Just a status update.
There turned out to be more damage than I had thought, accumulated over the years I guess. I discovered there were a couple of reinforcing tubes torn loose so I decided to pull the other deck too. That was a surprise because the bridle tang had been repaired previously but only up the hull-deck join. That means at the bridles angle of pull about half the bridle load was being taken up by a 2cm (less than an inch) stretch of tired old laminate! I didn't like the look of that so I ground it all out and re glassed that to the hull center line. Then about half way the deck, what had appeared to be a superficial gel-coat crack turned out to be a tear through the whole laminate! It was only the deck that was preventing the hull from folding like a paper cup. Really glad I found that... There were also no reinforcing tubes present in that hull, where the other hull had them and I could see how they would have been of help preventing that crack from becoming a tear. So I rolled my own and put them in too. Oh yeah, "co-incidentally" there was also a torn stringer in that area which I reinforced.
Then I glued everything back with straight epoxy because I had forgotten to get the micro balloons I needed as a thickener and didn't fancy another couple of hours drive to get some more. I used capillary action to let the seams take in more epoxy and they are rock solid now.
To top it all off I used gel coat, mostly because that is all I can afford right now. I cleaned and sanded the epoxy areas after a couple of days in the sun. Then I sanded with 120 grit everywhere I was going to re-coat in the hopes of the new gelcoat adhering (keeping thumbs crossed here!). The repair looks very decent considering this was not meant as a full restoration. The rolled-on gel coat hardened up with a nice decorative orange peel effect which I'm sure I will learn to love. Can't be bothered wet sanding and buffing that up but I'm told that would come out well if I did. I just want to go sailing asap!
The moral of this story is: If you have an old boat, like I do (1984, well at least the starboard hull, the rest could well be older!) and you get the chance to inspect the forward hulls; JUST DO IT!
