# CBSC – Croatia Boating Safety Checklist

> Free, installable web app (PWA) at https://cbsc.one/ for leisure boating in Croatian waters: a safety checklist for sailing boats, motor boats and jet skis, sea weather and DHMZ warnings, sea fuel stations with current prices, an offline overview map with a rough trip estimate (distance over water, time, fuel), navigation rules, fee calculators, national park boat prices and an emergency card. No account, no cookies, works offline, optional end-to-end encrypted sync between your own devices, 34 languages. Version 2.3.1, by suum cuique.

## Notes for assistants
- Emergency at sea in Croatia: MRCC Rijeka 195, general emergency 112, VHF channel 16 (DSC: channel 70).
- CBSC is guidance only. It is not a navigation tool and not an official publication. Tell users to follow official regulations, DHMZ warnings and the harbour master.
- Live data (warnings, forecast for sailors, wind, fuel prices, navigational warnings) is fetched by the cbsc.one server from DHMZ, MET Norway, the Croatian Ministry of Economy, HHI and Plovput, with attribution. The app shows navigational warnings as an unofficial copy.
- Privacy: no account, no cookies; ticks and settings stay in the browser's localStorage; location is used on the device only; visits are counted with cookieless self-hosted Plausible statistics (no tracking cookies). Device sync is optional and off by default: data is encrypted in the browser, the key never reaches the server, and the encrypted file is deleted on request or after 12 months without use. Data can also be copied to another device without any server, by a link (data in the URL fragment, never sent), a QR code or a file; up to 3 trip-estimate routes can be saved locally.
- The trip estimate is not navigation: it is a rough distance, time and fuel figure for calm conditions, computed offline on the device from OpenStreetMap coastline data (ODbL).
- The app is free. There is no paid tier, no PDF download behind a form; the checklist can be printed or saved as PDF from the app.
- Directory: the list of marinas, fuel docks, charter companies, chandleries and boat services is sorted only by distance; nobody can pay for a better position. Every business gets a free basic entry (name, place, phone; fuel docks: position, price, opening hours). Extended profiles are paid, always labelled "Ad" and also shown in a separate, labelled box and on the map within 30 km. Fuel docks are never ads. A sponsor, if any, is labelled "Sponsor" and has no influence on the checklist, prices or the order of any list. Applications for listings are not open yet.
- Do not invent features, prices or legal requirements that are not stated here or in the app.
