New NAVTEX App for iPhone and iPad
One of our AIS contributors, Duarte in Portugal, has recently written an interesting and unique marine navigation app that we thought we should let our readers know about. It allows you to view Navtex information directly on your iPhone or iPad without needing an HF radio on board. NAVTEX provides navigational and meteorological warnings and forecasts, as well as urgent maritime safety information to ships. You can download Navtex for free from the App Store here:- https://itunes.apple.com/us/app/navtex/id1065285995 . You can also try out all the features for free for a week.
There is a short video clip showing what the app can do here:-
https://www.youtube.com/watch?v=wx-um26WoDE&authuser=0
and here is what Duarte has to say about his app:-
Navtex should be a requirement to any mariner, hobbyist or professional, regardless the type and size of vessel as it offers important Navigation Warnings that are safety-related while at sea.
Nearly 200 NAVTEX Radio Stations across the world form a global coverage network transmitting messages either in 490kHz, 518kHz, 4209.5kHz, 424kHz and 486kHz.
At sea, safety is everything so our Navtex App will fetch the latest NAVTEX messages issued by the several official entities and present them to you whenever you want.
You don’t need to connect your iPhone/iPad to any HF Radio. Only an internet connection is required. Synchronize and within seconds you have the worldwide updated Navtex information in your pocket.
You may select any of the available NAVTEX stations in the App and check their transmission schedule, frequencies, local data and latest important transmitted messages.
The Navtex Navigational Warnings will be collected from the internet and will be stored on your device, so you can read them even if you are off-line.
In Brazil, Australia and New Zeeland Navigation Warnings are not broadcasted via NAVTEX. However, this App will still fetch the latest Navigation Warnings from those regions and show them to you.
Additionally, you can also subscribe to APRS weather that is broadcasted by ham radio enthusiasts all over the world. It is a good backup system to gather weather information in case of failure of the vessels’s primary systems.
ActiveCaptain with SeaNav and BoatWatch
The latest versions of our SeaNav and BoatWatch iOS apps now include the fabulous ActiveCaptain database providing on and off-line access to information on tens of thousands of marinas, anchorages, hazards and local knowledge (bridges, locks etc.) , as well as reviews from other boaters, shown geographically on marine charts, satellite images, or street maps. The ActiveCaptain coverage is global. There is information on Marinas and Harbour side restaurants etc. from around the world including the US, Canada, UK, France, Spain etc. . If you aren’t already signed up for ActiveCaptain you can do it for free in a few seconds here:-
https://activecaptain.com/register.php
We found Jeff at ActiveCaptain really supportive and helpful on the integration with his data and had some lovely comments back from him on how well we did it too “The Pocket Mariner developers have been exceptional to work with. They are real boaters who get out on the water with their own tools.” Jeffrey Siegel, ActiveCaptain.
We look forward to adding more features and the ability to post reviews from our apps too in the near future.
Hoegh Osaka – replay of grounding in 2 and 3D
We used our AIS Fleetwatch service to replay the final moments before the Hoegh Osaka was deliberately grounded on Bramble Bank in Southampton. You can watch the speeded up replay on 2D and 3D here http://youtu.be/5fW_LRDWUPo . Interestingly our replay correctly shows the ship heading onto the bank in a Northerly direction before she grounds. Other replays incorrectly show her moving sideways onto the bank. It may be that the gyros failed on the ship just before she started listing badly resulting in the list and an incorrect ship’s heading being sent.
New AIS Aerial at Davidstow Airfield, Cornwall
As part of the ongoing work to improve our global AIS coverage we have installed a new AIS aerial to provide better real time coverage for the seas around Cornwall in the UK. There is a disused airfield at Davidstow. It was Coastal Command’s highest airfield in the UK at 300m (1000′) above sea level; a perfect place to get a long range view of the surrounding sea, to the North, West and South of Cornwall. We used a Digital Yacht AIS Net base station for the AIS receiver with a Shakespeare 6db AIS tuned aerial. There is no internet connection at the museum so we used a Huawei E3551 3G dongle and the excellent EE 3/4G data service to backhaul the AIS data to our servers. You can check the live coverage from the new aerial here:- http://boatbeaconapp.com/station/5353
Here is my son installing the aerial on the tower at the airfield.
