In January of 1968,
the USS Pueblo a “technical research
vessel” (Navy Intelligence) was boarded and captured by North Korean
Forces. Initially the United States
attempted to deny, deny, deny. The claim
that it was not a spy ship was hampered by the fact that the ship with numerous
electronic appendages looked like a floating antenna farm. Today, the USS Pueblo remains the third-oldest commissioned ship in the
US Navy, and the only ship of the U.S. Navy currently being held captive.
Motivator’s Radar Arch
I only mention USS Pueblo because modern cruising
vessels are like the Pueblo in that
they are also floating antenna farms.
The Very High
Frequency (VHF) radio remains the cruiser’s primary means of
communications. It is used for ship to
ship and ship to shore communications.
Cruisers communicate with buddy boats and crew members in launches,
coordinate crossing situations, arrange dockage, receive weather information,
and conduct cruiser’s nets via the VHF radio.
Cruiser’s nets are established for a geographical area and are usually hosted
by volunteers. The Grenada Cruisers Net
is at 7:30 AM on International Channel 66 Monday through Saturday. The agenda is: Security & Navigation, Weather,
New Arrivals, Departing Vessels, Needed Parts and Services, Treasures from the
Bilge (items you wish to sell or give away), Social Announcements, Commercial
Announcements, and Items Missed. On most
mornings the net takes about 30 minutes.
Single Side Band
(SSB) radio is also popular among cruisers and unlike VHF allows for
communications over vast distances if atmospheric conditions permit. SSB allows cruisers to get weather
information, routing recommendations, participate in nets, and with extra
equipment send and receive emails.
Because of the equipment costs and the learning curve associated with
SSB, Motivator is not equipped. So far we have not needed SSB, and I think it
would only be necessary if we were crossing oceans or traveling to very remote
places.
The ship’s radar
becomes your eyes in fog or at night for identifying possible vessel traffic. Radar can also be used to verify your
position by comparing displayed land features with your navigational chart.
Motivator is alerting with Stop The Press
Automated Identification System (AIS) is relatively a newcomer to the
cruiser’s tool bag.
International
voyaging ships with gross tonnage of 300 or more tons are required to operate
with a Class A AIS transceiver.
In 2007,
the new Class B AIS standard was introduced which enabled a new generation of
low-cost AIS transceivers.
AIS is an automatic tracking system used
for identifying and locating vessels by electronically exchanging data with
other nearby ships and AIS Base stations. AIS information supplements radar.
Motivator
is equipped with a Class A & B receive only AIS system that displays
vessels identification, position, course, and speed on the navigational chart
plotter.
When under the satellite’s footprint,
Motivator
receives XM Radio programming and XM Weather data.
We exceeded XM’s range when we departed the
Bahamas.
Other cruisers with Sirus Radio
reported receiving signal into the Leeward Islands.
While the
Motivator
crew sorely misses XM Radio that is not the case with XM Weather.
For the cost, the service it is lacking at
best.
With Internet access there are
much better and cheaper weather products available.
At this point I need to mention the Internet.
I can’t imagine what cruising was like before
the Internet.
Cruisers use the Internet
for weather information, emails to friends and families, blogging, paying
bills, banking, business, working from the boat, voice communication (Skype),
and entertainment.
The list of uses goes
on and on.
When cruisers talk, you hear,
“Anchorage “X” is well protected, has good holding, and the Internet is great.”
Motivator’s
router is buried under the fly bridge console
The heart of
Motivator’s IT network
is a
Proxicast LAN-Cell
2 router.
It is overkill, but it
sure works well.
It provides a very
strong WiFi signal, can be configured for more than we will ever need, is very
secure, and is hardened to survive the harsh environment.
Motivator’s
client bridge mounted below the radar arch
Most cruisers have some sort of WiFi enhancer. Probably the most popular model is the Silver Bullet. Motivator
has been well served by a system supplied by Kennan
Systems. The Kennan system consists
of an external antenna connected to a client bridge that is powered by a Power
Over Ethernet (POE) injector that then connects to the ship’s router. Once in port or at anchor, the client bridge
is accessed through the router and the area is scanned for a suitable open WiFi.
When WiFi is not available,
Motivator’s
router is capable of switching over to an air card that allows us to connect to
the Internet via cell towers.
