Testing AIS identifier

We along with a few others have been asked to test a new battery operated Automatic Identification System (AIS) transmitter.

The unit is battery operated and should last for up to three days sending out our position. This is solely a transmitter so we do not gain info back. This means our boats will be visible to anyone with an AIS receiver or via the internet.

The unit clamps onto the bracket which will be fixed to highest and clearest point of boat and is taken off to recharge or recharged aboard.

This unit is not currently available for sale but the manufacturers have had such good response from users about this that their designers may start to build a unit for sale in the EU.

The unit is programmed for a specific boat with MMSI and call sign and boat name.

What are peoples thoughts on such kit? Unit is shown in image in a base charger and has a clamp for the boat infront. The clamp is being adjusted for the top of AFrame

Depends on the cost I suppose. Concept is a good idea if operating in busy shipping areas

I believe the seame powered full units are about 600 and plus fitting, discussions suggest maybe 200. but dont hold me to that

It sounds like half a good idea, personally one of the main attractions of AIS, is being able to see other vessels & their details.

I think when you can buy a fully blown transceiver for 400 then it would have to be sub 150 to be worth it's limitations. As PD said, being seen is just as important as being able to see.

Ditto
Will this unit just contribute additional AIS "noise" which desensitizes actual AIS receivers to its value? All the while getting no information for the actual noise generator.

Yep agree that if you want full info this is no good. When we trained recently on radar reflectors we discovered the best passive radar reflectors from Tri Lens were about 250 and were not up to the required visibilty for radar, whereas this offers a signal to be collected by AIS receivers and additionally we can look at where our boats are, it give info on speed, direction as well.
Using website we could set up outer limits and be e mailed if the boat went outside an area whilst on charter, (Ok you can remove the unit).

The triangle button on the unit will eventually become a mayday beacon but not setup yet during trials