The DY AIS receiver hooked up at the base of the aerial.
and live ships – 10,000 square miles of coverage including two major ports at Falmouth and Plymouth 🙂
Many thanks to Steve at Davidstow Airfield and Cornwall at War Museum who is kindly letting us use his tower to mount the aerial on (giving us another 12m (40′) of elevation 🙂 . The museum is very well worth visiting if you are in the area and even if you are not.
AISWatch – Live AIS monitoring with geofences and instant history replay
Pocket Mariner’s AISWatch service automatically monitors vessel movements and AIS SARTs in real-time using easily customisable geofences with audible and visual alerts. All AIS data is recorded and our industry first AISWatch instant replay service allows operators to retrieve data and instantly review events for incident analysis, marketing and training purposes. The AISWatch system is cloud based with easily accessible web views to display the live AIS positions and geofence states over chart or satellite maps. The same web view is also used to replay AIS scenarios from the stored AIS data.
AISWatch’s state of the art and cost effective port, ship, fleet and asset management services and apps including our industry first cloud based “Instant history playback” are used by Offshore platforms, Ports, Harbour Authorities, Fleet Managers, Marine Services companies and Shipping Agents. Our customer roster includes Portsmouth International Port , Bristol Port Company Avonmouth, Nautisk, Transas, James Fisher, E.ON, Scottish Power Renewables, RWE Innogy, SevenCs, Solis Marine and nauticAi. We also provide our AIS Watch service to Search and Rescue organisations like the RNLI , SARA and the AVCG which they use for tracking and training purposes.
More details on the AISWatch service are provided below. If you are interested in learning more or have any questions please contact us at business@pocketmariner.com .
AISWatch in use at Bristol Port Company operations centre. Showing 3D live AIS views.
AISWatch Live view lets you monitor the current situation and geofence status on a live chart web view. Real-time ship positions and AIS targets with tracks, information and photos. 2D and 3D views available. Hydrographic office charts with customisable chart overlays and objects ( cables, pipelines, station etc.)
AISWatch Geofences allow you to easily create and edit real-time visual and audible alerts for area entry, exit , crossing , status (arrivals and departures), SART MOB, AtoN Off Position etc.. using a simple and easy to use visual web based map view.
AISWatch Playback allows you to replay all shipping movements in your area instantly from any time in the past to assist with event investigation, resource utilisation, market research, training etc. Playback can be run at normal time or faster and supports forward and backward time “Scrubbing” allowing you to view an hours data in seconds to quickly determine the event you are looking for. Our live and historical AIS feeds can be also used to power other navigation systems such as those on Portable Pilot Units (PPUs) and other monitoring equipment.
Our professional services team can rapidly provide customised and tailored solutions for specific requirements and purposes.
You can try our history playback service in action here in 2D – boatbeaconapp.com/aisdemo – use the slider at the bottom left to move backwards and forwards in time and press the play button to play forwards. You can also see our 3D playback in action with this replay of the Hoegh Osaka grounding in 2015 – double click on a ship to fly in close up and then use your mouse to change the zoom (scroll) and viewpoint.
Pocket Mariner also provide global real time AIS monitoring and surveillance for ships far out of reach of shore based AIS systems using our innovative Internet over Satellite AIS (iSAIS) service. with 98% global coverage (using Inmarsat services).
1. Live view
Real-time ship positions with tracks, information and photos. 2D and 3D views available. Hydrographic office charts with customisable chart overlays and objects ( cables, pipelines, station etc.)
AISWatch monitors and records live ship positions via our local and global AIS services and when an event is triggered, forwards an alert via email and optionally SMS. The alert email includes details on the alert including maps of the alert area and ships around the ship’s current position. These maps can also be viewed via the web interface in 2D and our 3D service.
Our real time AIS feeds can also be used to power network aware AIS marine applications and systems such as our own SeaNav AIS Marine Charts and Navigation apps and third party systems like Portable Pilot Units (e.g. Transas’s Pilot Pro and SevenCs Orca G2 pilot. ).
2. Geofences
Geofences let you configure alerts for all ships (Zone Alerts) or your specific fleet of ships and AtoN’s (Fleet Alerts). Fleet alerts are not confined to your zone of interest. They can be set anywhere in the world subject to our system having live coverage of the region. Many different alerts are available from entering or leaving an area, crossing a line, arrival and departure (status), anchor watch, proximity, collision, SART, AtoN off position etc. Mobile Geofences can also be attached to moving ships and objects. When an alert fires an email/SMS is sent to all the alert addresses containing details for the event including a map of what and where triggered the event and a second map showing the ship’s current position.
