C-Map’s hyper harbor detail, & more charting/POI news
Testing Nobeltec Admiral 11 is going pretty well, and I’ll write about it soon, but what really got me grinning is the latest C-Map Max Pro chart of Camden Harbor that came along with the trial software. I’m a long time fan of C-Map’s C-Marina concept — in which cooperating marinas are charted in super high resolution — but in actuality C-Map’s earlier attempts at Wayfarer Marine detail were seriously flawed. Well, not only is Wayfarer now exceptionally well depicted (with one major exception), but other improvements make C-Map’s the best visual guide to my harbor’s complexities yet created, I think. Please click on the image above for a full screen window as I explain…
As anyone familiar with Camden Harbor can tell you, C-Map now has Wayfarer’s main docks accurate nearly to the individual ramp and float level and, most striking, they’ve charted all 32 of the private two-boat inner harbor mooring floats. They even put the slight skew in Gizmo’s home float that you can see on a typical satellite photo map, which is probably where they got the information (incidentally, an adjustment to the northern mooring stone took the skew out last spring, but the sat photos haven’t nearly caught up yet). While some critical harbor businesses like Willey Wharf are still mislocated — which I’ve corrected with yellow markers (head’s up, C-Map cartographers 😉 — this is still the best Inner Harbor chart I’ve ever seen. And while I may be obsessive about Camden detail, it does matter.
In fact, that route I created in Admiral 11 is exactly the path some visiting yachts as big as 100 feet take before backing into the Public Landing, and that’s got to be a hairy proposition for a skipper who’s never seen the harbor before (and can’t see beans from outside). And look at how beautifully C-Map charted the private aids we use to mark the channel between the two Outer Harbor mooring fields! That’s exactly what they look like — 5 mph speed pylons with a series of un-numbered red and green lateral ball buoys — and a far cry from the way NOAA charted those aids. Could it be that C-Map was reading my Panbo rants about NOAA’s work? Well, the 7/28/2010 Issue date associated with some of this “non-official port/marina” data” does correspond.
That massive chart portfolio would have only cost $35 if I hadn’t had a voucher, and apparently anyone who has a recent chart card covering that area will have free access to the PC app for planning purposes. I think the app — maybe along with a Navionics card reader — may also be the eventual gateway to getting data updates on the card. I wish Navionics had clear information on their site about what’s happening, and specifically how the whole PC App download process works, but I can tell you that it went well for me on a Vista 64 bit machine (and it’s supposed to be Mac compatible too). Click and gander (and perhaps enjoy as I did retracing my March, 1974, cruise north from Cap Haitien, which had NO nav aids then):
on of Camden Harbor chart 13307 has had the channel buoy mess corrected, even though they were updated recently. Sigh. If you look on the zoomed-in ENC at lower right below, though, you’ll see the Wayfarer marina docks that aren’t on the Google sat map yet and that C-Map missed (no cartographer has yet adjusted for the massive dredging). Note also the difference between Northeast Point at upper right on the ENC compared to the traditional shore line seen on the 13307 raster in the window above it. I tried hard to get NOAA to reverse that decision, but damned if the new 1:40,000 scale raster (upper left) doesn’t also have the point as an island. It’s certainly not a critical detail, but one day we will have to discuss how NOAA came to that faulty conclusion.
