[CA] [CA11] RealBathy

[danderer]

LH 3.9 introduced RealBathy. I tried it on my Axiom units this week. There are some things I don't understand.

The webpage at http://www.raymarine.com/multifunction-d...use3/v3-9/ says "Best of all, RealBathy requires no chart purchase or subscription."

The LH 3.9 Advanced Operation manual says "For tidal environments, ensure you have LightHouse NC2 cartography that includes tidestation information for your location."

In my testing it appears to record and display depth data but the function to set a Tidal Height Correction doesn't work. When prompted to select a tidal station from the list of available, the list is empty.

That suggests to me I don't have the proper cartography.

I do have the latest NOAA Vector-East Coast USA (3/31/2019). Is that different from NC2? Again from the web page: "Launching alongside LightHouse 3.9 Annapolis are Raymarine’s second generation LightHouse NC2 vector charts for North America."

So it isn't clear to me if I have NC2 or not, where to acquire NC2, and if there is a cost associated for it. Or if my issues is something entirely different.