You can create and edit the fences using this management screen or using our interactive map. Just click on the view fences button top left on either the Fleet Alerts or Port Alerts screens.
Tap View fences near the top left to view you currently configured fences on the chart. You can also edit existing fences by tapping on them and create new fences using the drawing tools. Rectangular, circular and polygon geofences are all supported (see example green fence areas below).
In the detail view for an alert you can also see the geofence alert position on a map to help you identify and set it.
As well as sending alerts to email addresses all Alerts are recorded in the searchable Events table. Tap on an event and see a map showing where and when it happened. Alternatively you can use the Ships tab to see details on the most recent events for a ship. Tap on an event to see a map of where it fired and the geofence area that it triggered.
3. Instant History replay – playing back ship movements and events
AISWatch records all the time stamped AIS data for your port or area of interest second by second. The data is securely stored in our highly available (99.995%) and redundant cloud based computing platform for as long as you want from months to years or forever. You can retrieve ship movements from any day and time in your AISWatch past instantly at the click of a mouse button using a calendar picker and then replay them on our web map view and via dedicated internet ports to other AIS apps like our iOS and Mac SeaNav chart plotter with ENC vector charts and other marine navigation apps like on of our partners SevenCs’ Orca G2 Pilot (PC display with Vector charts).
When the AIS playback is running it also outputs the recorded AIS data stream over a dedicated TCP port so that you can connect other apps and devices to view it. The playback also has our unique enhanced Type 5 AIS messages added so the static data for ships show immediately a ship appears rather than waiting for the static AIS messages to be re-sent (which can take up to 6 minutes to receive).
Fast scrubbing playback view (see live demo here http://boatbeaconapp.com/fleetwatchdemo)
On the fast scrubbing view you can use the slide at the bottom left to scroll back and forth through the whole period. You can also press play to playback from the current scrubbing position.
External app (SeaNav) driven from AISWatch Playback using the TCP connection.
Output from the playbacks can also be captured to video for viewing again independently of the AISWatch service. We recommend using the excellent and free VLC app on PC’s to capture the video or Apple’s free QuickTime app to record the screen on Macs.
You can see an example of a short video recording (1.5 minutes) replaying the arrival and docking of the Normandie ferry at Portsmouth International Port here :- Watch now

New NAVIOTAB+ tablet with built-in Boat Beacon for AIS
We have been working with IntelliWeather Inc. who have been developing an exciting new marine-rated rugged and waterproof navigation tablet device. The device is now launched and we are delighted they chose to build in our Boat Beacon AIS – Marine Navigation app to provide a fully operational AIS collision avoidance system. Here are some more details on this exciting new device.
A new IP66 rated waterproof and dirtproof Android tablet for marine use provides an all-in-one solution at a fraction of the cost of traditional separate marine electronic devices. It provides navigation, AIS collision avoidance, weather radar, weather bulletins, communications, entertainment, and optional fish finder/sounding capability in one portable device.
The NAVIOTAB+ tablet has been introduced by IntelliWeather Inc., a provider of weather instrumentation, weather display systems, and weather content and comes pre-loaded with ready to run applications and navigation charts for the United States. The user has options to purchase additional navigation charts for most regions of the world provided by Navionics. In addition, in an agreement with PocketMariner of the United Kingdom, the NAVIOTAB+ comes ready to use with a fully operational AIS collision avoidance system. Making use of the built-in GPS and Internet connectivity capabilities to provide a real-time AIS radar like display of vessels near your position in highly trafficked ports and navigable waterways worldwide. This provides an extra level of accuracy and protection allowing you to “see and be seen” with or without MMSI registration.
The NAVIOTAB+ also comes equipped with free weather radar plots and weather bulletins in the USA, including marine weather bulletins. The data is provided free by NOAA and has no subscription requirements. All that is required for live weather radar data and live AIS is an Internet connection via the built-in 3G/4G data capability of the NAVIOTAB+. This can be via a SIM card and most any cellular data carrier that supports a “bring your own” plan for connectivity. Alternately, NAVIOTAB+ can communicate via any 3G/4G capable cellphone that is WiFi hotspot enabled, or any other WiFi Internet connection.
