I had a little delamination on the inside, sides, of my ammas on my 1980 H16 last year and I did not repair it. I went ahead and bought the west system this year to repair it by injecting. However, when I checked again the area from the bow to about the front crossbeam most of it made a crunching sound when I pushed a little on it, also just below the lip where the top attaches. There are a few hairline cracks by the bow, and in a few other areas. The ammas have ports, which apparently were not sealed with epoxy and I believe this may have caused the problem. I fixed one last year by laying fiberglass and injecting resin between the layers at edge of the port- did not drill holes, but alas I did not repair the other hull, and now I need some help.
I have downloaded the Hobie delamination fix and the beachcats delamination repair. ( The difference I see in the two are the Hobie one says to make one large hole for injecting and several vent holes around the perimiter, while the beachcat method has several injection points and the use of 404 density filler, which the Hobie method does not mention.)
So I probably have a four foot section that has delaminated or is starting to delaminate.
Now for the questions:
1. Is it worth it to try the repair?
2. Is one method better than the other?
3. Can I do the injection with the amma still attached or do I need to detach it from the rest of the boat? The delamination is on the side of the amma.
4. Do I need to turn the amma on its side or can I just let the injected epoxy flow down between the fiberglass and foam when I inject it?
5. Should I use the syringes I have or should I get the caulk type tube?
6. Is the crunchy sound when I push total delamination or something else?
7. Should I use the 404 filler?
8. I have 1 quart of 105 epoxy resin and 7 oz of 206 slow hardner, do you think this is enough?
9. It was nice and dry when I was geting ready to do this project, but now it is raining, any idea how long after it quits raining to let the hull dry out from humidity?

The boat is not used for racing, occasionally flies a hull- did not get to sail last year- doesn't look that good this year either!
Thanks for the help.
