As my contribution to HP ideas that will never actually see the light of day, I propose articulating LW hulls. The idea is to attach the spar to the beams rather than to the hull. The rudders are already on the beams, so the LW hull is just wave piercing and floating, potentially. The idea would be to bury the spar into the hull but actually it is mounted in a pocket in the beams that is socketed in the hull. Imagine a wheel like container (at least below the level of the LW hull, that is relatively rigid laterally, but free to move around an axial point located pretty much where the mast comes out of the beam. I was fancifully thinking of golf balls as the source of bearings between the hull and the mast pod. This would allow the two hulls to respond free of one another, and potentially react separately to the wave train.
I have been an admirer of the articulated tris the gougeons have worked on over the years. Adrenaline is now sailing:

Of course this could be a really bad idea. While it would reduce the racking in the beams, it would also eliminate any stabilizing effect the LW hull's long footprint has on the WW hull's shorter footprint, while the latter could be swinging the spar forward and aft. In Adrenaline's case the main hull and rig are the long hull, and the amas are articulating. If it worked it could be that the disconnected LW hull wouldn't need to be super long any more because it isn't stabilizing the action of the WW hull. Taken even further both hulls could be long, or the WW hull long and the LW hull not so long since in this version it is no longer functioning as the leveling hull. Lots of stupid stuff to think about.
