A151-foot motor yacht designed to celebrate the timeless values of classic style, while at the same time boasting the last word in sophisticated technology. A modern, functional motor yacht, but above all one that positively exudes beauty: starting with her elegant exterior, and her clean, fluid styling.
American yard Delta Yachts is currently working on a number of yachts under construction at its modern facilities: these include a 156-foot craft in composite material, code number 156039, expected to launch this year; and a 200-foot yacht in steel and composite, with code number 200040, set to launch next year. These will join the Seattle shipyard’s latest creations. After Slojo, the third 156-foot motor yacht built using Delta’s proven semi-displacement hull design, presented last year in issue 13 of Yacht Premire, we now present Katya, the fifth motor yacht built using Delta’s proven full displacement hull design. Delivered to her Owner ahead of schedule last June, Katya’s maiden voyage last summer in the Pacific took her southwards through the Panama Canal. She then headed to Florida, where she was displayed by Delta in the 50th Fort Lauderdale International Boat Show (2009). This was followed by busy charter season in the Caribbean. This coming summer she will be in the Mediterranean.
The main dimensional and technical data
The new Katya motor yacht (construction code 151037) is based on a naval architecture and engineering package developed entirely in-house by the Delta Design Group’s expert team. Built in composite at the Delta Marine facilities, Katya is Lloyd’s Register, Maltese Cross 100 A1 SSC Yacht Mono G6 MCH compliant, as well as MCA compliant. Now for her dimensions: Katya has a LOA of 151 feet (more than 46 metres), with a length at waterline of 134′ 5″ (nearly 41 metres). Her total beam measures 31’8″, just over 9.65 metres, while she has a moulded beam of 30′ 8″ (nearly 9.35 metres). The yacht’s draught when half loaded is 9’2″, or nearly 2.8 metres, while she displaces 451 long tons. The yacht’s Gross Tonnage is 472 ITC. She has a displacing hull fitted with a Quantum QT-150 150 hp bowthruster, in addition to a Quantum stabilizer system (Zero Speed, QC-1800 series), with two lateral fins and an integrated central hydraulic system. Katya’s engine room is fitted with twin V8 C rated CAT3508B turbodiesel marine engines, each with displacement of 34.5 litres (2105 cc), with a maximum output of 1000 bhp (equivalent to 746 bkW) supplied at 1600 rpm. As for her performance, Katya can achieve a top speed of 15.5 knots and maintain a cruising speed of 12.5 knots. Fuel tanks that can hold up to 20780 US gallons (78,661 litres) of fuel mean that when cruising at 12 knots, Katya has a range of more than 5 thousand nautical miles. Her freshwater tanks can carry 3000 US gallons (11,356 litres) and are constantly topped up by a watermaker system by Sea Recover, which supplies 3600 US gallons a day (13,608 litres). [...]
