The greens are between the sea and thee transiting the ICW. Reds are inland
side. However, at channel intersections and, more importantly, where local
and ICW are one in the same, the local marks will usually take precedence,
but ICW marks may be there too. So, it can get confusing. There may also be
an ICW preferred and secondary channel. ICW aids have small yellow decal
symbols: Triangles indicate aids should be passed by keeping them on your
starboard side. Squares indicate aids should be passed by keeping them on
your port side. A yellow horizontal band provides no lateral information; it
just signifies that the aid marks the ICW.

Always consult a chart if you are transiting unfamiliar waters.

Recently visited the Keys via boat. While navigating the Intra-coastal
I notice that the green-red channel markers were backwards from all my
other boating experience(inland). Does anyone know the logic behind
this or can tell me where I went wrong in my thinking?

You were OK up to here. Yellow triangles are on the inland side and
yellow squares are on the sea side. Starboard only if going south
from Nofolk.

Hi grandma Rosalie -- always enjoy reading your posts. In this case, I
believe you've erred in your comment on mine.

You will find ICW yellow triangles on green square daymarks, buoys and
navaids with green lights. Similarly, you will yellow squares on red
triangular daymarks, buoys and navaids with with red lights.
This arises where ICW joins or crosses another waterway where that waterway
already had navaids in place when the ICW was constructed. Rather than add
more marks to identify the ICW, the yellow reflective decals were added to
existing navaids. Each such navaid thus serves a dual purpose.

The mariner transiting the ICW, and wishing to avoid possible confusion,
should be guided by the the yellow triangles and squares, and ignore the
colors and shapes of the navaids on which they appear.

C'mon now, admit your error.

Rosalie -- I misread your comment. You are right. Sorry about that. Anyway,
I think my further expanation might help the original poster.

Red-Right-Returning. In the ICW your home is Seattle.

I find it's easier for people to remember that red is always on the main land
side of the ICW going up and down the coast.

triangular daymarks, buoys and navaids with with red lights.

You might want to rethink that.

"A quick and easy way to determine which is the ICW, and which is not, is that
all ICW markers have reflective yellow triangles on the red markers and yellow
squares on the green markers."

What he was trying to say is that if the markers in question are river
or harbor markers, and not primarily ICW markers, then the red may be
on the ocean side instead of the land side of the boat. In that case
the red would have a yellow square on it.

For instance - going down (south) the Pungo River from the Alligator
Pungo canal, the red will be on your port where the green markers
would be for the ICW. So the red markers will have yellow squares and
the green markers will have yellow triangles.

That's also how you can tell if you've gotten off the ICW by mistake
as happened to us around Ponce inlet. Bob headed toward the
lighthouse, and missed the turn to go around the delta area. He
shortly noticed that not only were we not on the computer track, but
the ATONs didn't have the yellow ICW marks. I think we could have
gone through the way we were going, but we turned around and went
back.

One thing we always did before getting underway, each day, was to cut
up a number of pieces of masking tape to resemble pointers with a tab.
As we passed each buoy/marker we'd move the tape to the next expected
marker, placed, pointing to the direction we were to go to the next
buoy/marker, in line.
It tended to keep you on track and made you read and compare the numbers.
