Manta

The Manta is a Fleet Edition-exclusive ship and can be swapped to after the player upgrades to a level 2 ship at the Tonnsburg Engineering Guild.

Compared to the Beluga (the second biggest level 2 sub), the Manta is slower, less maneuverable and can be rather unwieldy in narrow spaces due to its length. Additionally, the Manta possesses 5 bolt cannons as opposed to the Beluga's 6, but this downside is negated by the fact that two of the Beluga's cannons are housed inside of a rear-facing turret (and thus can't aim forward due to being obstructed by the bridge), whereas all 5 of the Manta's bolt cannons can face forward at the same time, allowing the player to bring more guns to bear, assuming they are aiming straight forward.

The Manta's main advantages over the Beluga (and most of the subs in the game) come in the form of a cavernous cargo capacity of 40 units (compared to the Beluga's 14) and a similarly large crew capacity of 14 (compared to the Beluga's 10). This allows you to hoard a very large amount of loot before heading off to sell it, which can be useful when you get to the Sunken Coast as it does not seem to contain any Wandering Merchants, who are the only traders that will buy items at their full price. Thus, the Manta's large cargo capacity allows the route back to the Forgotten Fjords to be more lucrative should the player choose to continue selling their loot to Wandering Merchants after they make their way to the Sunken Coast.
