After landing a space plane into the ocean i have found ways of creating a space plane that floats. Use MK1 Structural Tanks as floating devices I want to see who can get a boat to ride the farthest,fastest, and also looks somewhat good. Recommendations: The boat should be back heavy(because with my design the engine pushed it into the water) multiple layers of structural tanks without decouplers between them(they dont like water) So do u think you can make the best?
