Version 1 is complete!
Ship has 7 hardpoints, but no weapons are fitted. This is mostly because I focused so much on the core design, I didn't think about where the turrets would go.
The cargo is a double deck zone, and when the ship is in water, can be flooded to allow cargo to float into the bay. Perhaps in a later iteration of the model, I can model the doors in properly along with some popup turrets.
Enjoy.
