Use case

Check initial stability before committing to a load plan.

Quick GM estimate from principal dimensions and center-of-gravity input.

Trusted inputs

Initial stability box-barge approximation

Range notes

Supports metric metres/tonnes and imperial feet/short tons.

Rectangular hull approximation only.

Water density can be set to seawater, freshwater, or a custom site value.

Important

Engineering estimate only. Use full naval architecture analysis for final decisions.
