Thank you. I have indeed scrolled to that and it is the file that downloaded without telling me it was or had so.
In the index page 200 mentions collapsible bulwark
s and this is found actually on page 212 in the pdf. it seems to refer to lifeboat
s and albeit a few pages several are blocked from view as are some of the drawings
. I believe it said one has to be a member in order to see those pages.
I don't think that the information concerns the ship's bulwark
but rather the side of a ship's lifeboat
What was it that you read?
Am I yet in the wrong link.
