SeaNav – Marine Charts & Nautical Navigation App for Mac OS X

The newest member of the SeaNav app family brings our acclaimed marine charts to Mac – letting you explore and plan your boating trips on your Mac, then export your route to your iPhone for navigation while at sea – or plug in a GPS unit, and navigate with your laptop and our hi-res vector charts. SeaNav for Mac US has the latest NOAA ENC Digital Vector Marine charts covering the whole of the USA and Great Lakes, SeaNav for Mac UK has the latest UKHO UK and Ireland vector charts. SeaNav for Mac is exclusively available on the Mac App Store.

Includes NOAA US Coastal, Great Lakes and USACE Inland Charts.
Buoys, lights etc. are tappable with bearing and distance.
Seamless fast panning and zooming across charts.
Route Planning and tracking with Waypoints, SOG, COG, ETA etc.
Charts work offline
Route export, import and sharing (KML, share via disk or Dropbox)
Live AIS Ship positions
Share routes and tracks with SeaNav on iPhone and iPad

SeaNav uses the latest Digital Vector charts providing a wealth of benefits and advantages over raster charts. Buoys, Lights, Bridges, Depth Contours, Depth Soundings, Rocks, Anchorage areas, NOAA Weather Buoys etc. are all selectable and have real time distance, bearing and detail information. Turn off layers to de-clutter the display and only show what is important at the time. Tides, moon and sun times and weather are also all available at your fingertips.

SeaNav lets you measure distances and bearings and record waypoints on routes. When at sea, the app’s Sailing HUD shows your position, Course over ground (COG), Speed over ground (SOG), Vector Made Good (VMG), Estimated Time of Arrival (ETA), Distance and bearing to next Waypoint. Waypoint reached alerts, auto-routing to the next waypoint and collision alerts.

SeaNav is also available for iOS, so you can plan a route on your Mac and share the route with your iPhone or iPad – or take your iPhone sailing, then send your track back to your Mac.

Plug in your GPS unit and go – SeaNav works with Bluetooth and serial GPS units, and those which provide location or AIS service via TCP or UDP or TCP, including devices from Lowrance, Simrad and B&G GoFree. But GPS is only required for real time route navigation, you can plan routes without GPS then send them to your iPhone for use while at sea. SeaNav’s optional Real time AIS, Tides and Weather information require an active internet connection.

Your purchase of SeaNav includes 12 months free updates to the included US chart set.

SeaNav for Mac is exclusively available on the Mac App Store.

Navionics Boating (free US NOAA Charts) vs SeaNav

Navionics have launched a new version (7.0) of their Navionics Boating app which now includes free US NOAA vector charts. If you are boating in the US you can now get a well respected and functional marine navigation app on your iPad and iPhone without spending a cent. What are they up to? Why should you go anywhere else? How can they give away a full blown marine navigation app for free? We hope the following comparison and charts around San Francisco can help you decide which route to follow.

Here is the view of San Francisco from SeaNav within a 3 mile radius – the horizon for most leisure boat users (6NM x 6NM square) :-

and the same scale on Navionics Boating with their free NOAA charts :-

What?

We zoomed in and eventually (at three times the scale) details appeared:-

Compare this with SeaNav at the same scale:-

We hope you will agree that its a lot less cluttered, has more relevant information and is a lot easier to view. Zoom in and more details and spot depths will be shown. You can also choose what level of detail to show in SeaNav.

Other key differences:-

SeaNav includes full live navigation features including COG, SOG, HDG, ETA, Waypoint distance and time, Cross Track error, Course and North up view etc. – it’s at least a $5 extra for Navionics and that doesn’t get you much of what SeaNav offers.
SeaNav includes Tides – Navionics Boating free doesn’t – you have to buy their USA chart set at $70.
SeaNav has a unique and highly recommended AR Camera view showing buoys, ships, landmarks etc. overlaid on the real time camera view.
SeaNav has free support for the amazing fully waterproof Pebble SmartWatch – forget a $500 Garmin Quatix!
SeaNav has live AIS Ship data overlay including collision detection. (via Boat Beacon).
SeaNav – buy once and runs at full HD on both your iPad and iPhone with no need to purchase another version.
SeaNav including full charts is just $19.99 in the US and £14.99 in the UK. See how this unfortunate user ended up paying over £70 ($100) for Navionics “Free”:-

Boat Beacon now supports AIS and GPS from a VHF AIS receiver.

