This argument is often parroted, but is just as bogus as the others. The Ark was built for stability, not movement. A flat-bottomed barge like the Ark wouldn’t have problems with sag. If the lower deck were made of logs, four layers deep, it would have been very sturdy. If they were teak logs, especially specially treated by being buried for a while, the ark would have been especially seaworthy. Woodmorappe points this out too, and much more, so Isaak is dishonest to ignore that. Korean naval architects have confirmed that a barge with the Ark’s dimensions would have optimal stability.
