Wally has signed a business partnership with brokerage houses YCO and Yachting Partners International (YPI Group) to develop and organise the customer plan of the WHY concept.

Several design changes have been made since the full-scale mock-up was built in Ancona in September 2009, as part of the R&D programme. These changes include a re-design of the sliding roof to improve the efficiency of its photovoltaic panels and fully exploit the interior living space. A re-arragement of the interior aft of the wheelhouse and a revision of the internal and external volumes of the upper and owner decks to increase the accommodation space. Finally, the walk-around deck now has a maximum gradient of eight degrees and the forward swimming pool has been made larger.
