How USS Narwhal Rode Out Hugo
With word that two Pascagoula-based frigates sortied in the face of Hurricane Katrina, I'm reminded of the story they told around Charleston about how the boats there survived Hurricane Hugo, especially USS Narwhal (SSN-671). What I heard kind of matches what I found here:
Narwhal sustained minor damage on 22 September 1989 when Hurricane Hugo hit Charleston, South Carolina. The boat was moored with nine double wires and two three-inch ship's lines in preparation for the storm. All but one of the lines parted during the first half of the storm, and the boat drifted into the Cooper River. Tugboats and Narwhal's crew tried unsuccessfully to move the submarine back to the pier before the second half of the storm. As the storm resumed, Narwhal submerged in the river and rode out the remainder of the hurricane with only part of her sail exposed.
From what I understood, all the subs that could got underway, but Narwhal was in the middle of an upkeep and they couldn't get her back together in time. So, when they figured out that the storm was doing so much damage, they basically submerged at the pier and snorkled. If anyone else knows if this is what really happened, please let me know.
