Azteca

by CRN – Ferretti Group with Nuvolari & Lenard Naval Design

In September last year, Azteca was presented to the world at the Port Hercules quayside in Monaco at the 20th MYS – Monaco Yacht Show 2010. Azteca is the largest mega yacht launched to date by the shipyard CRN, and also one of the longest mega yachts ever built in Italy.

The yacht is all-Italian: produced by CRN, a top-level brand within the Ferretti Group, working with Nuvolari & Lenard Naval Design, which devised the concept design and created both the exterior and interior design. A complete portrait of Azteca is featured in the current issue (No. 19) of Yacht Première, presenting the yacht from its stunning exteriors to its amazing interiors.

The main dimensional and technical data
Bearing yard identification number CRN 124 and completely based on naval architecture and engineering produced in-house by the CRN Engineering Department, Azteca was built using high-resistance steel for the hull and light aluminium alloy for the superstructure.

The vessel meets the classification standards of Lloyd’s Register of Shipping (LRoS), Maltese Cross 100 A1, SSC, YACHT, MONO, G6, LMC, UMS and the requirements of the Maritime and Coastguard Agency (MCA) for the LY2 commercial code.
In terms of size, Azteca has a total length of 72.00 metres, equivalent to 236 feet
3 inches, a length at the waterline of 63.00 metres, equivalent to 206 feet 9 inches, and a total beam of 13.50 metres, equivalent to 44 feet 4 inches.
Under full load, the maximum draft of the hull is 3.50 metres, equivalent to 11 feet 6 inches, and the yacht’s displacement is 1,600 tonnes, equivalent to more than 3,532,000 pounds.
Azteca has a displacement hull with a bulbous bow and a longitudinal skeg in the
aft sections. The hull is equipped with two Schottel STT 110 tunnel bow thrusters, each powered by a 140-kW electric motor.
It also has a Naiad Vosper Marine Systems 820 stabilisation system, operational both at sea and at anchor, with stabilisers configured as two pairs of lateral fins positioned in the central sections, with an electro-hydraulically controlled drive system.
Azteca’s engine room contains two Caterpillar CAT 3516 B TTA CHD rating
V16 turbodiesel engines, each with a total cylinder capacity of 78.00 litres, equivalent to 4,766 cubic inches, and maximum power of 2,682 BHP, equivalent to 2,000 bkW, supplied at 1,600 rpm.
In terms of performance, under average load conditions, Azteca has a top speed of 16.5 knots and can maintain a cruising speed of 15 knots. At the economy cruising speed of 12 knots, the yacht has a range of 6,000 nautical miles, also partly thanks to the fuel tanks, which have a capacity of 250,000 litres, equivalent to more than 66,138 US gallons.

The freshwater tanks have a capacity of 40,000 litres, equivalent to more than
10,582 US gallons, supplied by a double desalination plant in which each unit produces 16,000 litres, equivalent to 4,232 US gallons per day.
Four tri-phase 50-Hz generators have been installed on board Azteca, based on Caterpillar 6-cylinder in-line diesel generator motors.
The two main generators are from the CAT C18 series, each with a cylinder capacity of 18.1 litres, equivalent to 1,106 cubic inches, and each producing 275 ekW / 344 kVA at 1,500 rpm.
The night generator is from the CAT C9 series, with a cylinder capacity of 8.8 litres, equivalent to 538 cubic inches, producing 175 ekW / 219 kVA at 1,500 rpm.
The emergency generator is from the CAT C4.4 series, with a cylinder capacity of
4.4 litres, equivalent to 269 cubic inches, producing 86 ekW / 107 kVA at 1,500 rpm. Azteca’s equipment includes a service and rescue tender, four jetskis / waverunners, a Riva Shuttle main tender, 9.25 metres / 30’5” in length, and a Castoldi Jet Tender 23 guest tender, 7.10 metres / 23’3” in length. For rapid transfers of the Owner and guests, Azteca also has a helipad platform with a carrying capacity sufficient to permit the use of a helicopter weighing 3,000 kg / 6,623 lb. [...]
