I go by within easy sight so you can see the name on my boat. I notice
that you're not underway, but you've still got your fishing gear out so
I figure you're intentionally drifting along- or that you would be
calling for help- so I just mind my own business and press on.
You'd really like to get my attention and ask for a tow, or some fuel,
or what not.......
What's my cell phone number?
If that is the case then who cares.....just get out the flare gun, the
distress flag and air horn to get your attention.
Regardless, you make a good point and every boater should have a VHF radio
on board. ;-)
