I went out on the boat yesterday about 3 nautical miles out there was a wavy line and on the inland side it looked like a cleaner blue and on the other side it was dark blue?

There’s a lot more stuff in the water when you’re closer to shore. That stuff reflects a lot of light, but places without it absorb almost all the light. So you’ll get a different color near the coast than you would in the open water.

So when its a different color abruptly, its because there is a point where the shallow area abruptly stops, and there’s a current that keeps the stuff in the coastal water from going out any farther.
