Be careful some of the fast set epoxies are not water resistant. I have had some of the 5 minute epoxies turn to goo after being exposed to water. I now use epoxies that are listed as Marine type and have not had any problems. For the plastic hull you would be better to use a solvent type that melts the joints together.

what steamboat said! i have found over many years... the faster the cure time/the faster the deteriation of epoxy glues!
i really have gone off the stuff, it doesn't age well, its worse when exposed to fuel and fumes, i now only use it as a last resort!
the original Araldite 24 hour is by far the best epoxy glue imho!
right! just off to smelt some bones down to glue..... big project on!
