Keelwake keeps coastal and inland miles separate and counts only completed coastal cruises toward the SKS, the German coastal skipper license. You see at once what you've already achieved and what's still missing to reach your goal.
- Coastal miles automatically counted toward your goal
- Inland miles kept cleanly separate
- Miles can be confirmed by qualified crew

Practical questions
What a digital sailing logbook needs to do.
Keelwake supports documentation. The records required in a specific case still depend on the boat, cruising area and type of use.
What belongs in a digital sailing logbook?
A dependable entry combines date, route, positions, distance, conditions, engine and sailing hours, crew and notable events. Keelwake organizes these details by cruise and leg. The guide to logbook requirements for leisure craft explains the context.
Can Keelwake create an SKS mileage certificate?
Yes. Completed coastal cruises can be exported as a PDF with legs, totals and confirmations. The people involved remain responsible for accuracy and any required confirmation. See the SKS mileage-certificate guide for details.
Does the logbook work without a permanent internet connection?
The native app can be used locally without a mandatory account. The web app and optional sync between devices use a Keelwake account.
