Well the smaller sand skiff can't fit one on, hunter ships actually want tp get close to the Mohrans so using it for anything but to escape is counter productive, and Sand Pirates prefer to be able to sneak up on trade ships.

Most large ships do use them however because most captains prefer their ship in one piece and most traders prefer their goods to not be in the stomach of a giant sand dragon.
