SanLorenzo Launches Second 460EXP, "X" The second unit in the SanLorenzo 42-meter 460EXP line has been launched and is called "X". Just to clarify, 460EXP does not suggest the yacht is 46-meters long, it is actually 42.2-meters in her overall length. It is the same scenario for her debut hull sister called "Moka". The line is actually around 460 GT which is where the 460EXP term is derived. Although X is similar in design she is painted differently making it fairly easy to recognize her should they both turn up at the same marina. Her steel hull features a grey colour, white superstructure and black accent on the mast and domes.
