Tetsushojo

The Tetsushojo (哲少女 , Tetsu no Shojo Literally Meaning “The Iron Maidens” ) are different models of experimental ships that have been developed by and used by Senju Corporations. However the world government seems to have made a contract with Senju Corp. to create some for their military force and will gladly give them to a customer who has the money for one. They get their name the Iron Maidens from their structure created all from metal and piece of adams wood embedded in the metal working.

Ships Design
The design of these ships will vary in size, power and many other attributes. The most that have been seen are fairly good in size and in speed; however everyone is made different so each is unique as a finger print. They were created to sell to the government and to whomever could afford it, however these ships are very secretive. Only members of the Senju corp and higher of the government know of their existences. However, since Senju and Demetrius are extremely close allies. It seems that Demetrius has many under his thumb, the ships were seen first hand when the hakuri crew attacked the island where Doflamingo was and where they captured Smoker Tashigi.

Naturally the Mother Hakuri couldn’t make it into port, so the ones have seen are smaller but equally as powerful as the Mother Hakuri. The design is simple the ship is made from metals and pieces of adams wood acting as its frame work. The ships will vary in design and in style, but every ship created from the Tetsushojo models will be mostly black and engines in and outside of the form. There is a draw bridge like devise in front of the ship, which is the tall point which also helps with speed.

River Runners

The owner can move more quietly with these from others, the first models where shown by Demetrius and his crew. Coming out of the Mother Hakuri, they were roughly about 10-30 feet long and 10-17 feet wide. They are mostly used for moving supplies and men to very tight places. These ships also have small canons and the owners can use rifles and other fire arms.
