Damn right keep the radar...it's great and I'd like to have it...it'll show you the approaching tanker...but take it easy anyway, cuz there are things afloat out there the radar will never see...containers fall off ships all the time and float w/only inches showing above the water...we saw a barge full of scrap-metal adrift off Charleston the radar didn't pick up...the best electronics on the planet can't compensate for SIGHT...
