Your digital companion on Lake Chiemsee, Lake Starnberg, the Ammersee, the Tegernsee and the Brombachsee – made by sailors for real life on the water. Whether trip planning, navigation, anchoring or weather: everything for a safe, relaxed day's sailing.
Lake Chiemsee, Lake Starnberg, the Ammersee, the Tegernsee and the Brombachsee – you pick your lake in the app and everything follows suit: its own map, its own harbours and jetties, its own zones, gauge, weather and webcams. Your trips stay neatly separated by cruising ground.
The “Bavarian Sea” with its two islands: harbours, steamer piers, storm-warning lights, quiet zones, the three anchor zones for overnight stays and the Chiemsee Championship regatta calendar.
The long lake outside Munich: sailing clubs, boatyards and marinas, slipways and cranes, steamer piers, storm-warning lights and the protection zones along the shores.
The broad lake west of Munich: harbours and jetties, shoals, slipways and cranes, steamer piers and protection zones – with its own chart, its own gauge and its own weather.
The alpine lake in the south: sailing clubs, the ten steamer piers of the lake shipping line, storm-warning lights and worthwhile spots along the shore. Motor boats are banned here – you sail without engine noise.
The Franconian Lake District: harbours, slipways and cranes, steamer piers and the two nature reserves that are closed all year round. Being a reservoir, its level swings widely over the year – the app shows it updated daily.
This is not a picture but the real map from Binnen Skipper: the same tiles, the same harbours, piers, storm-warning lights and protection zones. Zoom in, tap a symbol or switch to full screen.
Binnen Skipper is an orientation aid and does not replace an official nautical chart. Information on depths, shoals and harbours may be incomplete or inaccurate; official documents and your own assessment on site remain authoritative.
In the app this chart lives entirely on your device – it works without reception, with your position, bearing to target, anchor watch and a warning when you enter a quiet zone.
Offline map of your lake – even without reception. Harbours, moorings, slipways & cranes, rigging masts, steamer piers and points of interest. Storm-warning lights, buoys and – depending on the lake – recorded shoals at a glance, bearing to target and “nearest safe harbour”.
Record trips by GPS – distance, duration, speed and course. Digital logbook with route, crew, weather and notes. Runs in the background. Recording and keeping all your trips stays free for good.
Anchor watch with a loud alarm if the boat drags – even when the device is locked. Man-overboard function, shore warning while recording, severe-weather alerts, emergency numbers and sea-rescue resources. All of it free.
Forecast and wind from the German Weather Service, plus the ICON-D2 and ICON-EU models. Current water temperature, water level and flood alert stages, sunrise and sunset, plus live webcams from the shore.
Quiet and protection zones on the map – with an optional warning when entering. Anchor zones for overnight stays on board. Nature conservation, right of way, navigation rules and the storm-warning system, clearly explained.
Virtual regatta with Yardstick scoring, regatta calendar, boat management with a maintenance log, light & dark design, freely selectable units (knots/km/h, °C/°F) and home-screen widgets. Your data stays on your device.
Everything that protects you and your boat is free for good – and stays that way. You only pay for what makes the sailing day nicer: one-off, no subscription.
Buy once, for every lake and for good. No subscription, no follow-up costs.
All information without guarantee. The range of features can differ from lake to lake, depending on which data is available for the cruising ground in question (e.g. webcams, gauges, protection zones or regattas).
All content consists of simplified summaries for general information only. It does not replace official nautical charts, official navigation or your own seamanlike judgement. Use is at your own risk.
“A lovely, clearly laid-out app that brings together everything that matters.”
Klaus Gattinger, professional sailor – in the Kreisbote, 15 August 2026
