This manual describes version 2.2 of the Sailor Logbook S App - Free edition (note the S suffix) for iPhone and iPad - the version is shown at Start of App.

The Sailor Logbook S App is for sailors wanting:

It's the successor of the Sailor Logbook App - Paid edition (which has no S suffix).

Appetizers (top)

To give a quick impression of the App, a few examples on how it has been used follows.

Appetizer 1: daytrip in the Sound (top)

June 2017, at sea in the Sound between Denmark and Sweden, a daytrip was captured and shown via a tracklist:

The screenshot above is from an iPhone SE device, for which the App is optimized.

Appetizer 2: roundtrip through Sweden (top)

A roundtrip (june-july 2018) through Sweden was tracked. Below a Piechart showing use of sails during the first 6 tracks:

The whole trip was tracked as:

A report gives another picture - below a snippet of the report on the third day of the roundtrip:

On a small screen both horizontal and vertical scrolling is needed to see all the details. Maybe a print would be opportune. Alternatively, the report view can - like most other views and all maps - be pinched inwards (zoom out) and outwards (zoom in).

The contents of the logbook for a given time range can be assembled in a Breadtext page, and from there copied to the clipboard:


Appetizer 3: crossing the Biscaya (top)

Crossing Biscay (sept 2018, on board Costa Pacifica) was an offshore rite of passage like no other. Luckily it was calm weather!

There must have been a very strong with-going ocean current in the English Channel!

Basics (top)

While tracking, whenever a movement of between 10 and 200 meter has happened, the App makes and saves a plot with location and a timestamp. Plots are used for drawing track sections.

Every time you have moved 10 meter, the App compares the current location with a line through the two last saved plots, to determine whether it should saved as a plot as well. The very first two locations are saved as plots. If you thereafter follow a straight line, a plot is saved each 200 meter. If your track bends, plots are saved more frequently.

During tracking, you have the opportunity to create events (aka user events) with miscellaneous registrations. An event is a collection of observations and doings. Each of these is recorded in an event attribute - e.g. the doing of setting Full sails is recorded as a value in a Sails attribute.

When an event is created, the App forces the GPS to make a plot to attach to. Events are represented in maps as colored pins, and in lists and reports as colored cells. They can be accessed from both maps and lists for inspection, editing and (with exceptions) deletion.

Track title and free-form textfield comments may be entered and edited at any time. All textfields are optional.

The current track is the track that's being tracked. It can be shown in a live map, and edited.

When tracking is ended, the current track is moved to a collection of historic tracks. These can be listed, searched, shown on maps and in reports, and edited almost without limitation - like a current track. Historic tracks are kept as long as you wish and have memory on your device.

Historic tracks can be uploaded to the Sailor Logbook Website, after which they are kept in a frozen state in the App - i.e. they cannot be edited any longer, only shown and deleted. At the Website, they can still be edited - and deleted if you want. Track states are:

At the Website, tracks are transformed into cruises which can be edited. If an uploaded track is deleted from the App, it may be recreated by a download, whereby such edits are included.

If you have a Website account, more devices can all be connected to that via the App.

Hardware (top)

Tracking is only feasible on devices with built in GPS hardware, i.e. on all iPhones and iPads with the cellular option.

iPads without GPS (without cellular option) can't do any tracking, though they may still download tracks from the Website to display these on maps and in lists.

The App is designed to work on devices from small screens (4" on iPhone SE and iPhone 5) and up. Larger screens - like the iPad - of course have benefits, especially when showing maps. However, the App functions identically on all devices.

Restrictions (top)

The only way to backup, restore and replicate your tracks to other devices is via the Website. To do this, you have to Subscribe.

Whenever the designation map occurs, the reference is to land map - i.e. sea maps are not supported. The Sailor Logbook S App uses Apple maps, and the Website uses Google maps.

There is no support of taking photos inside the App. However, photos taken with the camera App - or other - can be uploaded to the Website, using functions there.

Though the App works on both small and large screens, this manual is best read on a large screen.

Precautions (top)

When tracking, the GPS does consume a considerable amount of battery power. Therefore it's recommended that your device is connected to a power source when doing prolonged tracking.

For upload to and download from the Website to work - as well as showing maps - network connection is needed. This may be through wifi (all iOS devices) or mobile network (all iPhones and iPads with the cellular option).


The simulator (top)

As basis for many - but not all - of the screenshots in this manual, a simulator rather than a real device was used. Simulated tracks are determined by Apple developers. None of these tracks are at sea, so you must abstract from that.
