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
