I have looked at the Stevens Institute sight for years after they did a current lecture for sailors a while back
Its really a bit to much information and requires a beefy data connection and computer to use onboard
The eldridge old as it is has GREAT drawings of LIS for every hour of the ebb and flood and I am not sure what people find lacking in it ?
Yup, that's what I've got to wonder, as well...
From the OP's initial post:
I'm thinking it would be handy to go to a website and pick a place and time and have a bunch of arrows with numbers showing the strength of the current.
That, of course, is pretty much PRECISELY
what those "Old School" tidal current diagrams are, as you've pointed out...
Only difference is, they're on a printed page you already have aboard, instead of somewhere out in cyberspace, that requires an internet connection to view.... (grin)
I've yet to find an easier method to figure the optimal passage for Delaware Bay, for example, than this diagram below... Too bad NOAA stopped including these in their publications a couple of decades ago, hopelessly Old School, I suppose...
I wonder how much my laminated copy might fetch on eBay, these days?
Yeah, I think I already know the answer to that one...
Hmmm, on the other hand, perhaps if I could somehow turn it into an app only viewable on an iPhone, or require an internet connection? (grin)
