Yes, I bet you are curious :-) but its easy, its also the biggest multihull racer, Spindrift 2, the boat that with another name (Banque Populaire) holds the absolute record of the fastest circumnavigation. The BP skippered by Loick Peyron and a full crew took 45 days, 13 hours, and 43 minutes to do it. The boat also holds the Atlantic crossing record with Pascal Bidégorry (and crew) in 3 days, 15 hours, 25 minutes and 48 seconds at an incredible average speed of 33K.
Of course the question is not if this would be the fastest solo sailingboat but if this monster can be sailed solo on a Transat.
On the last Route du Rhum Franck Cammas sailed solo the Trimaran Groupama, the previous holder of the two mentioned records, to the victory (solo). Many did not thought it was possible but Groupama even if big is not the size of this one. Would Yann Guichard be able to do it winning in November the next Route du Rhum? The boat has been adapted in what regards rigging, the mast is smaller and he is training for it and the images are beautiful and spectacular:
