doesn't show depth of water, for instance. In other words those sailors
attempting to use radar properly do so at the peril of disregarding all the
other important aspects of sailing. Radar needs a dedicated radar operator.

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.

You can get radar under a grand, and with a power consumption of less
than 2 amps. A hundred amp alternator can put out a days worth of
juice in fifteen minutes. You would need a hefty battery to absorb it
that quick, however.

Wilbur hasn't yet figured out how to fit a 100 amp alternator to his
outboard motor.

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.

If he hadn't had it he wouldn't have misread it.
