More S860 crossbeams: Centre bearing blocks

The Starwind 860 trimaran's crossbeams are joined on the boat's centreline by a massive hinge pin. This mechanism ensures that the two outriggers fold in sync. The peak load on the centre bearing could be up to 41 kN (about four tons) port-starboard or 11 kN up-down, and the structures around it need to reflect that.
