Create your sea miles certificate in the app
SeaMemo turns your recorded legs into a finished sea miles certificate as a PDF, for German licences (SKS, SSS) and Austrian ones (FB2, FB3, FB4). Your skipper confirms the legs in the app and stores their signature once; you pick the legs and download the document.

How your certificate is created
- Track your legs. Every crew member can record with SeaMemo. Distance, duration, night passages and night arrivals are captured automatically.
- The skipper confirms. At the end of the trip the skipper confirms who was on board for which legs.
- Choose country and legs. Pick Germany or Austria and the legs to include. The app adds up the total.
- Download the PDF. The completed form with the skipper's signature is ready to print or submit.


Which forms SeaMemo fills in
| Country | Licence | What the app fills in |
|---|---|---|
| Germany | SKS, SSS | Several legs in one document, total, night miles, the skipper's certificate of competence |
| Austria | FB2, FB3, FB4 | Strict official form, one leg per document |
| Switzerland | Offshore licence | In preparation |

What the skipper stores once
So that the crew can download certificates, the skipper adds to their profile under personal data:
- their certificate details (name, date and place of birth, address, phone)
- for the German certificate their own licence, for example SSS or SHS
- their signature, drawn right on the phone
The trip itself needs the yacht details (type, name, flag, owner and dimensions) and the sailing area. The app asks for these when you create the trip, and saved boats can be reused. If anything is missing, the app shows you exactly what. Tap nudge skipper to send them a notification.
Why GPS data instead of handwriting
A handwritten certificate is quickly filled in and just as quickly questioned. In SeaMemo every mile comes from a recorded leg with start, destination, time and route. The app detects night passages itself. And because the skipper confirms the legs in the app, you don't have to chase them with a form weeks after the trip. Forgot to track a leg? You can add it afterwards or edit the route, see GPS tracking.
Cost
Tracking and logbook are free. To export sea miles certificates you unlock the feature once: no subscription, permanently for all current and future miles. The app shows the current price before you buy.

Frequently asked questions
Which licences is the certificate for?
For Germany the Sportküstenschifferschein (SKS) and Sportseeschifferschein (SSS), for Austria the FB2, FB3 and FB4 certificates of competence. Switzerland is in preparation. For other licences such as the RYA Yachtmaster, SeaMemo logs your miles but does not fill in a form.
What does the export cost?
The sea miles export is a one time unlock via the App Store or Google Play, not a subscription. After that you can export all current and future miles, on other devices too via restore purchases.
Does the skipper need SeaMemo?
Yes. The skipper confirms the legs in the app and stores their certificate details and signature once. If anything is missing, you can nudge them in the app or send them a link.
Why can I export only one leg per document for Austria?
Austria prescribes a strict form that allows only one leg per document. SeaMemo follows it, so you export each leg separately.
