Am-MulardA - A steam ship 115 feet by 23 feet large that carries three fixed guns to the front of the ship, one on each side and one forwards. Its power comes not from sails, but from a steam engine specially designed for it that uses a network of pistons, gears, and a flywheel to provide force to the twin paddle wheels. The engine winds up failing from time to time due to the many cuts to bring it to the minimum required to not have it be too heavy to sink the boat. The wood frame is light and as a result can be sunk fairly easily. The paddles and required shape causes it to perform poorly with even minor waves, so it needs to stick to rivers and the inland lake. (National Effort)
Problems:
Armor was scrapped after its addition nearly sunk the boat.
Screw Propellers would not provide enough force to be able to push the boat.
Tech Gained:
Paddle Wheel Boat [Expensive]
Steam Engine [Expensive]
You reached a bit far with your design. Even without your rolls being a bit on the bad side, the fact screw propellers weren't used on a ship til 1824 (44 years from now), and at this point the only ship that had a steam engine put on it wound up sinking gave you a couple penalties. Not so much with the engine as one does crop up in 3 years in France that works...though it failed after 15 minutes. Well look at it this way, you have something to put on the inland lake. Anyway...
You have now entered the Revision Phase.You may revise any piece of technology you have, to a reasonable degree. For example, you cannot turn the Brown Bess into an Air Rifle, but you can upscale the shot to make a higher caliber musket.
