About This Tool

The Center of Gravity (CG) Calculator helps you determine the balance point of your boat. A well-balanced boat is safer, more comfortable, and performs better.

Key Concepts:

Longitudinal CG: The fore-and-aft balance point of the boat.

Transverse CG: The side-to-side balance point of the boat.

Vertical CG: The vertical balance point of the boat. A lower VCG generally improves stability.
