My boat no matter what I do either bounces up and down in water or becomes a beyblade no matter what I set the values at.
Pontoon settings.
Buoyancy Settings.
Rowboat Settings.
Collision is blockall.
This is the results of the values that I have.
Hi welcome to community,
Just lower coefficient to a small number, and you can also lower damp. Lower your max BouyantForce also to a very low value like 100.000 or even lower.
Increase your Angular damping and you should be fine.
