Hi all, just looking for any last suggestions before I sell off my 2001 5.5m Prestige cat hull rib (130hp) with great disappointment
The hypalon glue keeps coming away and one repair just leads to another burst. According to the local rib shop it's a known problem with the brand and I'm looking at a AU$14,000 replacement cost for the tube alone.
I paid $7000 for the thing and it was a lot of fun for a while, but then it started to lose air too fast for the on board compressors to keep up with. The internal baffles are all gone and the main leak is the front right corner join, and when I opened it up to reglue the seam I found all the internal seam layers look like they're pulling away. So a safe repair is unlikely to be an option. I think the fact that the previous owner sprayed it black just before selling it to me probably sped up the glue deterioration.
I've been trying to work out the cheapest possible way to keep the hull afloat out to my dive sites. The following are ideas I've had and in most cases found some evidence of being done before, but want more feedback on:
A) Foam-fill the old tubes (but takes on water and makes it heavy, hard to fill evenly, can crack).
B) stuff the tubes full of pool-noodles or beanbag beans (but beans are pricey and it still needs to hold air).
C) replace the tubes with inflatable fenders or boat rollers end-to-end (my top pick currently).
D) fabricate some aluminium tubing (but likely pricey).
E) keep it on the plane and hang floats around it to stop it sinking at rest.
F) glass up the sides so it's no longer an inflatable (or just transfer engine/jockey/steering/A-frame to a runabout).
G) join round plastic chemical drums end to end all around.
Obviously I have no interest in making it look nice, it just has to be cheap and unsinkable. If anyone has any solutions or experience with any of the options, please speak up!
