Garmin GPSmap Cautions

[rbmitchell]

I have sung the praises of Garmin for 20 years, ever since they were ProNav, but ran into serious problems running the east coast Intra Coastal Waterway recently. Coming north, entering the Wynyah Bay, NC, the ICW disappears from the chart. Not until you get into Snows Cut, 5 or 10 miles north, does it reappear. If you did not have other references on board, you would be lost. While this was not the only "missing link", it was the only one where the ATONs are far enough apart that you could not navigate by seeing the ICW marks on the large assortment of inlet bouys.

This problem was not only on the 740s but also on the 6212 I bought after I saw how great the daylight readability was on the "little" 740.

I will bring the feed from the computer below decks running Maptech onto the 6212 display using the Garmin internal charts as backup.

You have been so advised.

Sounds like a reason to be in touch with Garmin.

that's why i always have my laptop as a back up!! and the ICW chart book...

i think you meant entering Cape Fear River, Winyah bay is about 100NM from Snows Cut

I had to go look. You're absolutely correct. From the ICW at Southport to Snows Cut you're on your own. While there's also a piece missing in Winyah Bay its nothing like navigating the Fear River.

Thanks Pascal.

i agree, it's easy to miss that turn off the river... actually both into the Waccamaw from Wyniah bay, and into Snows Cut from cape fear.

especially since, if i remember correctly, in both cases being RRR the reds are reversed.

I guess the issue is with the plotter putting the more detailed chart over the ICW chart...

Chartbook and a good pair of binoculars pretty much take care of it. If you are that dependent on electronics, might be time for a Power Squadron refresher class. Regardless, if you are passing by Morehead City, let us know. Complimentary adult beverages served every evening on the aft deck Savoy Lounge. Saturday is the last day of the Big Rock Blue marlin tournament. Lots of quality boat porn at the docks here and in Beaufort.

Better yet, come out to Cape Lookout where we hang out on the hook almost every weekend.
