I don't have any data to give you. But, consider that most of any force that gets applied to the panel will concentrate at the chine joint. Anything you do to stiffen up the panels will serve to increase this stress concentration at the joint.
From a strength standpoint, I would rather tape the joints and forego the glass on the panel than the other way around.
If I were going for super-light I might consider not putting any glass on the inside, neither the joint or the panel. But I would still put some glass over the outside of the joint.

: ok,,I should know this but looking for thoughts. For a four panel hull is
: there any reason to use tape if the panels are glassed on both sides with
: 6oz cloth? I'm thinking about pre-glassing panels with 4oz on the inside
: and just curious about the absolute necessity for a particular
: construction. At what angle of side/bottom panel (load irrelevent) can a
: fillet suffice and when does glass have to bridge over the fillet? For
: deck/hull joined with tape on the interior is 6oz cloth sufficient
: compared to 9oz tape?
