Design Notes:
Structure is Medium, with Standard materials. Waterproofed. Armor is DR 3 Standard Wood. The volume of the craft was determined with the Builder's Old Measurement, where Ship Volume (cf) = [(Length - 0.6xBeam) x (Beam squared)]/188 x 35. A displacement value of 35 cf was used since the ship is open and would have very little freeboard. This value matches nicely to the value obtained by calculating the ship's volume as ½ of a spheroid. Empty weight is 13,155 lbs. There is an extra 122 cf of empty space; this could be pressed into an additional 2,400 lbs. of cargo capacity, or more ammo could be carried.