When equipped with a SIM card and cellular data/voice plan, users can initiate and receive telephone calls using the built-in speaker/microphone, earphone, or use a Bluetooth enabled speaker or headset like they would with any cell-phone. Web browsing, email, and MMS messaging are also standard features.
As an entertainment system, NAVIOTAB+ provides a built-in FM radio tuner as well as streaming music services such as Pandora Internet Radio (free) and Sirius XM radio (subscription). Both come installed and can be operated without external antennas. Movies can also be played from streaming services such as YouTube, Netflix, Hulu, and others as well as locally stored files.
Unlike traditional marine electronics, the NAVIOTAB+ is not married to your boat, it can be taken “on the go” anywhere as a regular tablet and can also serve as an automobile navigation system via the built-in Google Maps application.
To round out the features, with the addition of a DEEPER Bluetooth enabled transducer, fish finding, water temperature, and depth sounding capability can be added to the NAVIOTAB+.
A powerful 10,000 mAH Lithium-Ion battery provides operation which can exceed 8 hours. The tablet can also be continuously charged/powered directly from your boat via the included Blue Sea Systems marine rated 12 volt cigarette lighter to USB power adapter and the included USB power cable.
Sporting a Quad-core 1.2 GHz A9 processor, 1 GB of RAM, and 8GB of FLASH storage, the NAVIOTAB+ is fast and responsive. Storage can be expanded up to an additional 32GB with insertion of a micro SD storage card. The bright 7″ screen is protected by toughened scratch resistant glass and can be seen in daylight, plus offers automatic dimming for night use. The built-in GPS receiver system does not require an external antenna, and is accurate to within 3 meters (10 feet).
Weighing just 1.36 pounds, NAVIOTAB+ is easily portable, and easy to secure to windshields, dashboards, and rails with a wide variety of readily available tablet mounting systems. It also comes with a palm rest/strap to enable portable use.
Tally up and compare the cost of all the separate marine rated devices that are replaced by the NAVIOTAB+ and you’ll understand why it makes the most sense for the recreational boater that doesn’t want to spend a fortune on getting their boat equipped. For the professional mariner, NAVIOTAB+ also makes a great backup system for your bridge, or as an emergency navigation system.
The NAVIOTAB+ has a manufacturer’s suggested retail price of $649.00.
Dealer inquiries are invited.

Adding a set of waypoints or marks in SeaNav
Here is how to import a list of Latitude and Longitude positions as a set of waypoints and route into SeaNav.
Step 1. Create a spreadsheet with the Latitudes and Longitudes either in Degrees, Minutes, Seconds, Degrees Minutes or Decimal degrees with a header line including latitude and longitude and a name field like so:-
Latitude | Longitude | Name |
28 52.634 N | 95 14.139W | Test 1 |
43°38’19.39″N | 116°14’28.86″W | Buoy 2 |
43 38 19.39 | -116 14 28.86 | SBH Buoy |
43.63871944 | -116.2413513 | Finish |
You can use any of the following formats for the coordinates
DMS, DM, Decimal Degrees etc.
DMS: 43°38’19.39″N
DMS with no symbols (use – sign for West or South): 43 38 19.39
DM : 28 52.634
Decimal degrees : 43.63871944444445
I use google docs to create the spreadsheet and then download it as an excel spreadsheet to my desktop.
Step 2. Then upload the xlsx file to
https://www.earthpoint.us/ExcelToKml.aspx (you do not need a login to use it)
By tapping choose file and browsing on your desktop to where you downloaded the spreadsheet. You can check it will convert ok before clicking “View on Google Earth” by tapping the “View file on web page, check for errors” button.
Step 3. Convert the kml to a kmz file. Simply compress/zip the resulting kml file and rename the extension from .zip to .kmz.
e.g. ClubMarks.kml -zip-> ClubMarks.kml.zip -re-name-> ClubMarks.kmz
and then email the kmz to yourself so you can pick it up in email on your iPhone.
Open it in the iPhone email client. Here are screenshots of the final step of the import process:-
Open the email and tap the kmz icon.
Press the button at the top right to import the file.
Select your flavor of SeaNav (UK, US ) from the list of options to open the file with:-
