I've never had a use for radar. When I've tried it it's about a 15 degree cone off the front of the boat, which is almost useless - like a spotlight. Even when I've known there's been a ship out there, it's never given me info that a hydrophone check couldn't. And I'm not big on cruising around the atlantic with a electromagnetic loudspeaker on. I do subscribe to active sonar, for lone merchants, or merchant-only convoys. A couple of pings beats fumbling around with the stadimeter and rec manual.
