 Amazed at this discovery, Chatterton and his fellow divers make a pact to keep the U-Boat a secret until they can discover its identity and claim credit for its discovery.This is to prevent "wreck-jumping" (wherein another person claims credit and/or removes objects from the wreck).Unfortunately, this pact is broken almost immediately by a couple of members of the team who decide to tell close friends, and the secret is let out.
