After selecting a vessel, open Home and review the operational overview; a Home card is navigation and context, not a newly calculated result.

Not a loose collection of calculators. CaptainCalc keeps vessel, voyage, source and record context visible from input to export.

Open Records from the recent-work area and confirm saved timestamps and source details; resolve missing setup instead of inferring a result from a summary.
CaptainCalc is decision support. It never replaces approved stability data, loading computers, ECDIS, official publications, procedures or professional judgment.
Freemium keeps essential online tools available with ads. Premium removes ads, raises limits and unlocks the complete offline professional workspace.
