Thanks Chris. For the inside curve, I used the plan view of the boat where there are measurements from the edge of boat, to the inside curve. There is a dimension given about every foot from edge of boat to inside of curve, i.e. 7 1/2", 7 1/2", 7 3/4", 6 3/4" and then 11" from the very front of the boat. I just plotted those points on the cover board (I had already faired the outside of the coverboard to the shape of the hull) took an 8 ft length x 4" of 1/4" plywood and bent it to line up with each of the points. As I held the plywood, my wife quickly traced the curve onto the coverboard. I then was able to remove the coverboards and cut it on the bandsaw and/or jigsaw. It seemed to work pretty well.

I agree with using the less agressive sander as soon as you can. I used the belt sander only on the edges of the cover boards to knock them to within 1/8"~1/16". I then used a 1/4 sheet palm sander to remove the last bit and shape the coverboard to the same profile as the hull. At this point, it might be back to the tool shelf for the belt sander. I think all the main fairing is complete so I shouldn't need it anymore.

Today, I cut and installed the kingboard. Pretty straightforward. I used carbon paper in order to transfer the interior curve of the coverboard onto the underside of the kingboard (laid the paper over the coverboard, set the kingboard on the carbon paper, and hit down on the kingboard with the palm of my hand). Used the jigsaw to cut across the carbon line and a little sanding later it fit pretty well.

Finished the kingboard and then stained the coverboards and the kingboard. Also finished the front seat bottom and back. I hope to start the deck boards soon. I am thinking 2 1/4" width with 1/4" white caulk joints. Any thoughts?

Look's Great!! 2 1/4" sounds good. I did 2 3/4" and it came out nice. The size varies among boats and you need to do what pleases you.

Yes, lay it all out first to make sure you dont have too skinny a board on the outer edges. Then you can alter the width if needed. The stain looks great.

Thanks guys. Good advice. I switched to 2 3/4" in order to avoid having a very skinny last board.

Spent some time today cutting and planing the deck boards. Tomorrow I may be able to start installing some of them.

I laid mine out starting in the middle by the king plank. That way any skinny board would also be short ones out at the edge. You can look back at my build to see how my cover boards came out. I used 2 3/4" with 1/4" caulk lines.

Thanks....always good to have references! I spent a little time this weekend installing the deck boards. I made it almost half way through. It went really easy. I used carbon paper to transfer the coverboard shape to the underside of the deck boards. Essentially, place the carbon paper over the coverboard, set the deck board in place, and then tap firmly, but not hard, with a mallet. Simply cut the shape with a jigsaw, some light sanding, and the board is ready for install. However, I only wanted to install one row at a time since I am not using any screws on the deck. I installed a row and then waited for the epoxy to cure (mostly) before I began the next row. By doing this, I could keep all the rows exactly where I want them. I will have seven and a half rows so it should take less than a week doing it this way. I was able to apply 2 rows each day on Sunday and Today giving some time for the epoxy to cure. I might be able to do one row each evening this week to complete it.

Looks awesome! I'm very jealous--my boat was framed when you started and I have yet to flip! :lol:

Andy - you'll be flipped in no time. No worries!

I finished installing and sanding the strips on the deck. I am going to dust off the surface and encapsulate it. I am then going to lightly sand the deck boards, kingboard and coverboards. The one more coat of clear epoxy. After that, I am going to use white pigmented/thickened epoxy and "caulk" the deck lines. The clear epoxy will keep the white pigmented epoxy from spilling out of the joint lines and penetrating the wood. I should be able to sand off any white epoxy that spills out. I've got a very busy week ahead (not boat building) so not sure how much I will actually get done on the boat.

Looks great! Having seen some colored epoxy this week, it seems like a great way to go.
