In looking at images and drawings of Terrestrial pre-modern ships
called 'galleons', I note that while the designs are quite varied,
there are a few common charateristics:

If you assume that the height amidships is the 'deck line', then there
is a section forward that is perhaps one deck above the deck line, and
a higher raised section, perhaps three decks above the deck line, aft.
Also, like all seagoing ships, they are narrow forward, widest
amidships, and somewhat narrower - but not drastically so - aft. The
main body of the ship is two, perhaps three, decks from deckline to
just above the bilge.

I am ignoring the question of size and/or displacement. The rigging is
more or less similar across all such ships, but this is not relevant
to my thinking at the present time.

I don't insist on the deck counts given; that's just for visualization
purposes.

What I'd like: A design for a "Star Galleon".

* It may be a pure cargo ship, a pure passenger ship, or mixed use;
  you, the designer, decide.

* It may be a workhorse of a hauler/liner or a noble's plaything.
  Or anything in-between.

What you should include:

* The stats. Obviously. Any of the standard formats will do.

* A Worksheet. Again, any of the standard formats will do.

* Descriptive matter. This should discuss the ship's role, why it was
  designed as it was, in-universe advantages and disadvantages of the
  design, perhaps a spotlight on one or two notable members of the
  class, and so on.

* Any other commentary or information you feel would make the ship
  more interesting.

* Highly desirable, but not mandatory, would be deck plans.

Generally speaking, Timothy Collinson's Naklaad can stand as a good
exemplar of a design submission - save that whilst Mr Collinson went
"all in" and provided stats for pretty much every Classic-compatible
system out there, you don't have to - one is fine (but if you do want
to do it for more than one, I certainly won't object!).

As an adjunct to a Classic-compatible design, a reworking using TNE,
T20, or GURPS Traveller (3e or 4e) would be well-received - but not,
by any means, mandatory.
