Sanding, filleting, and saturating the inside of the hull

After finishing the inside of the deck we sanded and scraped the inside of the hull till it was smooth enough to not snag the fiberglass cloth when we spread it out. Then we filled all of the wire holes and parts of the seams that were still not filled with a small bit of epoxy and sanded those too. Then we put a small bead of regular epoxy down the stem seam.
We then mixed up a bunch of really thick epoxy and made a thick fillet down the inside of the stem seams.


At the stern stem a tongue depressor was squished up against the thick epoxy to hold it in so that later there will be a thick fill of epoxy that we can drill through to make hand toggles and a rudder.

I wanted to make sure that the fillets were nice and smooth before they dried because sanding down into the stems would be very difficult and the fiberglass is going to need to not get caught on any little protrusions.

Next we put three layers of fiberglass over the bow butt seams. One strip of 2" wide cloth, one 3" and one 4". The manual says to only do two layers (I think, it was a bit confusing) but when I watched the video that Pygmy has on youtube of the building of the Arctic Tern 14 (which has been very helpful) I noticed that they did three layers, so I did too.

Then we rolled on a layer of epoxy to saturate the inside of the hull to get it ready to fiberglass.
