Let's end this once and for all until a new update changes things. From what I gathered the sloop is the fastest into headwind with sails in the middle. For the other two ships sails should be to the side during headwind and not in the middle.
Lastly is tacking a faster? You're trying to get from point A to point B during headwind. If you start tacking will you arrive faster? Assuming your crew is perfect.
