Sectional/ Terminal Chart Question

Wed Mar 08, 2006 2:44 pm

On the Seattle Sectional/Terminal charts water is depicted in dark blue and light blue. In some cases the distinction between the two is right in the middle of the waterway (ie the same 'body' of water is one half dark blue, one half light blue). The aeronautical chart users guide says this distinction is to distinguish between OPEN water and INLAND water.

My questions...
How can the same body of water be both open water and inland water? How is the distinction determined?
Why do we care Open vs Inland..ie Why is there a distinction made between the two? Is there an official FAA source that talks about this?

Can you show an example?

There is a distinction between inland waters and international waters in terms of which rules of the roads apply for maritime shipping. The rules that apply for shipping also apply for seaplanes.

There is a legal line of demarcation that defines the difference between international and inland waters it's in a Coast Guard regulation.

for example in San Diego, a line between Point Loma and Zuniga cuts San Diego harbor. on one side it's inland waters, the other side international waters.

I have a jpg. What is the site everyone here to post their pictures to? The one that shows a frog when the bandwidth gets exceeded. When I figure out how to do it, I will post it here.

In the meantime, if you go to www.aeroplanner.com and go to TIW (Tacoma Narrows) on the VFR chart section, you can see the color difference in the surrounding water.
