I’m building a boat with sails. But it tipped to the right. So I changed the weight and now it tips to the left. How do I balance it out perfectly. Like keep it stable.

Use props there the easiest because they go in the water and produce more speed while using less fuel and less air intakes.
Hope that helps

Go check out my boats if you need a reference
1 airplane fuselage, nose
2 use a vertical stabilizer
3 a jet engine

Just finished my first boat!

@AeroEngineering Ill disassemble your rig, hopefully i learn from it

@ElGatoVolador you Also want a stabilizing fin so it wont snap back to going straight after the turn. Try adding very heavy fuselage parts to the bottom of the stabilizing fin too.

Go disassemble my rib. Its a simple constriction that works well so you can learn from it

I use structural panels and rotators for steering.

Best way to make the boat turn is to make the propulsion turn and put some yaw under the boat I like props for propulsion but anything is ok you can make the hull with fuselage blocks but it is tricky and the boat might look more square than round.
