Thank you for adding AIS-Catcher to the plugin! Though I am still having issues with YAAC reading the messages. I have it set up through an External source port.
This is the error received from YAAC :
ExtMsgSrc unable to parse line !AIVDM,1,1,,B,ENkaSQLHh@@@@@@@@@@@@@@@@@@=;I<E<@lMh00003vP000,2*6E
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
Below is a screen shot of the port setup:

I guess my question is what is the proper way to import the messages from AIS-Catcher into YAAC? I may be doing this completely the wrong way...
Best Regards
