Costal driving license SKS is an Android app developed by Matthias Wimmer, available for free in the Education & Reference category. The app is designed to help people prepare for the written test of the Sportküstenschifferschein (SKS) license, which is required to operate a pleasure craft in coastal waters up to 12 nautical miles. The SKS license consists of three tests: a written test, a navigation test, and a practical test. This app focuses on preparing users for the written test and contains all the questions that may be asked in the exam. If you can answer all the questions in this app, you will pass the written test with flying colors. The app is easy to use and a great resource for anyone looking to obtain the SKS license.
