I was on another forum and seen where someone had ran into a sunken ship in Conway bayou off the ICW by Sabine Lake and it caught my attention. Please be away of your surroundings and if you are going into a new area research the area some and try to get a good idea of where you plan on running and any hazards that might be in the area. As you can see in the screen shot it has the sunken ships and barges marked.

The water is dangerous whether ya know the area or not. Wear ya PFD's take ya time and be very careful is the best advice. Lost a dear friend born and raised here and knew the local bayou like the back his hand. While looking for a lost deer dog he hit a sunk floater it veered him to hit the bank fly outa da boat face plant into the mud while being knocked unconscious and smothered. Just typing this teared me up. The man knew the water and always wore a PFD and was very safety conscious.

There are plenty of free resources available online that you can cross check against. You can use the NOAA chart viewer or any of several available websites to cross check.
This online chart viewer clearly shows several obstructions and wrecks like the screenshot.

I would also recommend cross checking against the official NOAA viewer when planning.

Also make sure that the person navigating does not get intoxicated. There was a boat accident last year in Florida in which a baseball player lost his life.
