Raymarine AIS: Don't Buy It!

Raymarine released their AIS receiver about a year ago. There is a serious design flaw in it that makes it unusable in many situations. When any commercial vessel (with AIS) enters, then leaves the range of the Raymarine receiver, a major alarm comes up in the E or C series chart plotter, stating "AIS Connection Lost." This is the big loud alarm you get when you lose the GPS or press the MOB button. Since this occurs every couple minutes in a busy area, or every few seconds when a ship is in the fringe reception area, it keeps everybody awake on the boat. And unless you have a separete switch for the AIS, you can give up your anchor drag alarm when you're in an area with commercial vessels. The AIS alarms will keep you up all night long.

Raymarine's response: "We'll have a firmware update out sometime." They have no estimate as to when.

To quote someone more experienced than I, "If their brain was gasoline it wouldn't power a pissant's motorcycle around the inside of a Cheerio."
