Um for the drifting thing my boats do that too but sometimes if the VTOL turner is in the front of the boat instead of the back it helps@AeroEngineering

@NachoMan I never thought of useng a swinging counter weight to keep a boat from rolling. Thats just Genius. but I am askijng because I am building a motor lifeboat and trying to keep it to the specs of the real ones. I just solved the roll problem but she loves to drift and has a bad turning radius so I am trying to find the solution to those.

U can put xtra weights at the bottom of the boat, have the turning thing (VTOL or propellers or whatever) in the horizontal line of mass thing so it doesn't push on the top or bottom too much, or use a counterweight that rotates to put the weight on the side of the boat that would begin to roll
