Holland America's 86,000-ton Nieuw Amsterdam is being constructed in an interesting way. The forward portion of the hull was constructed at Fincantieri's Sestri yard near Genoa (Italy). The rest of the ship is being put together at the builder's Marghera yard near Venice. Just prior to the construction beginning at Marghera, the bow was floated and towed all the way around Italy to Marghera where it was joined to the rest of the ship.
