Raking.
Isn't it a bit of going back to square one to buff raking? If I remember it correctly, it was nerfed since yachts had no problems with 1st rates... ( yes this is where my pessimistic eyes and thoughts got stuck for a while please forgive me)
Crew focus
If I got it correct this will enable us to, for example, sacrifice a percentage of sail management to repair leaks at the same time? If so - Great!
Im not sure if I like the idea around the crew for cannons thingy however.
Mast magic
Meh.
Production buildings
This is where things can get real interesting. I've always been a spokesperson for a total playerbased economy.
No resources should be automagically produced at ports.
And why not have so that some ports will give a bonus output in some production buildings.
For example. Philipsburg gives a bonus output to wood. Or if more specific, Philipsburg gives a bonus output to fir log. Guayama gives bonus output to stone. Etc.
That would make planning port conquests more important as a sort of side effect.
New ships
More ships are welcome! We need ranks also. Ranks are good. The gap between frigate/belle -> 3rd rate is where the constitution sits without love.
