I have a WalkerBay hypalon RIB
. It's maybe 10 or so years old (I am the second owner).
lives inflated on my foredeck.
I just put it into service
for this year and I am noticing a whole bunch of small blisters
at the bow where the hypalon sits/touches the deck
. This area is not exposed to sun.
are between about 1 mm and 5 mm in diameter and domed outward. They seem to be air filled. It looks like the outside coating of the hypalon has detached from the underlying fabric
and air pressure from inside the tube is pushing the detached 'plastic' coating out to form a bubble.
Is this a normal hypalon failure mode?
Can it be fixed without a giant patch ? The total area covered is about 2 sq ft.
I have seen the occasional bubble in other areas but that is just the occasional blister. The area that I am concerned with has maybe a hundred tiny blisters.
I suspect that as these blisters fail, the leakage rate from the tubes will go up. I have no idea if the rate of leakage will really increase or if it would be a nominal increase only.
Any suggestions as to what is going on ?
