The app in practice
What YachtLog can do
Navismare has been delivering yachts worldwide since 1996 – on their own keel, with professional skippers. YachtLog bundles the tools that have proven themselves along the way: from passage preparation and navigation to safety and the skipper-confirmed PDF logbook. Features marked PRO belong to the PRO version – everything else is free.
🎛️ Cockpit dashboard
Trip data, fuel status and key figures at a glance: speed, engine hours, remaining distance, range and refuelling advice – engine and sailing miles shown separately.
📄 One-tap logbook
Ten manoeuvres from casting off to mooring – every entry automatically records GPS position, timestamp and weather. At the end of the trip the skipper reviews and confirms the logbook.
🗺️ Live course chart
Sea chart with your track, the planned route and a satellite view. Seamarks – buoys, lights, hazards – come from an on-board database covering all of Europe, work offline and show light character, colour and position when tapped. With PRO the chart tiles work fully offline too – simply cache the route before casting off.
🧭 Route editor & harbours PRO
More than 11,600 harbours from the Baltic to the Caribbean: build your route on a nautical chart with seamarks – plus the route library with as many saved routes as you like, in sync via iCloud, and GPX import/export for iSailor and Navionics.
⛽ Fuel advisor PRO
Calculates consumption, reserve and coverage for the planned route depending on your passage profile (offshore, coastal, motor yacht) – with a clear refuelling recommendation before departure.
👥 Watch schedule & briefing PRO
A fair watch schedule for 2–6 crew members with preferred times – the skipper is automatically spared the dog watch. Plus role assignments, printable safety briefing and provisioning list.
🍲 Provision planner PRO
A meal plan for the whole trip at the tap of a button: 30 galley-proven dishes matched to fridge, freezer and gas consumption – with an automatic shopping list scaled to your crew, split into pre-departure shopping and restocking underway on coastal trips.
🌤️ Marine weather & storm alerts
Hourly forecast along the planned route, GRIB wind arrows directly on the chart and automatic warnings. The full Windy weather map comes with PRO.
🌊 Tides & passages PRO
48-hour tide curve worldwide, GPS-based or by place search – plus optimal transit windows for five notoriously tricky straits, from the Alderney Race to the Strait of Dover.
🆘 Man overboard (MOB)
One tap freezes the GPS position, starts the alarm, shows the live bearing back to the MOB position and a quick-stop guide.
⚓ Anchor alarm
GPS alarm when the boat leaves the set radius (25–500 m) – with sound and push notification, even when the screen is locked.
📱 Live Activities
Your trip and anchor watch right on the lock screen and in the Dynamic Island: speed, course, distance to destination, trip time and fuel used since departure – or anchor distance and alarm status. Without opening the app.
🧾 Sea miles certificate PRO
Proof of sea miles for every crew member: select the trips, state the role on board – done is the A4 PDF with all passages, distances, totals and signature fields for skipper and crew.
🤝 Handover protocol PRO
Taking over and returning the yacht, cleanly documented: a checklist in six areas, defect notes, damage photos and signatures right on the display. The return carries over pre-existing damage automatically – the A4 PDF convinces charter companies and owners alike.
🚨 Emergency card & PAN-PAN
The SOS button creates an emergency card to IMO standard: pre-worded MAYDAY call with NATO spelling, vessel data, position, crew list and MRCC numbers. PAN-PAN positions can be marked directly on the chart.
☁️ Archive, PDF & iCloud PRO
Completed trips with chart and statistics in the archive, an official PDF logbook with the Navismare stamp – and all data in sync on iPhone, iPad and Mac via iCloud.
