D Ring Repair

Steve509926 · 16 September 2023, 11:15

I know someone will have had this issue before, so I thought I'd ask how did they repair it.

The bow D ring is tearing the pvc and I'm sure it will completely come away sooner rather than later.

I'm tempted to bond a new strap over the existing one with a round securing patch bonded over the top. Or would you take it off and start afresh?

Ideas and suggestions on a post card to..........

Hmm that's a pain. If your SIB was 15yrs old I'd say with heat, solvent & prising get all that off and glue on a new assy like this...

But your SIB is quite new and the glue is going to be sound so you have to be super wary of damaging the tube.

Yes DIY building it up reinforcing over the strap then reinforcing over the the whole lot is probably the safest and neatest job.

Is that a lifting bridle you've made to minimise this issue?

I must say stopping this happening is a benefit of the particular bow trolley I have as it both hooks onto the bow handle but also takes the weight on a couple of support tubes that are under the bow floor area.

If it were me I would tidy that up and as you suggest put a strip/patch over the whole lot.

Also if you have D rings on the Front of each tube lowish down. I get a short piece of rope with a loop in each end and pass it through each of these D rings, then through the centre D ring and then when you pull you are generally pulling on 3 points on the boat. Spreads the load a bit

I’d sow up the tear then patch the over it to strengthen then a patch over the lot as near as the original

It's a bow bridle I made, can't recall if it was PD or JS who had one when I first saw it.
It is to take the strain off the bow ring when I'm moored up and using the painter (as per #4)
The stupid thing is, I never even thought about using it when I winch Redneck onto the trailer and that is definitely when the damage has occurred.

Great idea. It may be a dumb question but, any particular thread?

Yep I’ve always done it but not tempting fate by saying more than that but by using three points of contact all taking the strain at the same time and deflecting the pull through 90 degrees ish half’s the strain you can also pull off the transom if that suits.

Something failed but without pulling on it myself, I sure can't tell if the entire part is about to fail. If in doubt, rebuild it. A heat gun will remove any glue holding power.

Another thing that is good to do is release all tie down tension while on the trailer for storage. If you have carpeted trailer bunks occasionally spray them with silicon lube. The difference in friction is substantial.

I used the heck out of my bow ring deal from having my anchor bridle pass thru it, pulling the boat around solo, to using a front cart, and never had a problem.

Personally I am not a fan of poly rope for much of anything, other than say a drift line with a buoy at the end for scuba diving. Almost impossible to tie a solid knot in a braided poly line, nor does sliding it inside itself hold well, so I would not trust it for anchoring or any kind of mooring. A good nylon bridle is not hard to tie or braid onto the boat.

I’d use a heavy duty thread found on eBay always worth having if you get a large gash in a tube before patching

I eventually did the repair to the bow D ring assembly.
After stitching the tear as JS suggested, I overlaid the existing D ring strap with black webbing wrapped and bonded in PVC (1st pic). I then overlaid that with another strip of PVC (2nd pic) The repair was then secured by bonding a securing patch over the whole assembly (3rd pic)
I decided to do the repair in black pvc as I couldn't buy faded red (tango orange) online!
Pleased with the outcome, looks good and hopefully it will last.

Fenlander · 07 October 2023, 20:08

Looks neat.

Nice result - black was a good move. Not tango orange - Ex-RNLI Orange. 10% slower than Go Fast Red but holds it's value 20% better...

Top job Steve as I would hope it to turn out now sort why it happened job done.

Steve509926 · 07 October 2023, 21:59

Thanks guys, I'm really pleased with the result.

I'm sure it happened because I winched Redneck onto the trailer by the D ring and didn't use the bow bridle. It also doesn't help that the bunks and Redneck are dry when I've done it.

So from now on its winch using the bow bridle and have a bucket of water to wet the bunks.

Looks a tidy job that Steve. My D ring was starting to let go on the previous Piglet. Probably due to pulling on it with too much weight in the boat. I’m tempted to beef up the new one before it starts to go.

chipko · 07 October 2023, 22:13

Neat job there Steve.

Winching a sib onto a bunked trailer is a killer for any bow ring to be honest. Reckon it’s better to go in deep with the trailer so it mostly floats on then haul the last bit by hand. [emoji106]

jeffstevens763@g · 07 October 2023, 22:51

The key is to have the pull on the side rings deflected through the bow ring which lessons the pressure so your pulling on three rings when I pull my boat on only me is out of the boat, I throw water on the bunks first or spray with ptfe to help. The other way is to pull from the transom as gurnard did with his 420 quicksilver

Steve509926 · 07 October 2023, 23:43

I don't often dip the trailer in the water, I tend to use the transom wheels to bring Redneck out onto the slip/beach before hauling it onto the trailer. Perhaps I should now reconsider doing that.

JS, do you spray the PTFE onto HDPE bunks? I presume it has no reaction with the PVC tubes?
I know some use silicone spray on carpeted bunks, but I'm sure I've read somewhere that PVC is adversely affected by silicone.

I was surprised at how much 2 part adhesive I used for what I would consider a small job. 125ml tin plus activator. Such a small amount was left over it wasn't worthwhile keeping.
