Think for a minute about what's involved. -
Although it's a small boat, if I go down the ship channel to Galveston
(about 25 miles) I'm sharing the channel with lots of other boats,
including big ones and fast ones, going both directions, some passing
others, some fishing or trawling, some heading out to China, etc. Some
of them watch for boats like mine, and others are too busy or don't
seem
to give a damn. Some are skippered by pros and others are pleasure
boats
with semi-trained, possibly drunk red-necks at the helm (this is Texas
after all).

Gee, if I had all that to worry about I'd be on deck keeping a lookout.
By the way 25 mi is a long way to go in a MAC.
