Started having a look at my powerwinch a few days ago courtesy of some "interesting" noises at the ramp last time. What started as someone having omitted the required washers for the roller bearings to run against some time ago >:(, escalated into a change to a dual line pull set up with a new winch cable and a re hash of the safety chain set up.

If it comes off now, it's really turned to custard.............Just call the insurance company type custard.

Interesting. One learns about the anatomy of the Powerwinch if one forgets to include all the bits or in my case if one does not use it the way it must be used.

Tightening the black knob is definitely NOT what you do first and when you do tighten it only the barest minimum necessary for the winch to engage. In fact last time I used mine I actually used the hand crank to "give it a hand" at the peak load time using a double cable through a pulley block with hook.

The Tinka chain set up means the Powerwinch is not used to hold the boat, it just sits there.115197

PS I wonder how long before the blue bit gets knocked off at the ramp?

Wondered that myself Chimo but it wasn't that expensive - about the same price as the much shinier stainless turnbuckle in the aft chain that has been there since I bought the boat. To get it off they will have to punch the pins out of the hammerlocks - hopefully that will be enough to stop the honest ones.

I had never dismantled the winch - just gave it a spray with lanolin. The rear thrust bearing washers were both gone and the bearing had deformed into something that looked like a miniature wheel bearing allowing the teeth of the gear that meshes with the motor gear to move across far enough that it was starting to run on a section of the motor cog that didn't have teeth - hence the "interesting" noise. The guys at Crawford's had told me about only tightening the black knob just tight enough that line was retrieved and then tighten once the boat is fully retrieved. It's surprising the winch has run as well as it had for the four years I have had the boat - Victory on a single line pull - no crank handle.

Yes when I had to replace the sixpence sized bearing the mob that sell the powerwinch were adamant that one must engage the electric motor with the switch and as you say (Crawfords) first and then only tighten the thrust bearing "just enough" to wind the winch. I have left the hand crank in place and it amazing how little effort it is to wind while the winch is working but my goodness it makes a big difference.

In truth one would have to say Powerwinch is great but the tiny critical bearing is really only "just" adequate but OK if your careful and give it a hand at peak times. Given that I don't drown my brakes my peak times are "substantial'.

But really whats the worst that can happen next? Being stranded on the ramp with a jammed winch, tick, been there done that; hence the desire for a boring ramp extractions!

By the way stainless turnbuckles are IMHO not educks guts as they undo too easily unless you wire tie them cf to the old gal units that just seem to stay done up

I had one of those powerwinch things I can only imagine how slow it is with a double up :-?
Later with help from a friend built a starter motor one, whoohoo, no time for a coffee and donut with that one
Dismantling the clutches and cleaning them with some solvent occasionally helps them from slipping
Anyway, looks well secured :)

Yeah. Will see how it goes. Can always go back to a single line pull or just order a pizza. The starter motor is on the agenda when this thing dies unless I find a small stationary motor at the right price - they retrieve scary quick.

I don't understand this setup.
There are 4 connections there,
- cable from winch
- chain from winch post - primary safety chain
- blue bar (whatever that sharp object is), why is it there? taking the slack out off the main safety chain? so boat doesn't move upwards?
- another chain with double anchor to main frame. Whats the point of this? safety in case the winch post brakes to stop boat moving forward? surely that twisty stainless bit is not going to hold the boat in an accident

We all know that bow U bolts aren't rated don't we. Most are 10mm that reduce to 5/16th or 8mm at the bolt/nut connection. There are bigger, 12mm with 3/8th10mm bolt, but no rating
Placing confidence in this connection without due regular inspection inside anchor locker can have a sudden adverse effect on the operator when it decides to let go.
Placing a tie-down load on this point without taking into consideration the flexing effect of the trailer while travelling can fatigue it over time.

Don't get me wrong Scottar that is a nice setup, I have a similar configuration but with turnbuckles etc, and only a hand winch, drive on 99%.

My bow U bolt failed just after xmas, one side of the U bolt snapped whilst on the way back from Horizon Shores.
Luckily the other side held, but it bent due to turnbuckle tie down pressure during the trip.
If it broke as well the boat would have relied on the transom strap only to secure to the trailer.
Lucky is all I can say.
Just pays to check the little things that are really and mostly overlooked.

I know it is a bit off topic but thought I would share as is sought of related.

Why is there a need for a turn buckle at all?
You can position the mounts so that the chains are the correct length without having to stress the shit out of the boat with a buckle.
Weakest part will always be the boats cleat especially when preloaded with stress all the time.

I really can't understand some people's logic.

It is a safety chain to stop the boat drifting backwards or forwards IF your tie downs fail.

You are pretty much on the money with your guess PROS. The blue object is called a ratchet binder or ratchet dog and is effectively an industrial size turnbuckle - the sharp bit is the handle that is used to do up/undo it. They come as standard with hooks on the end and are used to tension transport chains - those got removed. It's there to stop the bow bouncing around and stop any aftwards movement as the chain to the post can't be tightened with any sort of device with any strength due to length constraints. The aft chain is not only a safety but shares load with the winch post during braking - there was a thread on here a while back where someones winch post had let go and the boat had ridden forward. I agree that there is a chance the stainless turnbuckle won't hold - hence the continuation of the chain with a shackle.

