The theory will be the same...

But, that much delamination will be hard to cure. It is quite possible that there is a large separation between the layers on the sides and that is more difficult to get a good repair. The repair only bonds the original layers together and in most situations there is very little space between the layers. If the sides are bowed, the repair method it'self can not correct it.

Delamination is a huge structural issue, which can cause sudden failures when under sailing loads. Understand that this can leave you stranded on the water. I would be very careful with a boat with any delamination. I wouldn't be sailing on open seas with a boat like that.

I'm inclined to agree with Matt. If you have soft spots in the sides of the hull, then you've lost a great deal of strength there. I'm willing to bet the hull is less than 50% of its intended stiffness and could easily break in half.
I definately would excersize extreme caution sailing the boat in this condition.

You might consider a major repair which would probably result in the hull being stronger-than-new if you're up for it. We performed this on my friend's Sunfish with a big crack in the keel.

1) Remove the soft spot so you have a large hole in the hull
2) Get a piece of oak board and cut / sand so that it fits inside the hull with contours to ensure maximum contact
3) smear flox/epoxy on inside of hull and oak board
4) Insert epoxy-slathered oak board into hull and pull tight
5) Allow to cure
6) Fiberglass over remaining hole
7) Repaint hull

See part three on my Sunfish page for images and more narration:

Good luck!
