6 of 1, half dozen the other. Find a couple freinds with offshore experience or do the ditch with help. If you go offshore, do it during a full moon and you can see most of the night. To do the ditch you need a good chartplotter and really good night vision. I believe you have to have better ability to see in the ditch than offshore. You have barges come around the bend out of nowhere in the ditch. You will learn alot either way.
