Royal Caribbean will go forward with building another Genesis ship, as the company exercised its option on Monday. Like its sister ship, the 5,400-guest, 220,000-ton ship will be built at Aker Yards in Finland, with delivery expected by August 2010. The first Genesis-class ship, priced at over $1 billion, is due in fall 2009. RCL estimates that the second Genesis ship, and 24th in the company's fleet, will cost approximately $260,000 per berth, which is around the same price as the first Genesis ship.
