I have some delamination on the side of my hull on my 1980 H16. I went ahead and bought the west system this year to repair it by injecting with the west system syringes. When I checked the area from the bow to about the front crossbeam most of it made a crunching sound and was soft 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, delamination seems to be about about 4 feet long on the side of one hull.
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 hull still attached or do I need to detach it from the rest of the boat? The delamination is on the side of the hull.
4. Do I need to turn the hull on its side or can I leave it sitting on the trailer and 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 rained two days ago, any idea how long after it quits raining to let the hull dry out from humidity?
I have checked a bunch of posts, but they do not answer all my questions.
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!
Any help would be appreciated.
