How to Use This Calculator
- Enter the waterline length, beam, and draft of the vessel in feet.
- Input the block coefficient (Cb) — typical values: 0.5-0.6 for cargo ships, 0.3-0.4 for fast hulls.
- Select water type (saltwater = 64 lb/ft³, freshwater = 62.4 lb/ft³).
- Review displacement in long tons and metric tons for loading and stability calculations.
- Compare the underwater volume in ft³ and m³ for buoyancy verification.
