The Coastal Defense Ship was mainly used in the 1860's to 1920's. The design of this specific ship can best be described as pre-dreadnought battleship. Sweden and Finland used this design primarily although other countries did as well.
The Building Process
I started out by using red wool for the entire base.
I estimated how long I should make the ship based on dimensions I found.
After figuring out the length of the one side, I duplicated it on the other side.
After that was completed, I made two propellers on the back of the ship.
Next, I started with the next level which was black wool.
Next, I made the third level light grey wool.
Then, I made the deck with spruce wood planks.
After, I made the guardrails of the ship with the iron fence.
After that was done, I started building the second level of the ship.
After playing around with the height of the second level, I added the iron fence for a guard rail.
Next, I started adding two of the guns on the side of the ship.
I added the observatory and more detail to the second level of the ship.
I started then by adding the two navigating propellers onto the ship along with the smoke stack.
