Boat Forum / Cruising / June 2004Intra-coastal waterway navigation
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? Scott >Recently visited the Keys via boat.

I don't know where you were (on the Bay side I guess), but the entire ICW has red on the right going south and west and green on the right going north. When you go down a river on the ICW where the red would normally be on the left, the red will still be on your left, but the ICW markers have a yellow triangle or square on them, and the green marker on your right will have a yellow triangle on it. grandma Rosalie 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. Capt.

Does anyone know the logic behind >this or can tell me where I went wrong in my thinking? ============================================== In the ICW, red is on the mainland (continental US) side of the channel. Watch out for the transition points to conventional markings. red right rising is a better method > red right rising is a better method I appreciate everyone's response. I am still not getting it into my head properly. I know how it is and can navigate the ICW fine I am just wanting to understand the methodology. define rising... Also, in an earlier message someone said Seattle is your home in the ICW. I lived in CA and never saw an ICW. Thanks again for everyone's help. Scott The: East Coast; North to South, East to West. Gulf Coast; South to North, East to West. West Coast: South to North, West to East, i.e., clockwise around the country, are BROAD generalizations. Everyone can nitpick and say "well, whatabouthere?". Without a chart of the particular area, to see how the particular channel relates to those nearby, it's hard to give specifics. Another generalization: For channels beginning at sea, start at the most seaward buoy and it will be "RRR". For the Intracoastal, start in Maine, and as you head for Brownsville,Tx, it will be "RRR". Most importantly, forget these "generalizations", and check your chart, cause them "generalizations" can put your butt aground. otn >>red right rising is a better method > [quoted text clipped - 9 lines] > > Scott >Most importantly, forget these "generalizations", and check your chart, >cause them "generalizations" can put your butt aground. > >otn Trust me.... this is *great* advise.... your experience may have to do with intersection and collocation of navigable waters.

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.

Yellow triangles are on the inland side and yellow squares are on the sea side. Starboard only if going south from Nofolk. >symbols: Triangles indicate aids should be passed by keeping them on your >starboard side.

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. Len SignatureEliminate "ns" for email address. > > >The greens are between the sea and thee transiting the ICW.

"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." http://www.sailnet.com/collections/cruising/index.cfm?articleID=suelar0260 %20%20&coll_cat=Routing&Coll_name=Routing%20and%20Destinations Capt. Bill >>Subject: Re: Intra-coastal waterway navigation >>From: "Len Krauss" [quoted text clipped - 11 lines] >http://www.sailnet.com/collections/cruising/index.cfm?articleID=suelar0260 >%20%20&coll_cat=Routing&Coll_name=Routing%20and%20Destinations 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. grandma Rosalie 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. otn >>>Subject: Re: Intra-coastal waterway navigation >>>From: "Len Krauss" [quoted text clipped - 31 lines] > > grandma Rosalie |
