Hope this helps a bit.UBC site.

What speed will the boat be going after 30 s?
a = v/t therefore v = at = (0.04m/s2)(30s) = 0.0012 m/s = 1.2 mm/s

I must admit that I find this difficult to rationalize. If this were to be economical when used as a commercial ferry propulsion system, then the military would likely have been using this for years. Given the power available through a nuclear reactor, it'd be a no-brainer!
Could the ferry have been using a ducted pumpjet? To the external observer, they both 'push' water.
