Zunder had that somewhere, but I think it is close to 120. But with the ever full sails, and an elite crew, 120 is not necessary.
A normal compliment would be ~100. Historically they didn't have prelates/mages etc. so i believe 120 is right.
With more modern mechanics, you can sail her infinitum with around ~80.
Normal compliment of gunners would be 5 per gun, with the breach loaders on the Guardian you only need 3. You generally use regular crew for the grunt work, and one gunner per. So 2 able seamen, 1 gunner. Only need 27 for that ( only usually fire one side at a time, so 9 active weapons) - 1 Gunner, 1 Powder Monkey/Loader, 1 Gunners Mate
STEPS
- Boom
- Loader Opens the Breach
- Mate cleans the bore with a giant q-tip
- Loader Loads the Weapon, and Locks the breach
- Mate helps Aim the weapon
- Loader goes to the powder room waiting for the guns to fire for next pouch of powder.
- Boom
The breach loaders remove the responsibility of rolling the fun back and forth to aim and load ( usually done from the front of the weapon)
That further reduces the crew
The sails make it even less, as no rigging changes, not much taking.
I figure you can sail her forever with a crew of around 65.... But what fun is that.
