About Boat Buoyancy

Archimedes' Principle:

• Buoyant force = Weight of displaced water
• Boat floats when buoyant force > weight
• Draft increases with weight
• Freeboard is critical for safety

Stability Factors:

• Metacentric height affects roll stability
• Beam-to-length ratio impacts stability
• Center of gravity should be low
• Weight distribution affects trim