I definitely think it's worth having extra chains to stop the forward and backward movement if something fails but I took away the turnbuckle and made my chains suitable lengths as I didn't like that much pressure pulling at the boats U bolt all the time. As has been stated the boats U bolt fitting on the bow of my Fibreglass boat would be the weakest link.
I definitely think it's worth having extra safety chains after my winch post snapped at the base between 1770 and Ipswich last year and I didn't realize until I was on my driveway and the tie down strap was the only thing holding the boat on the trailer.
A lot of you guys on here inspired my new safety chain and winch post set up. Great to be able to get such good advice and a variety of opinions from other people's experience.

Certainly worth thought Jim. I am aware they aren't rated and it just so happens that the bow U bolt has been inspected recently - out of the boat courtesy of the sika failing and the bow block needing to be replaced because it was wet ( that was a whole different misadventure - 3 days in a hole with multitool and fibreglass) . It is a 12mm bow eye and I am mindful of not over tensioning the dog. I just wanted something with a bit more strength than your average turnbuckle. In a "real accident" nothing anyone straps to a trailer that weighs as much as these sorts of boats do is going to stay where we put it courtesy of shock loading but I have done what I can.

The logic comes from having spent time at sea Jack and seeing what the smallest bit of movement will do to a load restraint. If you can get your chains tight enough - all good. From experience I know I can't without some form of tensioning device - even if I did stuff the galvanizing on the trailer by moving the mounts.

As far as winches go if a 712 won't pull the boat up on a single line there's something wrong with your** trailers.

Also if you have to start the winch before engaging the clutch then you will need long arms to do it while standing at the back of the boat pulling the string.

Extra chains? Don't trust your winch stand? GET A STRONGER WINCH STAND

** Assuming the boats only weigh a couple of tons.

Fit a hook to the front of your trailer and you do whatever you have to do either from the front or back and still keep tension on the bow with the rope while you attach the winch hook etc etc .

I don't drive on as I choose not to and launching and retrieving the Vagabond is an easy one person job using hook on the way up and 8 on the way down.

I have a 912 not sure about the others but given that my winch drags the Vag almost the total length of the trailer using a double cable was the least I could do to half the effort.

At 4 Ft/Min no load and probably closer to 3 Ft/Min loaded with a double line, 7 Minutes to pull 21 Ft, I'd kill myself before doing that.
I don't need no special hook, it's easy I just pull my string & the winch pulls the boat up.

Some say it's an overkill, but rather than having 4 ton rattling around on a trailer for a 1000km's on our great so called national highways.
I'd rather have piece of mind that the whole rig is rigid and the trailer / boat act as one.
The red V blocks work really well and hold the boat snug in place.
I did realise I had to put locking nuts on the turn buckle as it would always rattle loose.
I also tighten down ratchet straps at the back which also stops the trailer flexing

Wow. A lot of punters on here really worried about their boats falling off the trailer!

I use 2 lengths of sailing rope at the rear that tie the cleats to the trailer. up the front 2X 12mm formed eye SS snap hooks. One on the winch which has 5000kg rope and one on the safety chain. The clips have a breaking load of 3000kg. which is enough for me considering that is twice the weight of the boat plus my safety chain isnt rated, the welds arnt rated, the winch stand isnt rated, the stainless bow eye isnt rated. Thats enough for me and you can remove/connect them in 5 seconds.

11-02-2017, 07:29 AM
Certainly worth thought Jim. I am aware they aren't rated and it just so happens that the bow U bolt has been inspected recently - out of the boat courtesy of the sika failing and the bow block needing to be replaced because it was wet ( that was a whole different misadventure - 3 days in a hole with multitool and fibreglass) . It is a 12mm bow eye and I am mindful of not over tensioning the dog. I just wanted something with a bit more strength than your average turnbuckle. In a "real accident" nothing anyone straps to a trailer that weighs as much as these sorts of boats do is going to stay where we put it courtesy of shock loading but I have done what I can.
Been there and finally found the leak I couldn't locate, pulled the eye out and found the threaded section had rusted away to about half it's diameter allowing water in behind the wooden backing plate (glassed over so looked good from inside the anchor well) and the water then finding it's way down below the anchor well and into the bunks via a very small hole that I couldn't find even using a flexible hose camera. Replaced with a larger eye, backing board replaced with seaboard and a SS backing plate to cover a much larger area of the bow as I realised there was a lot of stress on a small section of the bow. I now remove the bow eye when I do my trailer bearings, give it a good inspection and clean up and new sika, doesn't take much longer in the maintenance schedule.

I also have a small chain at the rear but I have it connected into the shackle to stop it undoing but on long trips I will now put in lock nuts.

