Here is how I repaired the hulls on the side of my h16. The boat was on the trailer and not on its side. I had the ripples on the side, the delamination repair did not remove them, but they seem to have no effect on the sailing of the boat. I used the west system, if you use it make sure to get extra of everything you need, (Epoxy, hardner, syrenges etc.) You can always returned the unopened containers for a refund. I repaired it last fall and sailed this summer with no problems. A tip on using the syrenges- after you put them in the hole you drilled you may have to back them out just a little to help the epoxy flow, I also cut the tips of mine at a slight angle. Also cover the entire area plus the bottom of the hulls with a good quality 3inch masking tape, this will help clean up and keep from getting drips of epoxy on your hull. I drilled a lot of holes in the side of the hulls using a 1/8 inch drill bit with a stop set at about 1/16 of an inch- you may need a little more depth, but do not drill through the inner hull.
