(Absolutely, positivily nothing to do with (water-borne) ships - or books for that matter - but what the heck. ^_^ )
Webcomics I Reccomend
Note that all three of these are serials, so you'll want to read through the archives to figure out all that is going on.
Schlock Mercenary
"Roast carnage, coming right up" - Sgt. Schlock
The eponymous BLAM-loving blob and his fellow 31st century space mercenaries fight governmental corruption, renegade AIs, warmongering koalaoids...and the lawyers of the Partnership Collective!
(A+, Two Thumbs Up, a Must Read, etc., etc., etc...)
Zortic
'Not your average "little green man in a flying saucer".'
Follow the (mis)adventures of two young, Earth-pop-culture-loving aliens as they roam known space with their game-show-prize ship and its mechanic/mystic/generally weird guy...
(Featuring hilarious spoofs of
Lord of the Rings,
2001,
Star Trek VI,
Space: 1999, and just about anything else you can think of!)
Arthur, King of Time and Space
Arthur Pendragon, King of Britain; Arthur Pendragon, High King of all British Space; Arthur Pendragon...high schooler?
It seems the sword in the stone was more powerful than even Merlin had thought!
(Can be read without resource to the archive, in a pinch)
