I’ll give it a stab….I’m thinking cost …. I would guess the aluminum goes together much much faster vs cure times, fabrication molds etc. What about weight ….I’m not sure about that ….how many layers do you need to make the tank safe ??? Then glassing in vents , fills, uptakes, fill gauge ….. Glassing in the baffle system ….. Good question about CG regs….they must have some sort of standard or hypothetical “lay up” schedule to attain the proper thickness.

Of course corrosion isn’t a problem …

The boats I used to “play” on had Fiberglass tanks …. They had some issues …but only because of age and the inability to remove them and clean them
I think I'll stick with aluminum ... epoxy coated [img]/images/graemlins/smirk.gif[/img]
