What are some similarities and differences between Hawthorne's "Young Goodman Brown" and the opening chapter of Melville's Moby-Dick?

Various similarities and differences (but mostly differences)
exist between Nathaniel Hawthorne’s short story “Young Goodman Brown” and Herman Melville’s novel
Moby-Dick. Here are a few of the
similarities:

• Both works are set, at least initially, in
  New England.


• Both works focus on journeys made by young
  men.


• Both young men have names that prove to be symbolic.
  

Here, however, are a number of significant
differences:

• Melville’s Ishmael narrates his own journey;
  Brown’s journey is reported by a narrator.


• Ishmael, at the time of
  his journey, is apparently unmarried; this is not true of
  Brown.


• Ishmael, in the very first paragraph of the novel, displays
  an attractive sense of humor; Brown is rather humorless throughout his tale. Ishmael is the more
  complex of the two characters.


• Ishmael, at first, is much more
  isolated than Brown. Brown meets a companion in the forest and meets other acquaintances along
  the way, while Ishmael is initially much more of a loner.


• Ishmael
  will be journeying out onto the sea, while Brown will be journeying into the
  forest.


• Brown never seems to have journeyed much beyond his small
  town before, whereas Ishmael is familiar with the large city of New
  York.


• We are offered very little insight, at first, into what
  Brown may be thinking; Ishmael, in contrast, is speculative and openly reflective right from the
  start.


• Because Brown does not narrate his own story, he has no
  opportunity to address the reader, whereas Ishmael addresses his readers in the very first
  sentences of the story, as if beginning an extended exchange with
  them:

Call
me Ishmael. Some years ago - never mind how long precisely - having little or no money in my
purse, and nothing particular to interest me on shore, I thought I would sail about a little and
see the watery part of the
world.

• Brown’s story deals
  quite explicitly with matters of good and evil, whereas the focus on good and evil in Melville’s
  novel is not especially stressed in the very first chapter.


• The
  style of Hawthorne’s story is fairly obviously symbolic and allegorical right from the start; the
  first chapter of Moby-Dick, however is more convincingly and deliberately
  realistic.

Other contrasts might easily be listed, but
these are enough to indicate some of the significant differences between the two
works.
