There have been several previous threads chronicaling the construction of my 25' Hooper Island draketail. At the end of the last thread, construction had reached the stage of the keel, molds, frames, shear strakes, chines, and draketail stern all ready to accept planking. Details can be found in the following threads:
Here is a picture of where things stood at the end of the last thread.
The draketail is a hard chined Chesapeake Bay work boat with horizontal side planks and a cross planked bottom. Some original boats had side planks as wide as 22". I don't have that luxury, but do have some nice 11" Douglas fir stock for the side planks.
I would appreciate some advice on lining off the sides for the planks. I've made an attempt at it based on the following thoughts:
The plank stock is 3/4" x 11" x 22', recycled Douglas fir.
At the stern, the width to be planked is about 18".
At the bow, the planking totals about 36".
Our thoughts are to use as much of a full width plank as we can get away with at the chine. If we leave the "shear" edge of the plank straight, it goes from about 10 1/2" at the bow to 8" or so amidships, back to 10 1/2" at the stern. The width puts the first side seam about 4" above the waterline. At normal loads, there will no side seams under water.
The second plank (the one above the chine plank) would start at about 8" wide at the stern (station 20') run out of it's 11" width at about station 11'. At station 11', we'd start the first stealer plank by nibbing in a 4" end for the first stealer. (would 3" work?) Stealer # 1 and chine + 1 would then both swell back to about 9" at the bow.
Then, Stealer # 2 would start at station 4 1/2', nibbed about 4" into stealer # 1, and again swell to about 9" at the bow.
As best I can tell, this arrangement makes the best use of the available stock. I assume that's the way the old folks would have approached the problem. Will this approach work? Have I crossed any horrible aesthetic boundaries in the process of lining off?
Here's a picture of a plank roughly in position of the second plank. (minus the stealer) The lower edge of the plywood spiling batten on top defines the shear (upper) edge of my proposed first plank.
And here's a rough sketch of the proposed plank layout:
