None of that information is non-public (you can find cargo ship data online for free), none of it is particularly valuable (you are looking for information, it is hard to know how much information is in cargo ship movement...it depends), and most non-quant hedge funds have been doing stuff like this for decades (i.e. hiring people to stand outside a retailer's stores and count customers)...most of this stuff is less useful than people think (again, you need information, data with intent).

Also, most of this stuff isn't in the price. Lots of people are collecting new data, it is definitely becoming more widespread but the actual synthesis is tricky (most people who are quants do not understand fundamentals, and most fundamental analysis don't understand data...most firms are swirling in a perfect storm of ignorance).
