I'm using 4 ounce glass on the inside.
My Petrel has been my primary boat for a long time. It has been through some serious abuse over the years. Not only has it been dragged up beaches and bumped into the occasional submerged log, I've also crushed in the side playing in rock gardens, I've stored it outside all summer in the sun with no cover, and kept it outside, uncovered all winter, I've also left it on the roof of my car while running errands around town. After all this abuse it was looking a little shabby.
I put together this 5 minute video to provide a broad overview of the strip-building process. My other videos go into a lot more detail, but if you want to see a quick synopsis of the whole project, this should help you out.
While many people mount these hip-braces or as I call them "cheek plates" so they extend from the deck and are attached to the hull at the bottom as well. I prefer to just have them attached to the deck. In this way I don't get a hard spot in the hull that might cause cracks as the boat flexes. I prefer to just cantilever them straight down and glass them in with a good fillet on each side.
You don't need to see more sanding, but that is what needs to happen before glassing the inside so I kept the sanding footage to a minimum in this video. Next I added a fillet in the chine. The Petrel has a hard chine aft of the cockpit, while it doesn't need a fillet adding one will strengthen the corner and make it easier to lay in the fabric.
I'm applying two different sort of fill coats in this video. One is quite light and the other is heavier. The hull will eventually get another layer of fiberglass, after I have joined the deck in place.
At the start of the day I went into the shop and turned the heat up to 80° F (27° C) and made sure the lamp I keep on my epoxy to keep it warm was turned on. This assures the epoxy flows easily.
I rolled the cloth out on the boat about an hour before I started glassing. I could have done it earlier, but I did want to give it some time to warm up to room temperature.
