Sure thing....
Did you plan on using a construction system? Or are you going to use historical designs only? There were a lot of innovations during the latter half of the 18th century... one of the biggest innovations of the time was the Frigates of the fledgling US... such as the USS Constitution. The Hull, rib structure, and keel design were radically different than the norm for the time, resulting in a faster, more durable design. The designer of those ships actually snuck out of England after he had attempted to sell the idea to the English, and they refused.
Also, there is the Razee's.... Which were British ships of the line that the French captured... they would raze (remove) one of the decks, and make it a lower sleeker design.... faster and more maneuverable at the cost of some firepower.
The reason I bring this up is that the American Frigates were vastly superior, and could stand up to ships with half again as many cannon, and frequently gave British ships of the line a run for their money...but were definitely within the same time period. French ships tended to have better rigging and sails, and were maneuverable to a fault... which makes me wonder what would have happened if we could have gotten an American hull, French rigging, and British crews and gunnery, all on one ship......
