Rob — Halifax Traffic most likely has a few very powerful open-array radars 
(like these: http://www.ipernity.com/doc/777361/41291844/in/keyword/76402/self 
<http://www.ipernity.com/doc/777361/41291844/in/keyword/76402/self>) that they 
use to track vessel traffic; these are going to far out-perform most radar sets 
located on the vessels themselves.  So no surprise that they can see you very 
well; but probably better than most of the vessels around you.  And the closer 
those large commercial vessels get to your boat, the greater the chance you’ll 
be in a radar shadow caused by the height of the vessel’s radar above the 
water, as well as the hull of the vessel itself.  So don’t count on them seeing 
you as well as Vessel Traffic does.
