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:-
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.
Here are some tips/pointers from our initial experience of using the Apple Watch with our Boat Beacon app.
1. By default the Apple Watch shows a watch face when you raise your wrist to look at it. If you want to see your nav data on Boat Beacon you have to press the crown and select Boat Beacon. This is really annoying when you want to see your navigation information at the flick of your wrist. Fortunately there is an option in the Apple Watch app on your iPhone to ensure the Boat Beacon app (or whichever app you were using last ) stays on top – its in My Watch/General/Activate on Wrist Raise/Resume Previous Activity – make sure this is ticked.
2. You need Boat Beacon on your iPhone/iPad to be in Sailing mode (Sailing button bottom left selected) to get SOG, COG , Heading and CPA/AIS information on Boat Beacon’s watch app display. The same applies to our SeaNav Watch app which also has a Waypoints display.
3. iPhone Battery is draining much faster when SeaNav or Boat Beacon app has been run on my watch even though it is no longer being displayed on the watch and I am not running the apps on my phone/iPad.
The problem is that when you launch the SeaNav or Boat Beacon watch app (or in fact any app that needs gps) on your watch it stays running even when its not showing on the watch face and/or another app (e.g. the clock) is showing. As it is running it will keep asking the iPhone for gps info which will eat battery on your iPhone. The solution is to “Force stop” the SeaNav app on your Watch when you have finished using it. Here’s how to do this:-
With the SeaNav/Boat Beacon app showing on your Watch screen press and hold the side button below the Digital Crown for a few seconds. The next screen you see features buttons for Power Off, Power Reserve and Lock Device. When you see this screen press and hold the side button again until you see SeaNav disappear and be replaced by the home screen. There are more instructions for how to do a force stop here
We need a way to exit the SeaNav app on the watch more easily – either from the iPhone or more directly from within the SeaNav app running on the watch. This appears to be a mistake/oversight by Apple (a lot of folks with fitness and cycling apps are complaining to Apple about battery drain) and hopefully they will address it in a future release.
Just remember to force quit it on your Watch when you don’t need it running.
4. The wrist torch mode doesn’t work – looks like Apple won’t let the watch show a blank white screen (it worked in the simulator). We will take a look at how to get this working. For now you can use the AIS Map display to shed some light in the dark.
5. The watch screen is polarised to reduce glare and visibility is good on a bright day. Apple have got the polarisation right – just like on instrument displays on aircraft – it works fine with Polarised sunglasses. We tested with a pair of my son’s Ray-Ban Aviators and we could see the watch face fine.
With the help of a ShipPlotter user in Finland we have been able to run side by side tests of our Pocket Mariner Dual Channel AIS receiver with a mainstream commercial brand AIS receiver costing over 3 times the price. We are very pleased with the results, with the Pocket Mariner Dual Channel AIS receiver achieving almost exactly the same coverage/range/data rate of the well known commercial brand. Here are some stats comparing our Pocket Mariner AIS receiver on port 7018 (blue) and the other on port 5378 (red ) and screenshots at the same time of the coverage from the same aerial in Helsinki.
Rate of data received (bits/s)
We also found that the coverage/range for both the commercial AIS receiver and ours was significantly improved using a relatively in-expensive AIS frequency (162MHz) tuned filter and pre-amp on the aerial feed. We used and would recommend the VHF Pre-amp from Spectrum Communications (formerly known as the Garex pre-amp). They start at around £15 for the pcb built one and around £50 for a boxed version. The ship ranges in the screenshots below is approximately 150km (100Miles). The tropospheric conditions were good.

N.B. The buoys at the top of the screen (North) are over 350km away and most likely Synthetic Aids To Navigation being broadcast by a shore based station nearer our aerial.

Our ship tracking network uses a global network of shore and ship-based radio stations, which receive signals from the AIS system that ships use to broadcast their positions as they travel. Our receiver stations share the ship positions with our cloud-based data server, which pushes them onwards and out to our apps and web services.
We are continuously working on increasing the coverage of our real-time AIS receiver station network. During the last three months we have added more than 100 new AIS stations across 5 continents bringing our live ship coverage to over 40,000 ships. We have supplied the AIS receiver for free for many of these sites. New volunteers are always welcome to join our AIS Network.
Here is a list of the most recent stations we have set up and a snapshot of our global coverage Q2 2019
Hudson Bay, NJ
Sakonnet River in Rhode Island
St Lawrence Seaway
Miami, Florida, US (2 new stations)

Pocket Mariner are very pleased to be sponsoring the Row around Singapore Island in aid of the Mission to Seafarers .
A group of 40 enthusiasts from the maritime and insurance community in Singapore have come together, to undertake a 24 hour endurance sea challenge, all in aid of the global maritime welfare charity, The Mission to Seafarers.
Mission Row Around Singapore Island (RASI), will see two teams in ocean-going rowing boats attempt the 140km journey, taking on the seas and shipping lanes (not to mention two live military firing ranges) to complete a non-stop circumnavigation of the island of Singapore. The event itself will be held during the 50th anniversary year of Singapore’s independence and will also coincide with Singapore Maritime Week on the 22nd / 23rd April, 2015.
Pocket Mariner have provided their Boat Beacon app to both teams so they can share their position and speed during the event and everyone will be able to follow their progress on our live group tracking web view service.

If you are organising an event or a race and are interested in having live tracking available please contact us :- email@example.com
Watermark is a Beneteau First 33.7 Cruiser/ Racer currently on a round Britain voyage. She is using Boat Beacon to share her position over internet AIS with friends and family on Boat Watch and our new live iframe “embed” web page that lets you add a map showing your boat’s location to other web pages (e.g. a blog). Use the following as a template, you can set the width and height to fit your page
“<iframe style=”border:none;height:600px;width:1800px;” src=”http://boatbeaconapp.com/see/MMSI?embed=1″></iframe>”
Where MMSI is your boat’s MMSI number (as set in Boat Beacon). If you don’t have an MMSI, we can provide you with an internet AIS one, or you can use your Boat Beacon identity instead starting with BB (see the bottom of My Boat Details in Boat Beacon to find your Boat Beacon id). If you don’t have blog or web site you can also give out a web link to your web page on our site – e.g. http://boatbeaconapp.com/see/MMSI
We wish Malcolm and Watermark a safe and very enjoyable circumnavigation and look forward to following their progress. Here is his current postion :-
We have been working hard to ensure Apple Watch versions of all our marine apps are ready for you as soon as you get your new Apple Watch. Boat Beacon, our signature app, now gives you collision alerts directly on your wrist with CPA time and distance information and a map overview. Check your next waypoint wherever you are on your boat with a compass view, cross track error (XTE), distance and ETA on our SeaNav watch app. Spot nearby boats, track your ferry or a boat of interest and get arrival and departure alerts with our Boat Watch app on Apple Watch.

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.
