Get the navionics map card and be sure to UPDATE it monthly. The updates are FREE for one year. The data is really good but the updates can save you a TON of trouble. Navionics is THE best mapping and the web application on your I pad or Android is fantastic. Questions www.navionics.com or call them.
I'd be curious to know how often they are truly updating the mapping on West Point. I don't trust a single mapping company on the river above 219. I run it multiple times a week and I know how often it changes.
