Interestingly, British civil and mechanical engineer Isambard Kingdom Brunel built a steamship (the Great Britain) in 1843 that had almost the same proportions as the Ark, although it was smaller. This was regarded as a remarkable feat of Victorian and maritime engineering. The Great Britain was the first large vessel to be propelled by a screw propeller.
Making it seems like this was an similar to the wooden ark. However the Great Britain was an
iron ship.

The ss Great Britain was the world's first wrought iron hulled, screw propellor-driven, steam-powered, ocean-going, passenger liner. At the time of her launch in 1843 she was also the world's largest ship, with twice the tonnage and 100ft longer than any previous vessels.
Don't you think that was just a bit deceptive? In any case it has no bearing on the seaworthyness of the wooden ark. It would have hogged and leaked like a sieve pitch or no pitch.
