Lake Constance plays by its own rules: instead of the regular German Sportbootführerschein, you need the Bodenseeschifferpatent (BSP) to skipper a motorboat (category A) or sailing boat (category D) on the lake. The permit is examined and issued by the Schifffahrtsämter, the shipping authorities of the countries bordering the lake, and the theory exam draws on an official catalogue of 518 multiple-choice questions – asked in German.
This app contains all 518 official questions with the officially correct answers, plus the Hochrhein patent if you also want to cruise the High Rhine. Everything in the app is in German, and that is actually good news: you practise the exact wording you will face on exam day, so there are no surprises. A traffic-light system shows which questions still need work, explanations help you understand each answer, and exam mode grades mock exams on authentic exam sheets with the official time limit.
Photo tutorials walk you through every exam-relevant knot, and the whole app works offline. You can start for free with 100 questions – ideal if you are an English speaker living near the lake and want to see early on whether your German is up to the task.
Written for English speakers around Lake Constance – expats and internationals living on the German, Austrian or Swiss shore – who want to take a motorboat or sailing boat out on the lake. Since the theory exam is held in German, you need solid German reading skills; the app lets you find out early whether the official question wording is manageable for you, and then drills it until it is.
The Bodenseeschifferpatent is a standalone permit specific to Lake Constance and is examined and issued by the Schifffahrtsämter, the shipping authorities of the countries around the lake. The theory exam consists of multiple-choice questions drawn from the official catalogue of 518 questions and is conducted in German. The app mirrors this format with exam sheets in the official layout and the prescribed exam time.
The complete official question catalogue for the Bodenseeschifferpatent – covering motor (A), sailing (D), the A+D combination and the Hochrhein patent, with all signs and graphics, in German just like the exam.
Exam mode presents mock exams in the official sheet format with a countdown set to the official exam time. Each attempt is graded, so you know exactly when you are ready.
A smart algorithm rates your previous answers: red means keep practising, green means exam-ready. Detailed statistics show where you stand at any moment.
All 518 questions come with a clear explanation (in German), so you understand why an answer is correct instead of memorising letters – especially valuable when German is not your first language.
Step-by-step photo instructions guide you through every exam-relevant knot, each with an explanation and the knot's advantages and disadvantages.
No internet connection needed: study on the train, at the shore or out on the water without using any mobile data.
No. The app is in German only – and so is the official theory exam. All 518 questions appear in the app exactly as they are worded in the German catalogue, which means you prepare with the real exam language rather than a translation that would not help you on exam day.
Lake Constance has its own licensing regime: the German Sportbootführerschein does not apply here. To skipper a corresponding motorboat (category A) or sailing boat (category D) on the lake, you need the Bodenseeschifferpatent regardless of your nationality. The responsible Schifffahrtsamt can tell you which limits apply to your specific boat.
No, the theory exam for the Bodenseeschifferpatent is held in German. That makes studying with the original German questions the most effective preparation: on exam day you will recognise every question, even if German is not your first language.
Yes. The app contains all 518 official exam questions together with the officially correct answers, including all signs and graphics. Even the wrong answer options follow the style of the real exam, so your mock exams feel like the genuine thing.
Completely. The app runs 100% without an internet connection, so poor reception at the lake or on the train is never a problem, and studying uses no mobile data.
You start for free with 100 questions and can take your time trying the app out. After that, you unlock the full content – as a monthly or yearly plan or with a one-time purchase.
