“Just driving up to it in the boat and seeing it there in the water, really having swam 9,000 miles, was pretty amazing,” recalled Hine, the senior vice president of operations for California-based Liquid Robotics, Inc.

“The exciting part is not making it to Australia but the journey in between,”

The wave gliders resemble over-sized Boogie Boards with racks of fins submerge below the surface.

The waves catch the fins to propel the vessel forward, indefinitely.

COLLISION: BALTIC ACE & CORVUS J

 

Wednesday 5 December (2012); around 19.20 local time vehicle carrier Baltic Ace (IMO: 9386213, Port of Registry: Nassau, Bahama’s) and containership (IMO: 9262895, Port of Registry: Limassol, Cyprus) came into collision with each other about 35 miles off the Dutch coast in the North Sea near the North Hinder Light Buoy.

The  Baltic Ace is a roro, roll on / roll off.  Internal structure of the roro is open. There are no separate compartments.

The Baltic ace sank in 15 minutes.  Human lives were lost.

 

I guess, a roro is probably not the best choice for seasteading.
