Nissan's City of St. Petersburg; an eco-friendly car transport ship http://green.autoblog.com/2011/01/03/vi ... leaf-ship/ Other than tonnage, I can't find any dimension data. |

Very interesting concept behind the rounded prow, looks very retro/popular science |

Especially when you consider just how little impact air friction have at those speeds. |

Exactly, maybe for a fast ship with a exceptionally large superstructure but that's a very small minority which could use it to some effect |

Hm! perhaps fuel savin? The new car carrier is distinguished by its unusual appearance, especially in fore part, where the cargo hold superstructure is shape-integrated with ship's bridge and bow (fore) part of the hull constituting a semi-sphere. Owing to this aerodynamic design, the ship achieves a reduction of wind resistance of up to 50% compared to conventional vessels. Based on calculations of an annual navigation rate of 75% under average hydrographic conditions for the North Atlantic Ocean, this new design can lead to fuel reduction up to 800 tons annually, which converts to achieving an annual reduction of approximately 2,500 tons of CO2 emissions.

So they save $300.000 a year? How much did cargo space did they loose in doing it? |

You do not lose the capacity. they just take a ordinary design and make it a bit rounder.it is like to compare the Volvo 740 and Volvo C70! everything is written in the article. Outline of the energy saving car carrier - City of St. Petersburg: launched - 11.09.2010 delivered - 22.12.2010 builder - Kyokuyo Zosen K.K., Chofu, Japonia operator and ship manager - Nissan Motor Car Carrier, Japonia flag - Panama LOA - 139.98 m LBP - 131.00 m B - 22.40 m H - 24.45 m T - 6.50 m GT - 21 143 deadweight - 5000 t capacity - 2000 standard cars decks: 8, including one hoistable main propulsion power - 12 000 kW (16 316 KM) service speed - 16,9 / 18.50 knots max speed - 21.22 knots |

And by rounding it they've decreased it internal volume compared to a conventional design with the same dimensions. |

so to get the same capacity as one ship they have to build 2 and because off that there will be more pollution by just produce them: Production of steel, iron and aluminum. production of engines. production of the batteries. production of all the electrical parts and radars. paint. propels. ... shall I continue! Thus it become twice as much pollution to build that ship because you have to build two vessels to get the same capacity as one vessel! (Top Gear logic!)
