Hi, I've got a Hatecke 7.5 FRB inboard with Voss jet. The tubes are getting pretty ripe. The hypalon has dry rot between the neoprene armor strips, impossible to fix from the outside. The tubes are bolted to the hull on the top and bottom with the bolts tapped into the internal aluminum frame.
Has anyone tried lining tubes with some type of inflatable bladder? I haven't checked with Hatecke in Germany to see if replacements are even available. They don't make FRBs and more, just lifeboats.
I'll post a picture when I can figure out how to do it
Thanks,
Mike
