Ship just constantly swaying back and forth.

[Zierus]

So i just recently got back into this game, and literally any ship frame i build, doesnt matter what i do it just keeps swaying back and forth so much that its unbearable, its like a swing at this point.
Any help, what am i doing wrong? (the swaying just gets worse and worse when i put propellers on

If by swaying, you mean rolling and pitching, adding some well-placed propellers and general purpose PIDs can help. If you just mean being bobbed by waves in the designer is annoying, you can push CapsLock to freeze the constructable in place while in Build mode. Otherwise idk what you mean, maybe post video?

I can imagine something seriously misbalanced might behave so, check the force markers in Build mode and ensure your Buoy forces are showing up *at* or *above* your center of Mass.

Wide ships are quite stable, though slow. A lead or iron weight hanging off the bottom of the ship can also help. Hydrofoils at the waterline level and set to max will push the ship back straight when moving forward (my favourite method).

[patron saint of gaslighting]

you'll just have to build it bigger, mostly. and put most of the weight on the bottom.
