And if those seem like big numbers, wait until you hear how many dollars it'll take to construct it: $8 billion, according to designers Lazzarini.If funded and built, the sea turtle-shaped "terayacht" would be the largest floating structure ever built, spanning 1,800 feet long and 2,000 feet wide. Dubbed a “floating city,” the boat would feature hotels, shopping malls, parks, and ports for smaller vessels and aircraft to connect.  Due to its size, the yacht would require the construction of a special dam that would flood to levitate it before being launched. The designers have noted Saudi Arabia’s King Abdullah Port as a potential building location. The shipyard would stretch approximately 2,133 feet wide and 1,969 feet long.  The yacht’s hull would be comprised of 30,000 "cells," and its draft would stretch 98 feet. It would be capable of moving at a speed of five knots. The boat’s “arms” would draw energy from the drag and waves that break against it. Rooftop solar panels would also provide power.
