These are the structural questions about my "Super Dreadnought".

1. How wide would the ship have to be to be stable on the water?
2. Would the Caterpillar treads hold the weight of the ship?
3. What would be the approximate weight of the ship (without crew and ammunition).
4. What would the water displacement of the ship be?
