As for Pelican durability, actually, the model I started with, is
still going strong, bought it in what, 04, 05 or 6? My 4 sons have
beat the crap out of it (so-to-speak) in fresh and salt, dragging
to and from docks, etc. Actually, I've instilled in them to take
care of the gear so it'll last. Point being, it's been used hard and
often and is leak/crack free up to now.
From the looks of the drive area in this new one, it appears to
be reinforced with a separate molded housing. But yeah, time
will tell its durability. I know some Hobies have had issue in
the Mirage Drive area with cracking...but they seem to be on
that and taking care of issues reported.
As Hobie's patents expire, others will join the fray if it's easier
to wait and let Hobie front the engineering builds/expenditure.
I imagine Hobie has several patents on 180 varieties, though I
have not done the searching in the patent dbs on the matter.
