Bunks!??? The wimps!
Seriously, tho, bunks, while comfy, are rubbish in a storm - even a deep swell means you just fall out. Hammocks are really the de rigeur "thing" for your tough old sea dog! Also saves space for cargo.
Apparently Columbus's crews slept on deck there was so much cargo. Crew numbers surprised me initially but is actually about right after a quick check around.I imagine you've been using figures based on Columbus who had 2 Caravels and a Carrack I think?
Anyway, it looks great!
