Re: Cruising Caribbean Single-handed
So when you lose your radar reception you still have the AIS data on your chart plotter? I can see where AIS would be important, particularly with those tankers and freighters that carry them. But, from what I've read and seen on sites like marintraffic.com not that many yachts carry AIS. The speed of the big ships makes them the most dangerous. So, I definitely will be getting an AIS transponder.
But, you're not using radar proximity alarm? Since most of the trips between islands south of St Martin are one day trips you don't see much need for alarms.
