Seaf is designed to make people on board perceive something more than just being free in the middle of the sea. The main objective is to make the guests feel constantly connected with the most peaceful form of nature. Seaf is an 80 metre long motorsailer, with an elegant and sporty line that integrates the best elements from a sailing yacht and a motor yacht. Seaf is powered by two Dynarig sails and an hybrid diesel-electric engine propulsion. Ecology is pivotale to this project. This sustainability concept is also visible from the outside of the yacht and this is achieved through elements taken from biomimetic architecture. Large windows enhance sun rays and open spaces, allowing the light to flow inside. Among the suggestive spaces on board, there is the beach area in the tender zone and the lounge bar, which connects the main saloon with the pool area. Here the guest feel close to nature and the elements, such as the waterfall that flows from the sun deck to the main deck, and the tree surrounding the mast that becomes a characterising feature of the yacht.
