The Spanish Armada ship named El Mono (The Monkey) uses a customised brown and blue narrow hull with two middle sections.
The hatch at the front is used by the crew to access the lower deck. Notice the ladder inside:
Those sections are removable for easy access to the interior areas of the ship:
This is the lower deck, with four beds for the crew, also notice another room at the back with the treasure chest - unfortunately this area cannot be accessed, so consider this to be a secret treasury if you will... :)
Not much room for a captain's cabin on a ship this size, but it's just enough for a bed and a small table with a map, and of course - some booze:
