I do not agree Rich. Those dory's I believe are actual representations of what the bluenose would have carried on board when heading to the Grand Banks. I would like to see where you have found evidence to the contrary. Check the 2:50 mark of this video and see what you think.

Some views later around 4;29 and shortly after that show some dories with the barrels etc and from my combined views I see probably only two maybe three seats not four as there is a lot of gear and the crew standing in the bow and stern areas. I'll send some drawings from the book
Bluenose II Saga of the Great Fishing Schooners, Nimbus Publishing, which shows the one thward with a hole for the mast forward and two seats on page 59. It is an excellent book with a lot of details (Bluenose II) and the references to build I (II)

from Bluenose.
Next more specific drawing of the gear and narrative

Next the more specific plan, elevation, sections, details of that fishing dory

Similar but with differences that you can use or not. The main problem that I have with the book which is all drawn and hand written text is that the writing is so small it is almost illegible for me to read even with a magnifying glass. Rich (PT-2)
