i never go outside of the sight of land without some kind of tracker.
i have a tracker and PLB in the flatback, the fountain will be getting a tracker, PLB, and EPIRB.... we have 2 EPIRBS on the contender 36 i run. when 40-80 miles out, we want to make sure we have redundancy. the boat also has 2 vhf's. when things go south, they can go south quick...
