Why does Ishmael choose Pequod but not another ship?

Queequeg had been diligently consulting Yojo, the name of his black little god, in preparation for selecting their craft. There are three ships up for three-year voyages: the Devil-Dam, the Tit-bit, and the Pequod. The Pequod is named after a celebrated tribe of Massachusetts Indians. The Pequod is a ship of the old school, rather small and with an old fashioned claw-footed look. The Captain was once Peleg, now retired after many years. Ishmael introduces himself to Peleg, who is suspicious because Ishmael has no whaling experience. Peleg tells Ishmael that Ahab is now captain of the ship, and he has only one leg, for the other was lost by a whale. Peleg and Bildad, both Quakers, are owners of the boat, and are "fighting Quakers." Bildad and Peleg look over Ishmael. Bildad is the "queerest old Quaker" he ever saw. Peleg and Bildad negotiate the lay (share of the profits) for the voyage, and Ishmael demands the three-hundredth lay. Peleg and Bildad argue with one another about how much of the lay they should offer, and their argument nearly leads to violence between the two. After Bildad leaves, Ishmael signs the paper and asks to see Captain Ahab. Peleg describes him as a queer man, but a good one, "grand, ungodly, god-like." Peleg compares him to the Ahab of old, who was crowned king, but a vile one. Before even meeting Ahab, Ishmael feels a sympathy and a sorrow for him.
