Delta Marine Industries (Seattle, Wash., USA) has announced the delivery of its newest 66m/217-ft yacht, Invictus. It features a 13.1m/43-ft beam and high ceilings and spacious rooms emphasized by floor-to-ceiling hull-side windows.

Diane Johnson of Diane Johnson Design, working with Johnson, Wen, Mulder Architecture, designed the yacht's interiors and features. The Delta Design Group, responsible for the naval architecture and exterior styling, designed an ice-strengthened steel hull with composite superstructure. Using finite element analysis and its own advanced engineering, Delta says it incorporated composite materials, steel and aluminum into the construction allowing the best material to be chosen for each application. This combination is said to have enabled the designers to achieve the high ceilings and expansive windows that the owners’ desired.

Powered by twin Caterpillar 3516 main engines and carrying more than 50,000 gal/189,270 liters of fuel, the yacht has a 6,000 nautical mile range at 12 knots and a maximum speed of 17 knots.
