An AIS receive-only capability would surely be nice to have to keep track of the on-coming tows.
Does CE have the functionality to easily distinguish tows from other vessels? So far as I have been able to figure out, Nobeltec TZT Professional (and the Furuno counterpart) does not. The best that can be done is to open a list of AIS contacts, sort that by vessel status, then "activate" those that are engaged in towing. And repeat periodically so that no one sneaks in on you.
