The 24m yacht Zattera is currently under construction at Castagnola Yacht in Lavagna, Italy. The idea behind Zattera is following the sound of the sea, sailing slowly: the dimension of serenity and peace at sea. It originally came from Renzo Piano and Olav Selvaag, Nauta Design and Francesco Rogantin gave shape to that idea and Siemens Energy created its propulsion system. Fundamental aspects of the project were increasing serenity to the maximum and reducing noise pollution to a minimum. 



Inspired by the dream of being able to live life at sea in spiritual silence and in harmony with the natural environment, Zattera, which in Italian means raft, is more a means for enjoying life at sea than a proper yacht. Built in sustainable yet durable wood, its design is pared down and modern with clean and simple hull lines.

Zattera’s hull has clean lines, which give extra emphasis by a light and transparent glass superstructure that almost seems to float and that allows for direct, unhindered visual contact between man and nature. 



She can navigate at up to 12 knots with a 10,5 knot cruising speed. Siemens Energy’s hybrid propulsion system was fundamental in reducing emissions and careful attention was dedicated to eliminating vibration and sound pollution in the surrounding environment. Zattera has lithium-ion batteries and can navigate in silent mode under electric power only. The diesel generators were purpose-developed by Mase Generators for Siemens Energy with Volvo Penta D4-300 motors using variable speed technology with permanent magnet alternators in order to minimize consumption and emissions.



Solar panels will also be mounted on Zattera to create a zero impact and no cost renewable energy source. All of these systems were purposely created to allow Zattera significant autonomy both while navigating and during use in hotel mode.  

The interior layout can accommodate two owners and their four guests across six cabins. The styling is understated, clean and simple while ceiling heights are generous throughout. The saloon in the lower deck is directly connected to the coachroof via symmetrical stairs. Natural light floods in from a large skylight placed at the centre of the saloon. The floor is at the same height as the waterline so you feel as if you’re walking on water while inside the boat.
