Website with currents shown on chart with arrows

I'm looking for LIS

Old school was Eldridge.
I've got a hand held gps with currents.

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.

I can work it out of course with the noaa tables but it seems like it should be available.
I tried sailflow it and shows wind not current.
I tried weatherunderground again wind not current.

David, you've looked here already?

NOAA Tides and Currents - Home

PS: Wish we had something that sophisticated down here.

The Navionics app includes tidal currents.

deepzoom.com

It's my favorite current site on the web. If you are one of the 5% with a Windows Phone then there is also an app version of it called "Nautical Charts".

Navionics has the information, but it isn't presented as nicely. I don't understand why the deepzoom presentation isn't more common.

Re: Website with currents shown on chart with arrows

C-Map charts have current arrows and tide stations. I find the problem with a lot of this data is that it seems to be pretty inaccurate at times. The current info. can be 1+ hour off in certain spots. A lot of this info. in Eldridge and from NOAA has not been confirmed or updated in many years. The best info. seems to be from local sources or your own observations.

Stevens Institute shows info as you describe.
Believe it is just real time, as in what the current is doing right now.

It must be how we utilize the information. To me Nautical Charts is like a beginners version of Navionics. You can set ponts to received tide, current , wind speed and direction all on one screen in Navionics. All programs have most things you want. Not one has all unfortunately.

Nautical charts is nowhere near as user friendly as Navionics. Having used both. I found Nautical charts you had to keep returning back home to get to the next information you wanted. The other program I use is Blue Charts from Garmin as it presents some info better than Navionics also and has Active Captain.

It is easy to changed dates and times at the multitude of current or tide stations seamlessly which is important in long term planning. Especially on a tablet, I pad or Chartplotter. Navionics also can be used at home or below to plan and plot and on some chartplotters can be seamless bluetoothed onto the Chartplotter

Re: Website with currents shown on chart with arrows

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 ?

I just put my powerboat Lowrance unit back in the Cal 29 as it has NEMA 2000 fuel flow and i need a better idea about the A4s motoring range as were taking a long trip in late July

I have not motored enough BUT so far its between 4 NMG and 8 NMG as if you pick knots for speed it does all the distance in NM

The thing I had forgotten about was the level of current station integration the Lowrance natipath chip has as at ZOOM x it shows direction arrows with speed which is pretty cute

But for example going from Northport to Orient point on July 20th is freaking impossible unless you leave Northport at 2 am in foul current and the eldridge makes it pretty simple to see the flood is full on by 3PM at orient and hitting 4.4 knots
