Though rarely seen, the sand schooner is a popular vehicle among certain deep-desert denizens, who use it as a merchant vessel and as a warship. A sand schooner has enough room on its deck for two light catapults or ballistas. Because ships that travel on sand need not worry about sinking, a schooner’s cargo holds have additional hatches located on either side of the hull. These two doors are built to pivot downward and create a simple but effective cargo ramp. A sand schooner moves 2 to 7 miles per hour, depending on the wind, and requires flat, open sand on which to travel.
