I see that Palmer Johnson has a new trimaran mega-yacht. It is 48 meters long. The 1% must be doing very well; it’s all carbon fiber. The design looks very post modern multihull: like Mike Schacht work, to the third power. The amas are just vestiges though; they could not support anything. However, as the guys from NAVSEA once reminded me, those amas could diffuse the thermal signature, protecting it from heat seeking missiles. It really is just a typical portly mega-yacht, albeit in carbon, with amas pasted on.
