Leaking Tube/Chamber Repair

Matty75 · 29 March 2022, 05:10

Hi all.

Noticed the other day that the stbd-aft chamber on the Humber was slowly deflating.
Completed a leak-test and found cracking/small split of the Hypalon seam - see pics.

What would be the best way to go about repairing this, what type of repair?

Who would you recommend to carry out this repair?

Thanks.

Matt.

Hypalon patch and 2-part glue. 3 thin coats on each (patch and tube). Then apply patch. Good as new. Be sure the patch has no square edges. cut it into an oval or circle. It may be hard to find blue. you might have to get a gray patch and paint it with hypalon glue. Then cut it to size.

Hi there.

Thanks for the input, but unfortunately due to the location of the leak, a "typical" patch job will not be sufficient.

The area of the leak is below the waterline and with constant immersion combined with the effect of flowing water at 40kts, the "standard" patch will not last!

Cheers.

Agree, any repair done with a leading edge won’t last long. looks like you need cone redone. Humber or any decent tube company could do this. Put where you live you’ll get recommendations.

Not a fix but try scuffing the surface, applying multiple layers of glue (no patch) & allowing it to fully cure. You'll be surprised.

I use this sticks like poo to a blanket cut your patch so it has the smallest leading edge limited on width I know. If it fails it’s a easy and quick repair until you get it sorted properly.
