Exuma Tide Info--Confusion

[rdbaa1286]

Ok---I have searched far and wide and still am confused.

Chartering power catamaran May-June 2018 from Nassau to G'town.

I've found somewhat reliable tide tables for Nassau....and the different sources I'm checking largely agree.

But as we travel down the Exumas, I'm having trouble finding tide table sources that agree for southern Exumas....specifically Steventon and/ or Georgetown.

I cannot find sources that agree and here's what I'm checking:

Navionincs App
Garmin App
NOAA
Worldwide Tides and Currents Predictor
Exuma May 2018 Tide Table

For the life of me I can't get the above to agree.

Any advice would be appreciated!!! As all of you know the weather, currents and swell in Exumas can make or break a day. (Sorry if this is covered in an earlier post).