Boat Beacon now allows you to use AIS and GPS NMEA data directly from an AIS receiver and GPS on-board your boat via WiFi (over UDP or TCP) or Serial(USB). Boat Beacon seamlessly combines this with the AIS information it receives over the internet. If you travel outside mobile internet coverage or in an area where we don’t have good coverage from a local shore station, Boat Beacon can now continue to work displaying live ship data, calculating Closest Point of Approach (CPA) with alarms etc. from your VHF AIS receiver or AIS enabled VHF radio. On Android you can connect the NMEA serial or usb output from an AIS receiver or connect via WiFi. On iPhone you need to use WiFi. Here are some of the AIS receivers we have tested with Lowrance, Simrad, B&G, Digital Yacht, Comar NMEA-w2-Wifi, Weatherdock EasyAIS, Chetco Digital SeaSmart , dAISy AIS, Navico GoFree, Quark AIS (dual channel and usb stick) etc. More information on how to hook all this up is given below.

iPhone and Android AIS and GPS over WiFi.

If you already have AIS data available over Wifi on board then just enter the UDP port number (or ip address and port number for TCP) for the source and Boat Beacon will start using the data. With Navico GoFree and iPhone/iPad this is even more simple as there is a “GoFree” connect button in settings – just press and go. If you only have a usb or nmea output available you will also need a serial or usb to internet or Wifi adaptor. They range in price from $50 to $200. This is one example we have tested with at the $70 level – USR-TCP232-400 that we hook into our on-board WiFi hub.

Here are some specific instructions for connecting Boat Beacon on Android to GoFree – http://pocketmariner.com/?p=1538

Android AIS NMEA 0183 and GPS over USB or serial

Boat Beacon will automatically launch and use local AIS data (and GPS if available) when a USB cable is plugged in between the AIS receiver and your Android device. You can set the USB mode on or off in settings in Boat Beacon.

For an Android NMEA 0183 connection you will need the following:-

1. An Android device that supports USB host mode (typically OS3 or later)

2. If your receiver doesn’t have a USB output you can simply convert the NMEA 0183 2 wire output to USB for a few dollars more using an RS232 to USB cable. Typically $7 or so. The most common USB to RS232 cables use the Prolific 2303 driver which we support. The cable we tested with is this one :-

http://www.amazon.com/dp/B00425S1H8/ref=cm_sw_su_dp

We also support many other serial usb drivers (see below).

3. You will also need an Android OTG micro usb adaptor which only cost a couple of dollars. Here are a couple of links to the type of OTG micro usb adapter you will need:-

http://www.amazon.co.uk/female-Micro-Adapter-Cable-Function/dp/B009DFCCKO/ref=cm_sw_em_r_awd_iuSgtb100Z2YZ_tt

and this one allows you to charge your device at the same time:-

20 cm Micro USB OTG Y-Cable + extra power supply http://www.amazon.co.uk/dp/B00EJP5XR2/ref=cm_sw_r_tw_awdl_adfhtb0B8YQ4B via @amazon

More information.

You can get Boat Beacon from the iTunes or Android stores – Boat Beacon

If you have a problem connecting with Android over usb you can run this free simple serial usb tester program on your Android device once you have an OTG adaptor to report and test what driver is required and let us know :-

http://boatbeaconapp.com/ybw/app/usbtest.apk (just click on the link on your tablet to download the app).

Please email us if you have any questions or suggestions at support@pocketmariner.com

There is also a great article here about hooking up NMEA to serial :- http://cms.nobeltec.com/CMS/Files/Connecting%20instrument%20serially%20to%20the%20computer.pdf

SeaNav brings unique Augmented Reality Live View

Augmented Reality View

Our unique AR view mode allows you to view buoys, lights, ships, waypoints and track overlaid on your iPhone or iPad live camera view. With “AR LockOn” you can select a target on the chart and then be guided to it in the AR camera view.

