That's all true Hans, but the assumption is the stepping can be performed
with access on both sides of the repair. That isn't possible in many cases
after the new tanks are installed. Possible, yes, probable, maybe....

I, like many others, cringe at the idea of cutting open the boat to get the
tank out and I would not do it in ours. BUT, it is possible to get the same
strength or even better at the reglassing. I listee used the phrase
scarfing.
We call it stepping. The sides are stepped at an eighth of an inch or so,
and
make a "shelf" that way. Do that untill the cut looks like an asian mountain
ricefield with the terracces. Lay one up at a time and when finished, the
whole thing gets vacu-bagged and autoclaved. You will now have a superstrong
repair. That's the way repairs are made to composite surfaces on airplanes
you
ride in over great distances, and I have yet to see a repair go bad.
