But I want my Chesapeake friends to see this water. Remember, a lot of this is visual navigation through depths. As the saying goes:
"Water that's blue is deep and true;
As it shades to green, the water gets lean;
White or yellow will ground a fellow;
If the water is brown, you'll run hard aground;
If the water is black, you better tack."
This is a shallow passage we've taken a number of times. It's much better than going out to the ocean side in swells, but can only be done with a shallow draft boat (unless it's flat calm, like last year when I led a Monk trawler through safely).
The water got VERY skinny at times between the rollers. The depth sounder couldn't even get a reading, but I could sure see the sand below. And then came the breakers.
See how close that sand bottom was? Yikes! It's a good thing we've got a shallow-draft boat.
And here's a movie of it:
