Like for Only Lu, the first of the series, the construction accomplished under the sign of lightness, thanks to the use of state-of-the-art composite materials, the Sprint technology and the male mould allowed to keep the displacement of this 20-meter sailing yacht under 18 tons. The layout of the interiors of the Mariposa features, starting from the prow, the boat owner cabin with two low beds on the sides, the open space living room with dining and lounge area, kitchen and chart table in the middle and, at stern, two cabins with twin beds also with private bathroom as the boat owner cabin. The twin-bed crew cabin is located at the extreme prow. Under the large space at stern of the two posts of the steersman, there is a large garage which can host a 3.80 meter custom tender. The garage is entered by lifting the stern transom.
