You have what I think of as "full length tubes". The early version of the
"tube" system runs the tubes from the chine to the hull liner. I saw this
arraignment on Larry Moon's boat and thought it made much more sense than
the way the tubes were installed in the later boats. In the #800s the tubes
run from the chine towards the liner but stop about 2" short. I am sure
that this was done to save money, not as a structural improvement. In the
old system it looked like each tube was cut to fit and glued in place. OTOH
the shorter tubes could be added to the hull before the liner was installed
which meant they didn't have to be hand fitted. Trouble with this system
is that it leaves a small gap between the liner and the end of the tube.
This gap acts a little like a hinge allowing all of the force, caused by the
hull sitting on the trailer bunk, to push on the end of the tubes causing
them to pop loose. When I re-glue mine I plan on extending, and gluing them
to the liner.
As to making it hard to store things in the cabinets, I glued (with calk) a
piece of plywood to the top of two of the tubes and then attached my water
tank to it. I plan on gluing down "floors" in both of the cabinets (after I
glue down the tubes) and actually like the idea of having these floors
raised off of the hull so the bilge water won't ruin what I put in the
cabinets.
