let's build a ship

My suggestion of taking the ratio of flotation/weight and multiplying it by draught to get total hull height gives a height of 115 inches, and thus a freeboard of 71 inches, just under six feet.

With a height of about 9.5 feet and an effective volume of 4915 feet if the ship is treated as a simple block this gives a top surface of ~513 square feet, and with a beam/length ratio of 1:5 a beam of just over 10 feet and a length of ~50.6 feet.

Overall the ship's probably a little wider with that being the waterline beam, and a little longer due to not being a simple block.

And yes, this gives a deck area larger than that which the surface area and armour rules do - the latter assume each face of the vehicle is 1/6th of its area, which only applies to cubes, spheres, and a few other shapes and this ship is not one of them.