In the
States we were able to use a Verizon air card (more on Verizon later), but we
also carry an “open air card” that allows us to insert a
SIM card for
the telephone system we want to access.
This worked especially well in the Bahamas on the Bahamas
Telecommunications Corporation (BTC) phone system because about every island
had a BTC tower.
It would also work in
the Caribbean, however as we went down island, about every island had its own
system and we did not want to buy that many SIM cards.
Many cruisers use a Kindle to send and receive emails and surf the Internet
for weather and other information.
Once
out of the U.S., my Kindle couldn’t pick up a cell tower.
A little research revealed that I had a U.S. Wireless
only model (more about GSM and CMDA in the cell phone section).
So if you are planning to leave the U.S. with
your Kindle make sure you buy an Open 3G model.
OTA in Grenada
Fortunately, or unfortunately, depending how you look at it, living on a
boat does not mean giving up your TV.
Motivator came equipped with KVH TrackVision,
a satellite TV system that allowed us to receive Dish Network while in the
States and most of the Bahamas.
The
TrackVision system keeps the antenna aligned with the satellite while we are at
anchor.
At about the Turks & Caicos
we lost signal.
Other cruisers have been
able to buy a satellite box in Puerto Rico and with some equipment
modifications continue to satellite TV in the Caribbean, but it was not that
important to us.
Additionally,
Motivator is equipped with an
over-the-air (OTA) antenna that provides limited reception in some areas and
excellent HDTV in metropolitan areas in the States.
EPIRBs (emergency position-indicating radio beacons) and
PLBs
(personal locator beacons) are 406 MHz beacons which transmit digital
signals.
The beacons can be uniquely
identified almost instantly (via
GEOSAR), and a GPS position is encoded into the signal
provides instantaneous identification of the registered user and its
location.
Search and Rescue (SAR)
aircraft and ground search parties can home in on the distress signals from the
beacons and come to the aid of the concerned boat.
Motivator
carries a PLB pictured above.
The
difference between an EPIRB and a PLB is 48 hours battery time vs. 24 hours,
but the PLB is more portable so we can take it on long dinghy trips.
SPOT is the low cost
version of a EPIRB or PLB and uses its own satellites to receive distress
signals at which time SPOT notifies SAR.
Motivator uses SPOT as a
tracking device that reports our departure and arrival to our land based
trackers who have all of the necessary information for SAR.
Our SPOT is also linked to
Motivator’s web site so that others can
see our location.
The other satellite dome on the radar arch provides
Motivator with satellite phone and data service albeit at a very
hefty fee.
Phone calls are about $2.10 per
minute, and data is $4.00 per minute.
Therefore, we limit the number of satellite phone calls and have
a program to compress
outgoing and incoming emails.
Our usage
of the satellite phone does not justify the expense of the equipment and
standby charges, but we feel the safety aspect of having emergency instantaneous
worldwide communication capability
justifies the cost.
On the other end of the spectrum is our
Skype phone that has remarkably
low service charges.
The Skype service
is
Voice Over Internet Protocol
(VOIP), thus dependent on good Internet service.
To improve our Skype experience, we outfitted
Motivator with
Freetalk
Connect-Me, a small gizmo that connects between
Motivator’s router and a standard cordless phone to provide us with
service much like a landline in most homes.
When buying a Skype number, you are allowed to request an area code.
We selected an area code that would ensure our
family with landline service does not pay long distance charges.
Global System for Mobile Communications (
GSM) and Code Division
Multiple Access (
CDMA)
are two competing standards in cellular service CDMA is most commonly found in
North America and some parts of Asia, while GSM is found in the rest of the
world.
Some carriers do offer what is
referred to as an international or “open phone" that can work on both
standards.
U.S. phone companies, especially Verizon prefer to have you locked down to
their service, and under contract.
Only
about 4% of Verizon phones will work outside of the U.S.
Additionally, Verizon will suspend service
for only 3 months while you are out of the U.S. and the suspended time is
tacked on to the end of your contract.
The biggest mistake we made before leaving the U.S. was still being under
contract to Verizon.
Our “Freedom from Being
Owned byVerizon” party is on September 7, 2013.
The best way to go is have a truly open smart phone (not under contract to a
carrier) that will work on both GSM and CDMA and can be used as an Internet
hotspot when needed.
