Around September last year Derecktor issued this press on the progress of "Cakewalk". It gives an idea as to the various conceptions of the yacht, a fairly detailed look at the "BOATHOUSE"/tender bay region for the 3 custom large tenders and other toys, the main tenders are as follows, a RIVA, an INTREPID and a VIKAL LIMO. They are all over 30-feet long. The PDF also deals with most of the other aspects to the yacht. It makes very interesting reading if you haven't done so already.
