Floatable boat/barge/drakkar/Viking ship

Hello ;)
I am currently working on a full Drakkar(Viking ship) model and this is my first prototype in which I wanted to test its floating capability. 
Floating works perfect so I decided to share this design with You guys ;)

This is just a first approach so it doesn't look like a drakkar yet :D but soon will be!
I am planning to:
-add shields to sides
-remodel bow, stern and sides to make it look more drakkar'ish
-add lockable compartments in a middle of a deck
-add mast 

I hope to add a better, more complete design soon. 
If You have any sugestions I would be grateful to hear them :)

Sooo, this model You can use as an inspiration or simply as a toy :)
Have fun!

Print hints:
I've added a splitted .stl file in which bow, stern and main deck can be printed at the same time. Just add supports as shown on a photo below!
