What are the nine gams on the other whaling ship?

In the context of Herman Melville's "Moby-Dick," the nine gams refer to the encounters between whaling ships at sea, where they exchange news, stories, and information about whale sightings. Each gam is an important social interaction that highlights the camaraderie and competition among whalers. These encounters can lead to shared intelligence about whale locations and hunting strategies, enhancing the overall whaling experience. The gams illustrate the interconnectedness of the whaling industry during that era.
