Maersk to pilot a battery system to improve power production
Looks like Maersk is trialing a 2 TEU (so forty foot container) battery pack for container ships to augment the house load generator for peaking and load leveling. Making it a container makes it easy to swap out too.

Interesting ship design, but the hydrogen production is rather energy intensive, limiting usability. Of note, they removed the VAWT's (and probably the traction kite sail) and have wingsails now, along with boosted solar PV cells.

Practical Application Limits of Fuel Cells and Batteries for Zero Emission Vessels
Uh, they only cover batteries or liquid/gaseous hydrogen PEM fuel cells in the comparison, so kinda incomplete. So no LNG fuel cells, no fuel cell/microturbine hybrids using the microturbine combustor as a topping cycle. Also, the basic conclusion is huge vessels could run a full trip, but on liquid hydrogen only, and short trip ferries should look at batteries instead.

High Speed Boat | Offshore Power Boat
Boat, based on waterski planing concepts to reduce drag. But isn't this actually just a planing wave piercing SWATH pontoon boat in principle though?

Transformis Inspire
Taking a cue from RV/camping trailer designs, this houseboat has a popout space underpinned by an expanding beam setup, so the pontoons sit wider after the interior space popouts deploy.

Wave Foil Developments
Basically wave glider parts mounted on the bow of a commercial ship. Sure, it probably works at reducing drag/increasing performance, but how would you deal with the draft increase? Retractable foil?

The Microtransat Challenge
Interesting that IMO/COLREGS treats these autonomous sailing boats as either debris, or oceanographic monitoring buoys if equipped with oceanographic sensors. US Coast Guard basically doesn't care as long as they're under 8 feet in length, though there is confusion over whether they are using a 4m or 2.4m ruling.

Kra Canal (Thailand) excavation by nuclear-powered dredges
Considering the current existence of the russian nuclear power barge, a nuclear dredger isn't wholly insane. But, considering it would be operating in foul water due to kicked up sediment, conventional sea cooling probably isn't available, limiting power generation ability. Doubt you want to use an air cooled reactor on a ship either...

The Ghost Ship | Project Icarus Workshop Update #3/4 | Icarus Interstellar
Like a car engine that runs off it's own supercharger (which makes starting a bit of an issue...), this starship propulsion concept uses waste neutron pulses from the pulsed fusion reaction to neutron pump a nuclear pumped laser which fires for the next ICF fusion pulse.
