About This Tool
The Hull Volume Calculator is an essential tool for naval architects, boat designers, and DIY boat builders. It accurately determines a boat's displacement, which is the total weight of water it pushes aside when floating. This single measurement is fundamental to understanding a vessel's carrying capacity, stability characteristics, draft, and overall performance on the water.

Key Concepts:

Displacement: Weight of water displaced = boat weight
Buoyancy: Upward force from displaced water
Block Coefficient: Hull fullness factor (0.3-0.6)
Stability: Resistance to heeling over
