Are there any good underwater free topo maps online?

There are underwater topo maps on topozone but they aren't very good and they are not very easily interacted with. Maptech is good for the underwater topo of the ocean coast but aren't that good unless you buy the maps on cd. There are fair TVA maps at the Army Corps of Engineers site: http://www.lrn.usace.army.mil/opn/TNRiver/ and they are free.
 
Heres a quick snipI did from the navionics map for computer. I can get more detail if I want, just have to tweek the settings. </p>

Anyone know where this is?</p>

Where is it and are the maps the same as you get on the chips for gps. Minus the 3d on chips
 
Right before you go under the 58 bridge. (Wolftever) To the left. ...that last cove.

The maps are the same pretty much. I'd say they will only get better with upgrades and all. Its still pretty new but worth having.
