Fort Myers Beach has a good sized fleet of shrimpers which are
seasonally active. Here's one that's working about 10 miles off the coast tonight. http://www.marinetraffic.com/en/photos/of/ships/shipid:440169/#forward You can see their location, course and speed he http://marinetraffic.com Look for the orange "boat shape" a little west of Captiva Island and then click on it. |

That's pretty neat! I clicked on a ship in my area and it didn't show it's transit. What determines that being displayed? Also what determines whether a boat is actually displayed. Never mind, I found the FAQ. "Vessels appearing on the live map are equipped with an operational AIS transponder and they sail within the reception range of an AIS receiver installed on the land. " Mikek === Yes, the boat must have an operational AIS transponder and it needs to be within range of a land based gateway station that receives and uploads the data to the marinetraffic.com server. If you don't have a gateway station in your area you might want to think about becoming one. They will usually supply you with a free receiver/decoder and any old marine VHF antenna you have laying around will serve. |

As I write there are five cargo ships, 2 Navy boats and a pleasure craft within a few miles. I'll need to watch next time a tuna boat or shrimp boat goes out and see if the have the AIS device.

Mikek I am going to replace my VHF with an AIS unit this year. Just have to decide which one. May have to replace my GPS/sonar as it is a Lowrance HDS gen 1 and only one output for GPS data. I do not think I can overlay AIS on the GPS. |
