GPS with AIS transponder for small boats and blue water sailor
Small boats and blue
sailor have one thing in common a small budget they
operate on and a high desire to increase the safety while under way.
Both a hard to overcome as space is limited and the available resources need to provide the biggest return / safety.
Dez. 2014 USCG AIS rules changed
With the AIS B system aimed at lighter commercial and leisure markets new products reach the market like the GPA-33
But with the AIS B system
aimed at lighter commercial and leisure markets new products reach
the market like the GPA-33
The GPA-33 is a 4.3" color LCD display AIS B transponder combo with GPS navigator in a small form factor like the Furuno GP-33 GPS it can be top mounted or flush mounted.
With a price of approximately 500,- per unit it should allow small budget sailors to equip their vessel.
You might ask how we can benefit from it and for that we need to understand the AIS system
(or Automatic Identification System A or B ) is a international
transponder system for ships intending to increase the safety at sea
It operates in the VHF band. The two frequencies used worldwide are 161.975 and 162.025 MHz (channels 87B and 88B, or AIS1 and AIS2). The signal is transmitted via external VHF antenna and has the reach of normal VHF signal in line of sight.
An AIS transmitter regularly transmits the ship's position, heading, speed and MMSI (the unique maritime identification number). This data is received by ships in the vicinity or land stations.
Till recently AIS equipment was cost-prohibitive for smaller vessels and did not reach its recognition but was in service for the big commercial fleet.
the recent addition of
AIS devices designed to be fitted
to a life-jacket and assist in Man Overboard recovery it adds another
safety level to the crew on a vessel under way.
Lets admit that in case you fall overboard the nearest rescue possibility is the vessel you fell of ...as time passes the distance to this vessel increases and the chances of MOB recovery decreases in the same amount.
You most likely don’t fall overboard in
conditions but your chances are higher in a bit rough conditions
where the line of sight is limited ..
The small PFD with strobe only pops out of the swell from time to time. The AIS signal would give a precise location on the vessels display at time of signal and CoG to make a interception of the MOB easier.
sailors will desire to have one or the other kind of GPS on board for
position fix and ground made good.
If the same unit offers a AIS without increasing the units expenses to much you will get the benefits of both without additional hardware ...the GPA33A does just that.
This covers your personal gain in a short!
Add that the AIS would
allow a slower maneuvering vessel to find the space in the commercial
shipping lane to sail through without getting in the situation to
count the rivets on the bow of a commercial freighter who does not
even realize you are there ...
If you have your AIS unit turned on to send signal ...he most likely is aware of you.
and leaving some ports where recreational and commercial traffic meet
in the same shipping lane due to spoil areas on both sides of them
will be easier with AIS.
Especially under limited visibility as well as identifying vessels approaching in your path and contacting them with their unique MMSI....
If your vessle is used for recreation only, is not
required by law to carry a radio and does not make international
voyages or communications ..
Than you can request your MMSI through BoatUS for the United States of America
But if you exceed these limitations than you are
legally required to obtain a Ship Station License from the FCC.They will issue an appropriate MMSI
with the License.
