Scenes from a plank

Planking is fun because all of a sudden, the boat's taking shape right there in front of you. What makes it tricky is that neither the plank nor the boat are flat ... and bent wood likes to spring back to being straight.

Here we have a few shots of getting Plank #2 on the starboard side ready to be glued. Each side has four planks, numbered up from the bottom, so this is the next-to-last plank on that side:

Here on the left side of the picture you can see the (loose-fit) plank curving away from the bow because I haven't clamped it in place. I'm testing the gain, which is a long, wedge-shaped cut on the plank below it to allow the overlap to become flush as the planks meet at the bow.

Same thing, different angle. Also note that our garage features a similar sort of lapstrake planking as the boat. 'Cept the boat is better made.

Plywood comes in 8-foot sheets; the boat is over seventeen feet long, so the planks need to be attached together with a scarf joint. In this shot, looking forward from the stern, the plank in question is clamped in place and you can see the vertical stripes where I cut the long angle. The aft-most piece of the plank, with a matching angle in its forward edge, will be joined here.

Next: the finished plank in position!
