Literary Critique of Superhuman Swimming
Aquaman (DC) has this power as do all members of his mother’s race Atlanteans. According to the Who’s Who in the DC Universe, V1 #1, Aquaman is said to be able to swim 100 miles per hour.
Marrina (Marvel) can swim 48 miles per hour and even faster if she sheds her skin and uses a frictionless skin underneath (Official Handbook of the Marvel Universe V1 #7).
Namor (Marvel) has this power as do all members of his mother’s race Homo mermanus. According to the Official Handbook of the Marvel Universe V1 #10, Namor can swim 60 miles per hour. This means that according to canon sources, Aquaman can swim faster than Namor.
Olympic level humans can swim at 1.64 meters per second, or approximately 3.7 mph (Toussaint, HM & Truijens, M 2005, ‘Biomechanical aspects of peak performance in human swimming’, Animal Biology, vol. 55, no. 1, pp. 17-40.). An imaginary swimming race between all Olympic swimmers.
The fastest fish in the world is the sailfish which can travel 68 miles per hour. The means Aquaman is can swim faster than the fastest fish in the world. Namor swims more or less at the same speed as a sailfish (60 mph vs 68 mph).
Namor uses his superhuman swimming ability offensively in the Incredible Hulk V1 #118 in order to create a whirlpool. The Hulk has been given a tablet that lets him breath underwater in order to make this underwater fight possible.
Namor is basically employing a speedster trick underwater. Quicksilver uses his super speed to do the land version of the whirlpool trick in Amazing Spider-Man V1 #71.
Aquarus (Image) can swim about as fast as Namor using conventional means but uses something called supercavitation to swim 500 miles per hour (Official Handbook of the Invincible Universe #1).
However, super cavitation is not swimming in any normal sense of the word but would be yet another superpower and there is research to apply this phenomena in real life!
