Keep them reports coming.

Thanks.

As I understand it, type 9 messages are for SAR aircraft only, not ships. See http://gpsd.berlios.de/AIVDM.html#_type_9_standard_sar_aircraft_position_report
I would not expect rig stand-by vessels to be transmitting aircraft messages. In fact I think I've seen several rig stand-by vessels in Shiptrax on there way in and out of Invergordon. But even if there are ships transmitting type 9 messages, surely they are most likely to be in areas covered by other ships anyway. The problem with including SAR helicopters in the polar chart was that it quickly got distorted by returns from helicopters >60 miles away.

I didn't realise Airnav had started shipping ShipTrax to customers, so great to see some real users. Do you have anything specific about it being a bit clunky? Maybe there are suggestions to help make it less clunky for you.

Type 9 messages are all displayed in ShipTrax, they are only excluded from the polar chart. here's an example:
Maybe the Thames RNLI boats aren't AIS equipped?

Looks like you're correct, we only see "SAR" in the type box on both ships and aircraft so I wasn't aware they transmit different raw data packets.

In ShipTrax you'll also see the type as SAR. Here's an example from today:
