I'm at 17 degrees N of the equater and have a ten year old Avon SeaRider. I'd like to say I always keep the boat covered and out of the sun but it just ain't so. My tubes are slack in the early morning and tight in the afternoon with the sun expanding the air. I don't have pressure release valves and don't have a gauge to measure bars of pressure in the tubes. What I do have is ten year old tubes that have seen more UV and heat in two weeks than a tube would see at 40 N. in a year and they are nothing if not perfect!
Properly constructed Hypalon tubes will provide a completely acceptable duty cycle in the tropics, period. Possibly you were too diligent in pumping your tubes or possibly you had a poorly glued joint. Hopefully you'll get some good advice on the re-glue job and not experience another blow-out.
