2 mins read

A new catamaran concept called “Decadence” designed by Andy Waugh stands out for its ultramodern appearance. Inspiration for this 80-meter-long and 30-meter-wide yacht comes from the visual elements and technological advancements of 1920s car and airplane designs.

The Decadence features a unique hull design known as SWATH (small waterplane area twin hull), which consists of a submerged, teardrop-shaped hull attached to a central body. Providing a more comfortable and safer cruising experience, this design enhances stability and reduces the rocking and rolling motion typically experienced by regular yachts.


Allowing for innovative interior layouts and space, this SWATH hull form of the Decadence catamaran offers various advantages. The owner’s suite, for instance, can be exceptionally spacious, measuring 20 meters long and 3 meters high.

The decks of the yacht also feature enclosed areas that provide privacy and protection from the weather. Maximizing the available space in the main body for guests, the crew areas and technical spaces are situated in the submerged hulls.


The cylindrical hulls additionally conceal inflatable wing sails that can be deployed to optimize the catamaran’s lift-to-drag ratio. When it comes to harboring in ports, the wide size of the Decadence catamaran can present challenges, despite its spacious dimensions.


Andy Waugh, however, has addressed this concern by Emphasizing the yacht’s enhanced stability, reducing the need to seek shelter during adverse weather conditions. The yacht can maintain its balance while experiencing some wobbling, preventing it from sinking deep into the water.


Space is incorporated for two 14-meter chase boat tenders in the Decadence catamaran, which can be deployed as luxury shuttles to shore. Various features are offered by these tenders, such as open decks or fully enclosed cabins, providing greater comfort and capacity compared to regular limo tenders.

In order to achieve a 30% reduction in energy consumption, resulting in fewer refueling requirements. Andy Waugh intends to implement a new propulsion system on the Decadence yacht, coupled with its sleek cylindrical hulls.

Several technical advancements are boasted by the futuristic hull design of the Decadence catamaran, such as an estimated 70% reduction in pitch and roll movements compared to conventional monohull superyachts. This significantly enhances comfort and safety for those on board.


The interior space of the yacht spans a vast area with a 30-meter beam, allowing for the possibility of an expensive owner’s suite.Providing additional privacy and protection from the elements, each deck is equipped with fully enclosable exterior areas. The Yacht Design of Andy Waugh acknowledges that the Decadence yacht’s oversized beam may present challenges when finding suitable marina berths.


They, however, have implemented solutions to address this issue. The need for shelter from adverse weather conditions is reduced by the increased stability of the hull form.

Additionally, the yacht is designed with capacity for two 14-meter chase-boat tenders, which can serve as transfer shuttles to shore. Indicating the potential utilization of wind power, renderings of the Decadence yacht also showcase retractable inflatable sails.


The design studio, furthermore, mentions a “radical new propulsion system” expected to reduce energy consumption by 30%. The Yacht Design of Andy Waugh is known for pushing boundaries with their yacht concepts, including previous projects such as the 70-meter Serafina, 175-meter Acionna, 45-meter Revolution, and 90-meter Nouveau.


Currently, they are working on a new 100-meter plus project commissioned by an American tech mogul, which is in the engineering phase at Dorris Yachts in Bremen, Germany.
