Hypertext is hypalon?

Nauticool · 26 January 2010, 14:11

Hi all, have a narwhal 3mtr with 30hp outboard. Material on the tube says hypertext. Is this the same, and should be glued, as hypalon? Under the hull the black strip that seals the tube to the hull has opened by about 12" and once on the plane, between 25-30 knots,water comes in. What's the best way to repair this and what materials are needed?
Any help would be much appreciated...

Had a similar issue with my boat.

I used the Weaver equivalent of Zodiac "Universal" glue. Make sure the area is dry, and free of salt deposits. Clean the surfaces with MEK, lightly sand, clean again, then apply glue per directions (I used 3 coats.) Use lots of pressure when joining the parts.

I was joining the hypalon strip to aluminum, you'll be joining whatever fabric to fiberglass, I guess. Shouldn't matter with the universal glue.

Hope this helps;

thanks jyasaki,

What are your tubes made of? Ive never heard of hypertext before i bought this boat

My mates got a Narwhal and it PVC or PU or something, not hypalon.

Hypertext is an advertising ploy it makes you think you are getting a hypalon product when it is actually pvc or PU depending on size and age

Yeah thanks, polymarine say use thier PVC two part also. Does anyone know anyone that will retube this in either PVC or hypalon cost effectively? Don't mind travelling as I work up and down the country. Given the fact it's leaking water into the boat and air out of the tubes I think I could be wasting my time. May try inner tubes also. Cheers. Great site!

Speak to any of the usual suspects - you won't get a better job than Paul Tilley (above) - as to whether it's cost effective.......

I would still go with the Universal stuff. It's a urethane based contact adhesive, so should be OK on PU tube material. It supposedly works well on PVC (haven't tried) and hypalon (which is what I have.)

Lot of effort saved if you can have someone do the repair for you, I suppose. Might cost a bit more, though.

Might be worth a word with Kieron at Rib Shop, don't know where he gets his tubes, but the web site advertises re-tubes, and he is local to us! He did a good job for me, and didn't charge the earth

Ok I'm armed with polymarine two part PVC glue and lashings of acetone and mek, what's the worse that can happen??? Wil give it a good glueing tomorrow and let you know. Otherwise it's a retube, £1500+
trouble is I can't find another 3mtr rib that will take a 30hp outboard, 10ft is the max for free tender moorings here.

Where are you glueing it. You'll need somewhere warm and dry otherwise you'll struggle.

MEK smells great too!

Not half as good as the glue does chewy

yes it was warm and dry in my works workshop for 24 hours now it's back out in the cold. Hope it cures ok, says 48hrs on the tin but couldn't leave it in there that long. Seems to have taken quite well. The original glue had failed along a 2" x 3ft strip. Solid as a rock now
If the weather is not too bad will try it next weekend.
