I believe IP uses 5200 to join the flanges, then installs a .25" bolt every six inches, then screws the teak
cap rail on with the screws extending through the joint, and the screws holding the stanchions go through the joint so you end up with a faster through the joint every couple of inches.
I believe putting the bolts through the joint here is a permanent fix, I'd be surprised if it is a problem in the field if the new boats haven't incorporated this fix in manufacturing.
I think hull to deck joint leaks
are not all that uncommon in monos too?
