ripped off d rings

Went to check over the boat at the weekend to find the end d ring hanging off. it looks like the fender rope has SHRUNK to such and extent it's torn the d ring patch off.

is this usual?




boat was retubed about 5 years ago.

ill try and dig out a pic

If the D-ring had constant pressure on it, then yes it is normal. That is also glue failure as shown in the picture. The black seems like it is getting hot in the sun too, which will lead to failure quicker.

Is the boat covered when parked?

that looks odd if the rope is under tension that much how would you get hold of the lines? agree with glue failed & cover

I couldn't believe how much it had shrunk either!

It wasn't under that much tension when it was retubed and so I guess that's just shrinkage caused by salt and fresh water and the sun!

I'm going to replace both sides as a precaution and allow for future shrinkage I think.


Also not using 3 strand cord this time but double braided (and practice my splicing).


Any recommendations on a boat cover? I had a thin silvery hobby previously but it wasn't the best

That can't be right, the rope surely couldn't shrink that much, and if it did I'm not surprised the glue gave way.
That looks like @500mm shrinkage over @5000mm.

What's the other side like?

certainly "twangy" but nowhere near as much pressure. I'll cut it (later in the week) and post a pic of the gap between the ends

Who did the re-tube?

It looks like they've put the lines on for a boat one size smaller!

Specialised Inflatable Tubes

July 2013


When I bought the boat the tubes were worn V thin so I knew it would need to be done. Then one day I found the tubes had failed.

Other pics show the retube.


I've been very pleased with it

The lifelines on my boat had shrunk and where pulling the tubes out of shape but nothing like that.

The new ones I have tied on with bowlines so I can release tension if it appears, I plan to splice them on in a year or two.

Does anyone know how quickly rope shrinks? Mine is 3 ply.

for me humber had it right line loops that you can get hold of easy the sit ones are miles too tight and used cheap rope by the look, good job the glue gave way or you might of had the tube damaged

Which sounds like a great opportunity to justify a bigger engine.

Nylon rope shrinks because it is hydrophilic , my boat did this once when a did not allow enough slack on a new life line.



Cheers

Sunbrella is the most commonly used cover and material used for long term marine applications. Easy to sew if you have a powerful enough machine. Otherwise if you can find a shop that has your boat pattern it will be slightly cheaper than having someone custom make you one. A good cover pitched like a tent with no sags to pool water can keep 100% of the water out for years, then it will need to be washed and have water sealer re-applied.
