I do believe you are dead-on!! If you read the postings when the boat was for sale, one person notes that the boat was once yellow. If you look at the building blog, you will see a yellow boat in the final picture.

A very interesting design - especially the bow /stern treatment!!

As mentioned, somewhat BP-ish but it has an extra chine!!

I wasn't sure it was the exact same boat until I read the postings and spotted the yellow reference. Is there yellow showing through scratches here and there? Some Haida influence surely in the stems, and the bottom looks like a perfect match given the arrangement of the stringers in the build blog. Construction has gone almost the full circle, from the SOF of the original that inspired the strip-built BP and then the ply over frame version shown here. The only one missing seems to be S&G.
