Nautical miles
Example of one skipper
At the top is the one passage that takes you furthest: Split to Ancona, 112 nm overnight. Below it, what it changes for each requirement.
1 of 8 requirements for the Yachtmaster Offshore is met. Each stands on its own, with status and remainder: night passages, passages over 60 nm, nautical miles.
The nautical miles of the last ten years come from your recorded passages, five of five. Each can be traced back to its track.

Route planning
Example with a 46 ft charter yacht
Split to Ancona as a line on the map. You see where the night passage runs before you cast off.
Start and destination with distance, calculated with your yacht’s draught: 112 nm planned, 110 nm shortest navigable route.
Today, tomorrow or Thursday: duration and consumption per departure side by side, so you arrive in daylight.

Passage
Example of a skipper on the way to the next licence
Pick a station: six moments, six answers.
The problem
700 nm
For the SSS you need 700 sea miles after the SKS, for the Yachtmaster Offshore 2,500. Every single one must be documented. A paper mile log can’t do that.
With Loguna
Choose a goal, Loguna counts: sea miles, days, nights, passages over 60 miles.
2,500 nm
required for the Yachtmaster Offshore, plus 50 days at sea
A bar and the remainder for each requirement. The answer first: what is still missing?
1 line

The format examiners and charter bases expect. As a PDF, always free.
1 PDF
instead of a pile of papers at the exam
The problem
112 nm
Night passage to Ancona. When to leave to arrive in daylight? How much diesel if the wind drops? Three questions every chart answers separately.
With Loguna
Start, destination and track on the map, with your boat’s draught.
112 nm
overnight, on the map
Three times, three results: duration, consumption, diesel, arrival.
3 options
side by side, arriving in daylight
Wind, gusts and waves at the destination and on the way.
4 layers
wind, gusts, waves, temperature
The problem
4 h
An entry every four hours. At night, in a swell, with wet hands and a head torch. The paper logbook stays below, the entry is missing.
With Loguna
An entry in one tap: course, speed, wind, sails. Offline, sync later.
1 tap
per entry, even with wet hands
Position in the background, every mile. Gaps stay gaps, nothing is invented.
every mile
recorded, never interpolated
Dark, red, large. Survives a restart.
1 switch
that stays on at night
The problem
0 notes
The passage is done. Now it has to count: distance, duration, engine hours, who was on watch. Rebuilt from memory, it doesn’t count.
With Loguna
End with one tap. Distance, duration, engine hours: calculated, not estimated.
3 values
recorded, not reconstructed
The passage as a PDF: track, entries, weather, crew.
1 PDF
per passage, for base, owner or examiner
Who was on board, with role. Registered in Croatia before casting off.
150 €
fine in Croatia without registration. The list is ready beforehand.
The problem
2 years
Without the signature of the owner or skipper, no mile counts. Two years later, before the exam, you can’t reach them any more.
With Loguna
A link to the owner or crew, one tap. The passage is confirmed, right away.
1 link
instead of chasing them by phone
Licences, sea miles, confirmations on one sheet. For every charter base.
1 sheet
instead of folders, scans and emails
Mile log and CV as PDF, any time. Even after cancelling.
always free
no subscription needed, no lock-in
The problem
all passages
The night watch under the Milky Way, the dolphins off Vis, arriving at dawn. That doesn’t belong in an exam file. It belongs to you.
With Loguna
Every passage stays: track, entries, photos, weather. For good.
all passages
on one globe, still there in ten years
The passage as a page for crew and friends. After arrival, you decide.
1 link
for everyone who was on board
Whoever sailed with you stays in the book. You plan the next passage together.

Meilenbuch
Loguna shows, per licence, which requirements you meet and what is still missing, on this page with the RYA Yachtmaster Offshore as the example. Which sea time an examining body takes into account is its own decision. We provide the statement, showing where every line comes from.
With a link: after the trip you send it to your crew or co-skipper. Whoever was on board opens the trip view and confirms "I was there" with their own account, nothing more. The link is valid for 30 days.
Viewing and exporting your record costs nothing, even after you cancel. You add new passages with the Meilenbuch, paid yearly or monthly, at the prices listed above under Pricing. It is included in an operator’s fleet package.
We will name a date once it is fixed. Sign up and we will be in touch as soon as your access is ready.
