The exterior design of the yacht was developed by Zuccon International Project. The main difference between the yacht and the previous models of the SX range concerns the stern: the SX100 centralizes and expands the spaces, connecting the interior with the exterior. The large living area, consisting of a covered saloon with large windows and mirrors that reflect light, enhancing the light tones of the natural materials used in the project, merges with a spacious beach area and two side terraces. The beach club can be used as an area for sunbathing by the water or for storing various water toys and a large tender up to 5.65 meters long. In terms of performance, the SX100 is powered by four Volvo Penta engines, giving her a top speed of up to 23 knots and a cruising speed of 20 knots.
The interior of the Sanlorenzo SX100 flybridge motor yacht can accommodate up to 8 guests in 4 cabins. The owner's cabin is located forward on the main deck, while three guest cabins are located on the lower deck directly connected to the lounge area. Up to 5 crew members can also be accommodated on board.
