A great deal of research related to student learning styles has emerged in recent years. Through that research strong arguments have been made that more kinesthetic learning methods, such as hands-on or experiential learning, are more effective than more traditional methods like the lecture. In the maritime field, technology such as simulation, has provided us with tools to harness the power of experiential learning; however, those tools alone cannot ensure students are learning…

The privately owned U.S.-flag foreign trading fleet, which is an essential component of U.S. sealift capability, stands on the edge of a precipice. The fleet – roughly stable in terms of cargo carrying capacity from 2000 to 2012 – has declined from 106 vessels in 2012 to 78 vessels at October 30, 2016 primarily because of a substantial decline in available U.S. Government-reserved cargo.

Charging stations were even placed along the river so these electric launches could continue up and down unhindered. An article in Scientific American…
