Episode 199: Deadliest Catch Crabtastic Special


A fisherman will be pulled to the bottom of the ocean if he is caught in the coiled rope when a crab pot is deployed.

plausible
With the help of Deadliest Catch captains Johnathan Hillstrand and Scott “Junior” Campbell, Jamie and Adam set out to test this myth. A scale model experiment showed that normal (spring) coiling did not consistently pull someone off the boat, but over-under coiling did. However, for the full-scale test, a regular coil was used because it is more frequently used in real life. In the first series of tests, with Buster standing away from the boat’s railing or leaning on the railing, the rope consistently caught his leg but did not pull him over. In a final test, with Buster looking over the railing, he went overboard and was dragged along with the pot to the bottom of the bay. This myth was deemed plausible because the rope would consistently grab the fisherman’s leg but it would not consistently pull him overboard.

Working a 30-hour shift with 20-minute naps every six hours results in double the performance of not getting any sleep.

confirmed
On an anchored ship, the Build Team set up a crab-fishing themed obstacle course to test their mental and physical abilities. Kari and Tory both completed the course with perfect scores when well-rested. Attempting the course after being awake 30 straight hours resulted in dramatically low scores. When they added the brief naps to their 30 hours of wakefulness, they both achieved more than double their previous scores.

The 800 lbs (360 kg) crab pots used on Deadliest Catch are indestructible.

busted
The fishermen claimed that one of their pots would survive a 3 lbs (1.4 kg) C-4 blast without any damage to its steel structure. After a test with the C-4 in the middle of the pot, only the webbing was damaged so they appeared to be correct. However, after the Build Team strategically placed the explosives below the steel struts, the pot was heavily damaged.

Myth Status Notes
A car with a JATO rocket attached can speed up to 300 miles per hour (480 km/h), become airborne, and impact with the side of a cliff. A revisit of the "Jet Assisted Chevy" myth from the first pilot episode. Re-Busted For this experiment, Adam and Jamie planned the particulars for two launches, while the Build Team modified a large dump truck with a protective metal cage around the exterior of the cab for use as a mobile command bunker (later dubbed "the Beast"). The first test involved a Chevrolet Impala with five rockets attached, fired as it approached a line of 50-pound (23 kg) sandbags. The car crossed the berm at over 200 miles per hour (320 km/h), but only managed to get airborne by flipping and tumbling several feet beyond the sandbags, when Adam lost control of the car; there was no indication that the car lifted off at all going over the sandbag berm. The second test involved a second Impala with six rockets attached, launched off a giant ramp as in the Supersized Myths special. This time, the car hit the ramp perfectly straight, but immediately after leaving the ramp, it nose-dived, flipped end-over-end, and landed about 600 feet (180 m) away. The MythBusters came to the conclusion that the myth scenario is impossible simply because cars are not shaped like rockets and are therefore not aerodynamic in a way that supports flight.
