If you glue the seams on a carvel planked hull, it is now longer a carvel
hull.. More like a stripped plank hull..

A carvel hull is built to allow the panks to expand and contract and for the
hull to twist with out opening a seam..

I have recaulked hulls that had been on the hard too long and the planking
was dry.. Being carefull not to drive the cotton too tight or it could cause
the plank to pull it's fastenings. Even if I only put in enough seam filler
to bring the seam flush with the planking surface, once the hull swelled the
excess filler would squeeze out 3/16" and would later have to be smoothed
down again.

If you want to glue the seams, select a strip planked design..
