Radar does use a fair amout of power. That's a fact but not
necessarily an issue on a larger boat with decent battery banks.
Modern radars do have power saving modes where they wake up every
minute or so, make a few sweeps, activate an alarm if targets are
detected, and then go back to sleep.

I've sailed thousands of miles
at night without radar but I count myself lucky and will never do it
again if I have a choice.

Radar sunk the Andrea Doria. The 3rd officer on the Stockholm misread
his.


Then the 3rd Officer on the Stockholm sank the Andrea Doria, not the
RADAR.
