore, and b) the nose of the boat doesn't press down much on the front of the trolley - in fact it's a very neutral balance fore and aft - which makes for easy manoeuvering on the flat, but the boat will slide downhill if unattended, and I'm certain a braked jockey-wheel would skid too.

That said, a jockey-wheel would let me push from behind...never tried that, it could be the answer.

And when you stop for a breather it'll run you over into the water, pinning you under... ...this will happen when alone, at dusk, with no one around

I hope I can convince the club commodore that driving a steel tube into the top of the slipway is a good idea. I was thinking of not actually asking, but SWMBO frowned severely... [/QUOTE]

Why not ask the club to provide a post or ring for the purpose?

You might find you can scare them into providing an anchor point, for health and safety reasons, in case you hurt yourself using their slipway!

Nice ideas...but everyone at my club sails a boat they can easily manage, on the water and out of it...if they sail a two-man boat, they won't attempt to sail alone, or haul it out alone...

...and in that environment, there are already raised eyebrows about a non-competitive singlehander who's fitted oars and lazyjacks to a fairly classic two/three-man race-boat...

...and while I don't mind being the local eccentric, I'm not hopeful that they'd jump at adding features to facilitate my non-standard ways of sailing.

Besides, with all the wise practical advice I've received here, I doubt I'll need any help!

Don't ask.

Get a 2ft length of rusty scaff tube ideally with a flattened end. Knock it in when no one is around to just below the surface, cap it & cover it. Discover later and start using it as per Lakey's post. 2:1 should be enough if you can just move the dinghy unaided. The angle of pull and your footing should be better. You also have the option of locking the end of the rope and pulling on the middle for additional purchase.

Use an old locking main sheet block so you can stop at any time.

Good plan, thanks. I reckon the block and tackle is the winning solution, whether I have to be sneaky or not, connecting it at the top of the slip.

Thinking carefully now, I remember there are a couple of banks of small shingle to get past - not big, yard-high waves of the stuff, just gaps where the concrete has split and small stones have lodged themselves, creating gravel-traps.

That stuff can stop movement even when I've been making good upward progress.

I was thinking of using the 2:1 tackle as suggested, but including within its length a short second tackle (maybe 4:1 with smaller blocks and line) so that when I'm halted by the gravel-trap, I can 'change gear' and pull through the slower patch.

I'll find out by trying.

You'll get black-balled......

What a good idea, isn't that post #28

Sorry to anyone whose suggestion I may seem to have overlooked, especially if I 'discover' it myself later!

I'm usually as daft and obtuse as I am determined - I take a lot of persuading about things which ought to be obvious. But all advice is very gratefully received.

I'll take care not to get trapped and squished behind the boat freewheeling back down the slip, thank you!
