      No I hadn't, thanks. Interesting .....

      He's right that traditional ships did not have ballast. From what I understand, the old lumber schooners sailed both unballasted and without cargo when sailing up to get a load of lumber. Many other ships took a load of rocks when sailing empty to bring them down to their lines.

      Tea, being such a light cargo, could not bring a tea clipper down to its lines without added ballast, at least that's how I understand his comment.

      Please verify for me one question: I understand that while these ULDBs are great for down wind sailing, they are unable to sail close hauled in waves, which is why they have motors. My understanding is that waves that a heavy displacement boat can punch through will stop a ULDB. Is that true?
