How light is it possible to build a 20 feet platform that is tough enough to endure hard sailing and tough conditions(texel, worrel etc)? Some will say that the M20 at 120kgs is already pushing the limit, and might have pushed it too far as some M20s have proven to be a bit too fragile in rough conditions. Macca, who by the performance and sheer looks of his upgraded Taipan 5,7 obviously knows what he's doing, recently mentioned in the Super Taipan thread that he thought it was possible to push the weight of a 20 feet long,10 feet beam cat down to 105kgs. I know Wouter disagrees, but what about the rest of you?
