I agree that tacking is too hard. I was thinking maybe a sloped + to skills based on size. Something like +1 for medium and +2 for smaller than that. Brigs should be able to tack pretty easily. But I agree that it would be harder for a first rate to in a combat situation.
I have seen no clear indication either way. I was a little disappointed in this one, particularly as the named ships that backplates and figureheads are provided for have differing numbers of guns and could be represented by the different sizes.
I think we’ll have to wait and see.
I can answer the first question. How often you move and turn depends on sail level:
Light Sails – Move, turn
Battle Sails – Move, turn, move, turn
Full Sails – Move, turn, move, turn, move
No last turn at Full Sails
I guess I’m not saying that it should be risky, but the combination of rules make it nearly impossible.
Literally impossible for anything will a yellow turn.
Feels like a +1 or +2 modifier to the skill test for this would be more representative of history, maybe depending on ship size.