Find that ship on the horizon and instantly see its name, range and bearing.
Spot the next marker buoy.
See your route and next waypoint

Tap the “eye” icon at the top left to switch AR mode on, then tilt your device up to see a live camera of the scene and boats around you. As you turn round and view buoys and ships, their name, range and bearing will popup when they are in the center of the view. You can also tap on them to get more information. Tilt back down to see the map view. Tapping the “eye” icon again turns AR mode off. You can pinch to zoom the map or camera views.

In AR mode our unique “AR Lock On” feature lets you select a ship or buoy on the map view and then easily locate it in the Camera view using a grey arrow to tell you which way to turn to spot it when its not directly in view. Your course (yellow line) and route to next waypoint (blue line) will also be visible overlayed on the camera view.

Ships are color coded based on their type e.g. Sailing boats are white, Pleasure Craft magenta, etc. See the Map Legend for full details. A vector points forward showing where each boat will be in 2 minutes time based on its current Speed and Course. Ships move in real time across the map and in the AR view. Tap on a ship or buoy to get more information and tap on the right arrow to get even more including speed, course, distance, bearing, picture etc. The horizon is set by the zoom scale of the chart view – e.g. zoom out on the chart view to see further out in the Augmented reality view.

Improved real time AIS Coverage for the Solent and English Channel

Our network of AIS coverage around the world is amongst the best in the industry. However we are always looking to add new areas and improve existing ones.

Thanks to John Ambler on the Isle of Wight sharing his AIS data directly to our servers our users now have greatly improved real time coverage around the Solent and English Channel.

Here’s a screenshot showing the range of ships his receiver is picking up from an aerial 200 feet above sea level on the island.

You can check the live coverage on John’s web page and in real time on Boat Beacon and SeaNav too.

A big thank you to John and complimentary copies of all our marine apps.

Sea Trials – Sailing with SeaNav, Boat Beacon and Boat Watch – Day 2

Another sea trial today. Out of Portishead Harbour up channel to the Second Servern Crossing and back on the turn of the tide.

No “sinkings or drownings” though a lot of diesel fumes and some litres lost due to the fuel tank filler nozzle fracturing off in the “moderate to severe” seas in force 5/6 – spray right over the top of the boat and front of the boat completely under water at times! A bit of a baptism of fire for my young son, but he coped admirably.

We had 3 serious close encounters with a large dredger off Avonmouth that Boat Beacon really helped with. First off, Boat Beacon started flashing that the dredger was on a collision course with us even though visually it looked like it was sideways on passing behind us. The currents are deceptive. We could find out the name of the ship immediately from Boat Beacon, UKD BLUEFIN, and thus radio it to ask what its intentions were. Unfortunately no reply on VHF channel 16. Then we heard another Boat call up the Bristol port authority (VTS) on channel 12 about the ship to ask what it was doing. If we hadn’t known the ship’s name we would not have appreciated the value of the subsequent radio dialogue. It was dredging just outside the port and would turn round to go back in to port to continue its dredging. So although we thought it was headed straight for us – it turned and went back and we carried on.

An hour later on our return down estuary to Portishead the ‘Death Star dredger’ BLUEFIN came out of Avonmouth yet again headed straight for us on our port side. We were hoping/thinking it might just turn around again to head back in to continue dredging. We radio’d the Port Authority to ask what its intentions were. No. This time it had finished dredging for the day and was really heading for us on its way to drop its load on the spoil ground off Portishead. So we made a speed and course change to pass behind it.

Home stretch. Sea state moderate , waves still breaking over the canopy, dredger on the horizon, sideways on to us and stationary on Boat Beacon, only 2NM to go to Portishead Marina. Time for a cup of tea. Alarm. Dreaded Dredger heading straight for us again! It had completed dumping and was returning to Avonmouth – at 10 Kts and 1 NM off. Time for a 90 degree course change. The challenge was whether to head out to sea towards Wales to pass port to port (accepted behaviour) or head in towards shallow water where the dredger should not go. Heading out risked missing Portishead altogether – we couldn’t beat the tide that was now running at 3 Kts- and might have to spend another 3 hours of heavy wind over tide waves to Cardiff. Boat Beacon gave me the confidence that we could make the dash for shallow water – which we did………(see red arrow on screen shot below)

The long straight white dotted track line leading North is the bug we discovered in the first day of Sea trials – fixed for the next release of SeaNav.
