One app, five cruising grounds

Your cruising ground, your chart

Lake Chiemsee, Lake Starnberg, the Ammersee, the Tegernsee and the Brombachsee – you pick your lake in the app and everything follows suit: its own nautical chart, its own harbours and jetties, its own zones, gauge, weather and webcams. Your trips stay neatly separated by cruising ground.

Lake Chiemsee

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.

Lake Starnberg

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.

Ammersee

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.

Tegernsee

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.

Brombachsee

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.

The app's chart – right here

This is not a picture but the real chart 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.

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.

Features

What Binnen Skipper can do

Chart & orientation

Offline nautical chart of your lake – even without reception. Harbours, moorings, slipways & cranes, rigging masts, steamer piers and points of interest. Storm-warning lights, shoals and buoys at a glance, bearing to target and “nearest safe harbour”.

Trip recording & logbook

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.

Safety on board

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.

Weather & water

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.

Nature & rules

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.

And more

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.

What costs what
