CoSkipper - Boat Assistant

CoSkipper is the purpose-built digital boat assistant for day-trippers, weekend boaters, and motorboat captains.

Want to head out on the water spontaneously, drop anchor in a quiet bay in the afternoon, and maybe spend a night on board? CoSkipper is made for exactly that. Forget bloated navigation apps and the constant switching between weather apps and water level websites. CoSkipper gives you everything you need for your short trip — on one clean, modern dashboard.

INTO THE SHALLOWS SAFELY — SMART SHALLOW WATER MANAGEMENT The most beautiful bays and backwaters are often shallow. Load live water levels from over 600 official stations (PEGELONLINE). Save shallow spots via GPS and the app compares today's water level with your boat's draft — colour-coded alerts before it gets too tight. Share those points with your fellow skippers!

SLEEP EASY WITH ANCHOR WATCH Staying overnight? Set your anchor point and define your swing circle (10–100 m). If your boat drags, the app sounds an immediate alarm — with a piercing siren and a push notification that overrides silent mode and Do Not Disturb.

WEATHER, WIND & THE GOLDEN HOUR 24-hour forecast with temperature, UV index, wind speed, and gusts. Keep an eye on sunset and let the built-in return-home alarm remind you in time.

LEAVE THE DOCK FASTER WITH CHECKLISTS Never forget anything important at the pontoon again. Use aviation-style checklists for your daily cruise (packing, pre-departure, arrival). Track your fuel levels and range at a glance.

NOTES & SOS IN AN EMERGENCY Save personal notes about your favourite routes. In an emergency, the dashboard instantly displays your exact GPS coordinates to read out on the radio — with one-tap dialling for DGzRS and water police.

PRIVACY FIRST & FULLY OFFLINE All your data is stored locally on your device only. No account required, no hidden tracking, no ads.
