Bzzzztttt!! Actually it WAS originally called Duck Tape, as it was made from durable Duck Cloth. It was developed for the military in WWII to waterproof ammo boxes, repair boots, etc. HVAC applications came post-war.
You are right....75 years ago. Today "Duck" is the brand name of one of several duct tapes. It is not waterproof, of course, so wouldn't work to hold the ship together, and gaffer's tape would be worse.
