Very good - I'm surprised CM didn't know this because its rather fundamental. Basically,
features will be wider on the screen by the beam width. "Inside" features, such as a cove
or entrance that are smaller than the beam width will disappear. Buoys that are closer
together than the beam width will merge. As you point out, RB wouldn't see the entrance
at Port Jeff until he's within a mile.

This is the real reason to get larger antennas, which have a smaller beam width.

BTW, where did you get your numbers? They correspond to statute miles. We use nautical
miles here, not baby miles.


Blame it on a trawler website:
