When all the buoys, islands, drunken stinkpotters, etv have AIS, then maybe.
I can say that in an unfamiliar area, RADAR is an absolute essential navigational AID, just like GPS, charts, binoculars, and a rested and sober mind.
I got an Old Fat Boat
She's Slow But Handsome
Hard In The Chine, but Soft In The Transom
I Love Her Well, And She Must Love Me
But I think It's Only For My Money
