Dont put boyuancy on the red part put the boyuancy on the gray hull part to not make it sink

@ImZerkkZxe already tried and still sinks

Use fuselage block & increase buoyancy or use floating block in Gizmos part (but it may take more parts count)

@hpgbproductions man i never Thought of that
Usually i just increase the Bouyancy value to something really high that the ship can sometimes just fly if it touches water (hydrophobic)

• Buoyant force in the game depends on the mass of the part. If you add more dead weight, or increase massScale, a fuselage can float more. If massScale is 0, the fuselage will not provide any buoyant forces. This is the opposite of real life.
• Buoyant force applies from a single point. Each force is like a thin table leg. You need many to keep level.
