In my thinking if you were to the leeward of an enemy you would be leaning over and pointing your guns higher giving more range to fire.
Whereas the enemy ship would be leaning towards you with guns dipped lower and less range. Possibly having to close the lower gun ports.
But what do I know it all seems a bit dangerous to me.

Answer B could have been correct if it had stated gun ports clear to windward, rather than smoke clearing, which was the killer part of that answer. Read all the answers firast before jumping in.

Not to mention the gun ports of the leeward vessel being above the waterline

That's true, Nick, but until everyone learns the problems of staying downwind in the days of galeons and vessels, the AI will never give up, hahahahah.
