The Mastiff's awesome cargo capacity and armament more than makes up for her lack of speed.
The Mastiff is a level 10 ship with one of the highest cargo capacities in the game, though despite its mercantile role, the Mastiff has a broadside not to be underestimated, and its size gives it a just as formidable health to withstand return attacks. However, the Mastiff lacks in protection along its bow and stern, an area of weakness particularly against chasing pirates or enemy bowlocks.
- The Mastiff, alongside the Pigeon, was added on April 21, 2021.
- On introduction, the Mastiff had the highest cargo capacity of any ship, with the previous highest being the now-removed Atlas holding 18 cargo. This title would later be taken by the Camel on June 25th, 2021.
- The Mastiff has a captain's quarters in the stern section of the ship.
- The Mastiff shares the same build requirements as the Astraeus, which was removed from the shipwright alongside the Atlas.
