News on the hybrid qajariaq:

I wanted one of those fancy recesses that you see 'molded in' on glass boats. I decided to attempt to lay up the recess and coaming lip all at once. I did it all in one monumental effort, yesterday.

I have some pictures up at http://www.frontiernet.net/~gdmurphy/greenland_coaming.htm but not much text. I'll fix up that page soon, it was very late, and I just wanted to upload the pictures.

The steps were:

Saw out the deck hole to the desired opening dimension, plus the layup thickness. Partially saw the desired recess dimension.

Determine the lip height. I used the top of the deck as a tool, except at the sides, where I built it up about 1/4". Mask with tape.

Build tool down on underside of deck. I used minicel foam as a tool here. Determine the height where the sprayskirt goes; I used 3/4 inches. Surform and sand tool to that thickness. Sand bevel at outside, running to deck underside. Soften all corners with sandpaper. Mask.

Lay up 5.8oz carbon twill / E-glass layers/ 5.8oz carbon twill. All was precut, on the bias. I used a combination of layers about 50 ounces thick.

Close the windows and let the attic go to 110 degrees.

When cured, cut out the partially sawed cut with a razor knife. The recess/coaming and the tool comes out as a unit. Sand off all the sharp edges so you don't cut yourself. Break out the cedar tooling, pull out all the foam and tape.

Mark, rout, and sand desired lip width. Same for the internal gluing flange.

Bevel the deck at the recess edge. Glue from the bottom.

That's all I did so far. I still want to fillet and tape the joint on the inside outside, and pretty it up.

This is not the best picture, but you can just make out the width of the lip where the camera flash is reflected. The lip underside is at deck level at the front and back, and raised 1/4 inch at the sides.
