Gee.  Exactly what's needed..  You could lower the bed enough to put a 'hot-tub' in there.

Great video Dave! Looks very simple, light and compact but will need a supercharger (and a turbo to get the efficiency) like our 2 cycle Detroits. Fairbanks-Morse has been making a common combustion chamber 2 cycle since the 1930's but used 2 crankshafts. Most of the U.S. submarines in WWII used this 2 cycle engine. The others used a GM diesel much like our 6V-92TAs. Here is an excellent site for diesel fans with a nice cutaway diagram: Tugboat Enthusiasts Society

Mexico John Haygarth worked on a high horsepower, multi crankshaft 2 cycle design and should be helping this guy!

Here is the world's most powerful and most fuel efficient engine. A huge 2 cycle with the crankshaft alone weighing 300 tons. They don't use a supercharger but use electric fans to start it until the big turbos take over. The guy in the video was talking over 40 percent efficiency but this big fellow breaks 50% fuel efficiency. Check the size of the workers compared to the engine parts.

Indeed...These bad boys burn "Bunkers" for fuel.  In another life I used to do the ships chandlering for a couple of banana companies which use very large vessels to transport fruit from the tropics to the EU, NA, and the Orient.

Pierce,
When I worked for the local Cat Dist, (Virginia Diesel), had to do little control work on a pair of Cat 399 engines, 1200 RPM max, about 1500 hp ea.  Found I did not enjoy tug boat work, then had to do about the same with a pair of DDC 16V-149 engines, always loved the sound of the DDC engines, still hated tug boats.
WW2 subs used the 12 or 16-278A inline GM/Detroits, have seen then on two subs as museums. were inverted, crank on top, cylinders below, weird setup.

Perhaps a little off subject but a good read this late winter (half empty) or early spring (half full) is the story of the salvage tug, the Foundation Franklin. Hard to put down once you start. See at: The Grey Seas Under: The Perilous Rescue Mission of a N.A. Salvage Tug by Farley or The Grey Seas Under: The Perilous Rescue Mission of a N.A. Salvage Tug: Farley
