Hi Neptune.
You have highlighted my point exactly. Investigator (Fram) was a collier, similar to Endeavour, Bounty and Adventure. She started as Fram with quarter badges as documented and was documented as having quarter badges after being sold off. If that watercolor is the only reason for having galleries its pretty flimsy evidence. Bob Sexton argued that it was to provide the officers with a latrine. Well why didn't the navy do that on the other collies?. When Bligh lost his cabin to the breadfruit they provided him with a latrine on the quarter deck abaft the rudder post. Oh no wait that's a flag locker, someone else has settled that science. Even though on Providence the second breadfruit ship has similar "2 hole" latrine in the same location.
The point being is that the science is never settled and it is valid to test previous interpretations. I will post a couple of pics soon.
Regards
Allan.
