Forget 30 years, I wish I could get any set of tubes to last 10 years....
My R.I.B.s work in pretty heinous conditions, i.e., landing against ship hulls, against rocks, landing on barnacle covered structures and god knows what else, and I can trash a set of Hypalon tubes in the span of three years. The Wing polyurethane tubes last on the order of triple what a Hypalon tube lasts...
And unlike my experiences with hypalon, I've never had a fatal blowout or huge tear in a Wing polyurethane tube. I've come home from jobs with half a hypalon tube hanging from a boat like tattered drapes...
The other HUGE plus is the strength of the attachment points; I recently had my 36' R.I.B. stuff the bow into a 6' wave and the hypalon tube separated from it's bolt rope attachment at the bow and down both sides about 8 feet. I've stuffed Wing tubes into larger seas and at greater speeds than this and never had an issue.
My primary concerns are safety and durability and having the boats make it home in one piece after a tough day, hypalon doesn't come close to a Wing tube in this regard.
