Ship Stability Calculator

Calculate vessel stability, metacentric height, and hydrostatic properties.

Inputs

Ship Stability Formulas:
Metacentric Height (GM) = BM - KG
Righting Moment = Δ × GM × sin(θ)
Critical Stability: GM > 0.15 × Beam
Stable vessel requires GM > 0
Typical: 0.6-0.8 (container ship: 0.7, tanker: 0.8)

Results

Enter ship parameters to calculate stability characteristics.
