The yacht's layout features three distinct zones, starting with the stern beach club at sea level. This area includes a multifunctional transformer that serves as a bathing step ladder and gangway. Ascending two side steps lead to a large sun pad facing aft and a lounge area furnished with sofas and a coffee table. Opening side balconies enhance the livability of this space.

The third zone features an outdoor table that seats up to eight people. The aft galley and bar, with an up/down tinted glass partition, offers flexibility for both formal and informal occasions such as show cooking and cocktail parties. To the left of the bar, a staircase leads to the sun deck.

The sun deck, equipped with a carbon hard top, includes the second helm station and offers a private, versatile space for guests. It features two large sun pads at the stern, a lounge area with sofas, an L-shaped bar, and a 12-seater table.

Maximizing interior space, the design includes a port-side walkway to the bow and an opening balcony amidships near the lounge, allowing guests to enjoy the view from indoor sofas. The bow features a circular swimming pool with sun loungers and sofas.

Inside, a second combined galley and bar leads to a bright lounge with floor-to-ceiling windows, furnished with semi-circular sofas and armchairs. A circular table that seats ten completes the setup. The command bridge is located on the main deck forward, adjacent to a staircase leading to the lower deck. The lower deck houses four double cabins with private bathrooms and the owner's cabin with a double bathroom.

This displacement yacht has three MAN engines, each delivering up to 2,200hp. The Viper 120 can achieve a top speed of 33 knots and a cruising speed of 26 knots.
