Got it,
THANKS !

I wiggled in as far as I could in that 10x20 deck hatch cut out. I got a long handled brush and scrubbed everything with denatured alcohol after I vacuumed. I made fillets with wood flour and some chopped up glass mat. I also did the same on the good stringer on the starboard side.

That existing mat sure is heavy. It ate up some resin. Wish I would have filled it first since there was no grinding that I could really do .

I also reached up between the port side and the outside of that stringer with a length of aluminum foil. I rubbed it in for a template and then cut out a piece of plywood to fit, allowing room to glue in fillets top and bottom. I made a wacky brace to hopefully squeeze out the glue I troweled on after priming all sides with resin. It was mostly done by feel and hopefully not too much resin squeezed out since again I can't grind before glossing in

The flat 2x4 is holding the caved in gunwale to shape so I need to figure out something to retain that
Also after a long session of thinking about the way this all came to be I wondered why the corner of the fuel tank compartment did not rub through the hull after the stringer went. So I checked. It did. Hopefully it's not touching now but I can't cut and fill it without messing up this work. . . Cant I cut it out from the bottom since it needs a repair there anyway ?

I also picked up some nice old growth, 4/4, quarter-sawn, Douglas fir from a porch on a old farm house that I am redoing. It cleans up nice and has come in handy already.

I have to say this is addictive work

Thank you for fixing my pics, Marshall Moser !

I guess I will have to. Unless it's highly not recommended for some reason.
The hole in the hull is about as big as a pencil eraser. I can't get a pic because of the cradle the boat is on right now.
The boat will be flipped as soon as I get a handle on the topside.

That darn fuel tank compartment is probably still pretty close to touching the inside of the hull and remember the stringer was notched for it and there is no mat under the stringers so it only had to rub through 3/16 .

Once I turn it over how should I go about that repair ?

You can glass the fuel box to the hull bottom and it will become part of the structure.

Fixing the hole is another story. I would cut the box out, do all your stringer glassing and while you there glass over the hole with biaxial glass. Making a structural repair from the inside is MUCH easier than trying to do it fro mthe outside with only 3/16" of glass to work with. This make fixing the outside basically cosmetic (grind/sand out a little, then fill with a patch of woven cloth, then fair)

[Yhandy]

I see what you mean. That's what I will do. Thanks

[Yhandy]

That work has all been done.
I used Marinepoxy with fast hardener to repair the bottom. Daytime temps in the 70's . . 50's at nite

How long should I wait for the epoxy to cure before I can paint the bottom ?
Is the procedure to just rough it up, then clean and paint ?

A day or two is fine, the marinepoxy is 100% solids so there is no shrinking to worry about.

yes, give it a lite sanding (I would use somethign like 120-150 grit), then wipe down with your favorite solvent and rag

[Yhandy]

Ok, thanks.

I started sanding the entire hull early. ( watched the lunar eclipse through the back of the shop)
I pulled it outside, hit it with the leaf blower and scrubbed it down with soap and water. I rinsed it well, dried it and left it in the sunshine while I went to work.
When I got home I saw that I had received the answer that I hoped for so all I had left to do was pull it back inside, swab it down with denatured alcohol and get started.

It got up to 80 degrees today and the humidity was steadily dropping all afternoon so I was able to get 3 coats on.

The paint is Bluewater ablative. In my opinion it dries too fast but it seems to be good paint. It was gifted to me along with some Bluewater polyurethane high gloss topside paint and primer.

As soon as I can tape off the waterline I will start on the hull above that to the rub rail.
Prime, sand, clean. Repeat. . . Maybe again ? Roll and tip ?
I will do a refresher search on that step but is there anything that I need to do that I may not find ? Or anything special about this paint ?

I am hoping this next step goes as smoothly as the last so I can turn her back over this weekend.
