In my post Parametric Rolling of a Car Carrier in Head Sea. I wrote that hidden flaws, are more likely to be revealed in heavy weather. An example is the car ship Figaro - Inadvertent Release of CO 2 - in that case heavy weather was the trigger that casued the unintended release of CO2.
Another, less obvious example is the case of the Sailing vessel Satori which was the sailing vessel in both the book and movie The Perfect Storm.
The Satori is:
a short masted, heavy displacement rig. She weighs 11 tons and is designed for heavy seas. Eleven stays keep the forty foot mast secure. When the boat was built Ray requested heavy rigging to be certain that Satori could handle more severe storms.When the owner and captain of the Satori, Ray Leonard, hove to in 40 kt winds and 30 ft seas he felt confident that his vessel was well within its limits but was unexpectedly forced to abandon his vessel. Leonard's confidence in his vessel was not misplaced, the Satori was later recovered with little damage. The path of failure was not the vessel but the crew: From the story: He (the captain) was unable to convince the crew that this motion was uncomfortable but not dangerous.
This second knockdown put the crew into a heightened state of panic. They began to insist that they call the Coast Guard for a rescue. Karen believed that the boat was going to break up any minute. The captain explained that there was no need for a rescue and that Satori had been through this before and would ride out this storm. At this point, Susan and Karen were not listening and kept insisting that they wanted to call. Ray agreed to let them call,The Coast Guard required Capt Leonard to abandon his vessel and sent a HH-3F helicopter from Elizabeth City, N.C. Rescue swimmer Dave Moore went into the 30 ft seas and pulled the captain and two crew out of the water.
It is not only the vessel that encounters heavy weather, it is the vessel, crew and cargo. Operating vessels, and their crews, near limits increases risks and chances of failure, - but the path of failure may not be the one expected.
The son of Ray Leonard, posted a rebuttal to the book The Perfect Storm.
