wow that is corroded and would be a sloppy boat, the inserts for the beam ends are called I beams enable you to really tighten your beams without compressing the tube and are supplied by Brisbane Catamaran Centre. I'm assuming your welding a patch on those beams Lars or did you replace them? Definitely need the beam centre post. From what I hear the 18 square goes upwind brilliantly, outpointing most big cats but is slow off the wind, so I'm considering a spinnaker for mine but I do know they are a bit tender in the bows as far as pitchpoling so I'm reluctant to add the weight of a bowfoil up front.
