I appreciate folks who take pictures of their models on cutting matts with scale grids.
Wiki lists her waterline length at 111'-11", and that looks to be 13"-14" about on your model. I get 1/8" = 1'-0" or 1/96 from that. Or maybe a little bigger, say 1/80 or so.
Then I looked at photos of the original ship. First, there are numerous patterns for planking big schooners. Bluenose looks to be the type where all of the planks are parallel to the fore-aft centerline. And using the trusty measuring tool of a sailors shoe, eight inches or so wide.
That sets your plank at around 3/32".
So now draw your centerline stem to stern. Some schooners like ones I've seen from the Grand Banks have quarterdeck planking at an angle that sort of follows the outboard profile and meets in the middle with long angles. It doesn't seem to be the case here.
Those bulwark supports or stanchions are really extensions of the ships frames. They also are at the ends of the deck beams. The deck beams of course are where the deck plank ends are located.
Youve installed what looks to be every third or fourth stanchion. The original had a LOT of them. It also looks as though they were evenly spaced. There are plenty of drawings of Bluenose from which you could get an accurate spacing, but why complicate life with this nice little kit.
You want to draw a series of lines perpendicular to the centerline, spaced evenly and at each frame/ deck beam.
Now pick a plank length that's a multiple of beams. These things could be pretty long, say 16 feet or so. More important though is to pick a length that matches a multiple of your deck beam spacing. A "Chopper" is helpful here.
The boatbuilder would have a rule like"8 by 4", for example. Every plank is eight beams long, every fourth plank has matching ends. They wouldn't be the obvious step sequence, but it might go with the second one beam up, the third two beams back the other way or some other regular pattern. Break the pattern where planks are between fore and aft deck houses and the space is less than a normal length; use a single plank.
Some stain their planks before installing them, I've never done that but I've only done a couple. There are a LOT of planks.
Then starting at the centerline glue down one plank with it's ends on your beam lines. If you can, add a few more in either direction until you come uo on your deckhouses, masts, or such. Now, start the next row by putting the next plank one beam offset from the first. Finish the row. Start the third row three beams back in the other direction from the first. What you want to do is be consistent with your steps to get a regular pattern, and not have one plank start at the midpoint of the one next to it.
Thats it. You're a little behind the eightball around the edges as there isn't an edge or waterway plank there, but slice them off with a razor blade to fit the curve of the hull and it'll look fine,
