This 1-ton object looks like a standard keel mount for a 10-ton ship. Originally designed for yachts, it has appeared in a few other 10-ton ships as well. A product of arcane magic, a gravitic stabilizer rotates a ship to automatically realign with the body of greater mass whenever the ship is subjected to the effects of another gravity plane. In other words, if a yacht is rammed by a hammership, the yacht rotates at the beginning of the next round so its orientation matches that of the hammership. This is a luxury item that delivers maximum comfort for the crew, thus its extraordinarily high cost.
The gravitic stabilizer can be used only on 10- ton ships matching, at least approximately, the keel size of a yacht. It cannot function on larger ships.