Another idea is that I'm pretty sure that Power Winch state that the winch shouldn't be the primary holding down point for the vessel. I would think if the rear of the boat is well secured there doesn't need too much more at the front.

Chimo
11-02-2017, 07:57 AM
Agree with you re the Power Winch as a primary holding point. All mine does is sit there with no load and the hook in the bow eye just to have a place for it to hang.

Having a two tie downs and two transum tie downs is a great idea. The issue is to remove a signal point of failure. The eye cleat which everything connects to is your single point. Rated tie downs is the way to go

1. The stress on that single point of failure with that bridle setup would be chronic and certainly nothing any single UBolt of that type and that purpose was ever designed for, nobody should be rushing to duplicate that setup thinking it has any sort of safety improvement.

1. I don't think the OP, or anyone else posting in this thread (whether serious or banter), is under any illusion that the 'bow eye' is not a possible single point of failure. The standard setup for some of the better brands have involved fore and aft chains with buckles for years. Many would have seen bow eyes fail, but I would bet just as many would have seen which posts fail. One single chain off the which post doesn't do much good in this case. A secondary chain aft off the bow eye is a good idea IMO. The ability to snig them up is also a good idea IMO. Sensibly applied tension via the snig to remove boat movement from an 'A' type securing arrangement removes shock loading induced from even small relative movements between boat and trailer. I think the OP has more than demonstrated his understanding of this, let alone his capabilities on this site over the years.

2. Nothing more to add, and wouldn't know the OP if I fell over him. Just seems very silly to use a numbered bullet point for a one sentence/paragraph reply, and hence I wanted a #2.

Yup.....an absolute cracker of a hussar:P

You girls on this forum sure seem to appreciate my love of hussar don't you, the other red meat!!;D;D

Just to get back on topic for a second, I was wandering around the boat ramp yesterday and starting looking at trailers, then kind of wondered why winch posts are all sloped forward at the top, is it for looks, or maybe just because that how it is always done? How about, if the post was angled steeply back at the top, so any hard braking force would be trying to push the post into the drawbar, instead of trying to snap it off? sound feasible? or did the extreme heat here just frizzle my brain??

Plenty of custom and semi-custom alloy trailers built with posts like you suggest Noelm. Seen some very large HDG trailers with A frame posts for strength too, but rare. Otherwise probably tradition why how they are, plus fits in better with stem slope, plus simplicity, hence cheap too. Slightly bigger weld area/footprint helps with strength too.
Cheers

I have always thought it would be good if glass boats had 2 u-bolts instead of only one. Large plate boats often have two points even though its one welded bracket with two holes. Surely a bit larger foot plate and a extra u-bolt wouldn't be hard at the build stage.

Yep, might be a good idea, I can see where Satnav is coming from, you can attach 10 chains, shackles and turnbuckles, but in reality, all that secures the lot is a cheap (possibly Chinese) stainless ring, with a 8-10mm bolt and nut on the inside, that said, if you hit the brakes in an emergency, and the winch post snaps off, a turnbuckle is not likely to stop a couple of tonne of boat once it gets moving! but, having nothing at all has got to be worse....

Not sure what you mean Noel.......;).

Yep - there is a single failure point - that I know is in good nick and is capable of towing the boat (not mine personally) at 20 plus knots on the plane,in offshore conditions from the Cathedrals to Manly so I do have some degree of faith in it. I can't, without the installation of a second bow eye - let's not go there Gav - I had enough fun with this one, do anything about that. What I could do is make sure that the hardware in place to secure the boat was not going to be what let go. The set up is only marginally different to what has been on the trailer for the last eleven years - just a "bit" stronger and with separate shackles for each chain. Should the winch and transom tie downs have failed with the way it was set up - the boat would roll about 100 mm or so before the chain stopped it even though the assembly was tightened with the turnbuckle - I wasn't happy with that. Both the binder and the turnbuckle are only tightened by hand (not by using the binder handle) so the chains aren't applying massive amounts of force unless other gear lets go first.

In reality the post was a tongue in cheek show and tell - not a tutorial (don't recall saying this is the way you should do it) and as with all things on the intermanet - not to be taken as gospel. People should secure their boats as they feel comfortable doing - after all, it will be their insurance and their conscience at risk in the case of an accident. As for those of us that suffer with OCD, it's a horrible thing to have to live with.

Actually went for a run to Tipplers for lunch today - lets just say I am a lot more comfortable with towing my trailer the way it's set up than I am being anywhere near some of the set ups in the parking lot while on the road.

Happy travels

On a side note Scott<

How was the lunch food quality? You or your didn't happen to have the snapper fish and chips did you?

Up until last visit by us we were very happy with the quality but not so last time. I'm hoping that this was an abortion and that the quality of food is back up to where it used to be.

Perhaps we could also conclude that the chains have run their race too?

Just grabbed some bacon and egg burgers and a plate of chips from McClarens Landing Chimo as there were about a million people lined up at Tipplers itself. Was a good feed for what it cost given the location.

The chains - yep, all done up tight.
