Millennium Falcon is easily my number one favorite, but the thing that has always bugged me about it is that for a cargo ship, it didn't seem to have much of anything in the way of cargo space or crew amenities, or any practical way to load it.
The creators of
Firefly
got Serenity right because they actually accounted for all the space and how the ship was laid out, including a spacious cargo hold with a large, rear door.

The Raza!

You'd have to define "favorite." If you mean the space ship I'd most like to be on..No. Absolutely not.
No way in hell
. Can't even take a shower. And the galley..nope.
I'd want something with a lot more amenities. Like a cruise ship version of the Enterprise D.
Though Lazarus Long's ship Dora from "To Sail Beyond the Sunset" would be nice, but no mention of holodecks.

1. Galaxy and Intrepid class starships - Star Trek
2. TARDIS - Doctor Who
3. Deep Space 9 - Star Trek: Deep Space Nine
4. Ancient City-ships - Stargate: Atlantis
5. Space Colonies - Gundam
6. Space Stations - Babylon 5
7. Leviathans - Farscape

Something about Theron's quarters in Prometheus really worked for me. But that wasn't a separable mini ship "Captain's Yacht" like Picard's, right?

Right after Sulaco and Event Horizon.

Serenity or Moya from 'Farscape.'
Wasn't me

The Whitestar-class of ships on Babylon 5 are my favorite fictional space ship.

She's a butt ugly old klunker and I love her with a passion.
Millennium Falcon's another favorite of mine. Not sure which of those two boats I like better, but Serenity's definitely at least tied for first place.

I'd've gotten away with it, too, if it weren't for you meddling kids.

I would actually watch a movie or skit called "Space Boat". Something kinda facilities about it, i think.

The serenity is one of my faves. The m.falcon, b-wing fighter, and the LEXX are my top choices.

Serenity is a gorgeous ship, no doubt.
But my heart will always belong to the Enterprise from TOS, hell even the refit version was still gorgeous.
I always thought the Andromeda was an underrated design.

My mistake, sorry.
Gotta go. Kisses.
They're back!

I was speaking of Doctor Who.
Read it again, the context changes.

The crew doesn't. They all just say Serenity.

I suppose currently my favorite would have to be Serenity.
Probably because it feels like a home with the decorations Kaylee adds to her cabin and the dinner table where the crew takes their meals. It seems to have a soul provided by the crew through their comments through out the series.
Millennium Falcon was my favorite for years before Serenity, but we only see bunk space once and they never ate aboard her once making the ship loved and appreciated but still just an appliance.
The Raza from "Dark Star" has attempted to bridge that gap but is way off, too dark and doesn't seem to come close.
My all time favorite space boat? "The Tardis" from Doctor Who but only just a hair above Serenity only because it can travel in more than 4 dimensions. Tho, I would rather ship out on Serenity since there are no aliens and less danger.
(P.S. "The" is correct use of the name since all through the series they refer to it as such.)

It's right up there with the Millennium Falcon. I think what makes Serenity and MF believable is that they are not gleaming super-tech ships, like most of the Star Trek ships were. They are beaten and battered and show signs of wear and tear - they have character.
The DVD extra about the ship as a character is interesting.

Exactly this

I love Serenity. More than just about any other space ship, Serenity feels like a home.
Let's be bad guys.

It's a nice ship and I wish someone would make a mod of it in a space game.

Yes, very often said incorrectly.
Even those in the Navy often add 'the" before a name.
it is the same method by which old wives tales and urban myth/legends are born.
A mistruth repeated often enough gains the weight of truth.
Another one heard commonly enough is the term "Aegis Class Cruiser" or "Aegis Class Destroyer"
Aegis is not a class of ship. It is a Combat Sensor/Weapons Integration System. It is installed aboard Ticonderoga Class Cruisers and Arleigh Burke Class destroyers. (as well as a few select foreign warship classes like the Japanese Kongo Class).
I joined the Navy to see the world, only to discover the world is 2/3 water!

Ah, thanks! Very often said incorrectly, then.
Gotta go. Kisses.
They're back!

That's a holdover from real life.
In real life, a Ship's name is it's formal name, not a title.
"I served aboard USS Halsey"
is correct.
"I served aboard the USS Halsey".
is not correct.

Yes, but it's just Serenity, not "the" Serenity. I forget which ep it is, but Inara corrects someone about that. Possibly Bushwhacked?
Gotta go. Kisses.
