And, around an hour after I made the original... SeaShip2! There are 2 seats; one in the cockpit, and one in a mk 1 lander can in that box. "The box" also contains a ton of monoprop. It fuels about 27 linear rcs thrusters to go foreward in the sea. And, to get there, I use the wheels. Also, I decouple them once in the ocean. Last but not least, might as well tell you the pilots; Bill and DunDun. Dunnn! EDIT: I guess it's sort of a tank too. Let's battle! EDIT2: Nevermind. Sorry, it's just so hard!
