What gloomy assosiation does ishmael make when he comes across the spoutter inn ?

I see this in chapter 3. The Spouter Inn reminds Ishmael of the bulwarks of some condemned old craft. There is a long, limber portentous, black mass of something hovering in the center of a picture of a painting there; it bears a faint resemblance to a gigantic fish, but in fact represents a Cape-Horner in a great hurricane. On the opposite wall is an array of monstrous clubs and spears. The innkeeper tells Ishmael that he must sleep two in a bed, which he dislikes and will do so only if the innkeeper has no other place for him. The innkeeper tells Ishmael about the ship harpooner, a "dark-complexioned" man with whom Ishmael will share a bed. Ishmael suggests that he will sleep on a bench instead, but it is too uncomfortable and he must sleep in a bed. Ishmael goes into the harpooner's room, where there are fishhooks and harpoons. The harpooner, who is from New Zealand, appears dangerous. The harpooner, Queequeg, undresses to show his tattooed chest and arms, and has a tomahawk with him. Ishmael gets in bed with him only after the landlord makes him stash his tomahawk away. Ishmael never slept better in his life.
