I have a 10" Android tablet and I found this app. There was another one i was looking at as well but I forget the name.
I am going to download and give that a try.
I do have a standalone land GPS to use as backup.
I also found some PDF's of charts of a reduced scale NOAA charts. It's 21 pages and I am going to print out the areas I need.
I just found online the wooden boat show. It looks pretty cool, I may have to check it out.
