Your entire voyage in your hands: route planning, crew briefing, sailing weather, logbook and kitty, before, during and after the trip.
Your whole sailing trip in one app – for skipper and crew.
From passage planning and sailing checklists to the ship kitty, sailing weather, your sailing logbook and mileage log: CoSkipper brings preparing and sailing your trip together in a single app.
BEFORE THE TRIP: PREPARED TOGETHER
No more group-chat chaos and scattered info.
• Passage planning: route and stops day by day on the map, with the distance for each leg
• Crew: invite your crew and share everything about the trip, the yacht charter and the boat in one place
• Packing lists and sailing checklists: personal packing lists, shared boat lists and templates for provisioning and check-in – so three Bluetooth speakers don't end up on board
• Safety briefing: go through it step by step, have the crew confirm they took part, export it as a PDF
SAILING WEATHER THAT UNDERSTANDS SAILING
Not just weather data, but an assessment for your leg.
• Sailing conditions rated: good, demanding or difficult
• Wind in Beaufort with gusts and your course to the wind
• Wave height, cross seas, rain and thunderstorm windows
• Shift your departure time and compare the expected arrival
• A warning before a planned night arrival
• Berth check: is the harbor sheltered from the expected wind?
DAILY BRIEFING FOR THE WHOLE CREW
Every morning the whole crew gets a briefing with the day's leg, the weather and everything coming up – right on their own phone.
SAFE AT SEA
• Safety briefing with a ready-made or your own template and PDF export
• VHF radio assistant for more than 25 typical situations, from MAYDAY to requesting a berth
• Radio calls pre-filled with your boat's details and current position
SAILING LOG: EXPERIENCE. CAPTURE. SHARE.
The best sailing trips are the ones you still remember years later – your sailing logbook keeps them.
• Boat log entries for departure, arrival, weather, incidents, notes and special moments
• Position and weather are saved with every entry automatically
• Course, distance and nautical miles sailed are recorded in your boat log
• Your trip's track on the map – look back on a single day or the whole trip
• Share recaps with the crew and export them for social media
MILEAGE LOG: ALL YOUR SEA MILES IN ONE PLACE
• Add the miles from a trip recap to your mileage log with one tap
• Record sailing area, route, boat and your role on board – skipper, co-skipper or crew
• Export your mileage log as a PDF and share it
SHIP KITTY
Track shared expenses in the ship kitty and split them transparently. At the end, CoSkipper works out who owes whom – no more receipts on scraps of paper.
FOR SKIPPER AND CREW
The skipper organizes and plans. The crew has all the info on their own phone, gets ready, takes part in the trip and relives it later through the trip recap. Whether it's a yacht charter with friends, a family sailing vacation or a weekend on your own boat: CoSkipper is with you from passage planning to the last nautical mile.
CoSkipper – your whole sailing trip in one app.
