Before the invention of steam and diesel engines, transoceanic commerce was conveyed in huge sailing ships. The sails were large, with hundreds of yards of ribbing securing them to the tall masts. The most dangerous job on board was that of climbing the rigging to adjust or repair the sails. The mortality rate amongst these sailors was high, especially when there was rough sea or high wind. Survival depended on maintaining a constant grasp of the ropes while climbing or working. It was common that these sailors tattooed these letters across their knuckles: H-O-L-D F-A-S-T. -- Kelly
