At the risk of appearing curmudgeonly (not for the first time), I agree with Dan Cooper. The public, spurred on by novelists and Hollywood, seems to suffer from a highly romanticized conception of piracy that's taken leave of reality. Historically, people referred to as "pirates" were a collection of unsavory criminals who shared one major thing in common: a desire for an easy way to make money. Piracy, like most forms of criminal activity over the centuries, had (and continues to have) money at its root.
I'm aware of one vessel that actually may have been built as what could be called a "pirate ship." In 1717 a wealthy businessman named Stede Bonnet decided, for reasons now unclear, to take up piracy. He apparently had a two-masted sloop, which he called the Revenge, built for the purpose. Here's a version of the story: http://www.thewayofthepirates.com/famous-pirates/stede-bonnet.php
But the vast majority of people who resorted to piracy did so with ships they took from the legitimate owners. The ideal pirate vessel, so far as most practitioners were concerned, was small, fast, and maneuverable, and carried a few guns so as to overpower unarmed or lightly armed merchantmen. The pirate ship had to be small, because (among other considerations) the people who operated it got paid out of the proceeds of their criminal activity. "Blackbeard's" Queen Anne's Revenge, the remains of which may (or may not) have been found recently near Beaufort, NC, appears to have been one of the largest vesels used for the purpose. The notion of a huge, clumsy, expensive warship like the Wappen von Hamburg, the Sovereign of the Seas, the St. Louis, or even La Flore serving as a pirate vessel is utterly absurd; it makes about as much sense as a group of modern pirates (they're out there, all right - in considerable numbers) operating the U.S.S. Nimitz or the QE2. Those Lindberg kits are, in terms of historical reality, sheer nonsense - a marketing ploy (or, perhaps we could say, modern corporate piracy) with a gullible public as its target.
Professional maritime historians and museum curators tend to roll their eyes or grimace when the subject of piracy comes up. I don't exactly blame them. I can remember, during my brief museum career, getting mighty tired of visitors who walked right by some of the most interesting and important maritime artifacts in the world, saying "ok, but where are the pirate cutlasses?"
People who are serious about maritime and naval history tend to blame the current "piracy" fad on Disney. Actually those people are, in many ways, wrong. One of my favorite books on the history of piracy (I don't have many; it's not a subject in which I've ever been particularly interested) is David Cordingly's Under the Black Flag. Mr. Cordingly was the curator at the National Maritime Museum in Greenwich who organized a blockbuster exhibition about the history of piracy there in the early1990s. Visitors flocked to see such things as the coat Dustin Hoffman wore in the movie "Hook." Few of them noticed that the exhibition contained scarcely any genuine historical artifacts connected with piracy - for the simple reason that such artifacts don't exist. But it was a terrific show. I walked out of the gift shop with an inflatable plastic parrot on my shoulder. (I still don't know which of my kids, or their friends, eventually absconded with that parrot.) Mr. Cordingly's book not only reviews the actual history of piracy but considers in some detail the public's fascination with it down the centuries. The Disney people are, in a real sense, just carrying on a tradition that goes back to Daniel Defoe, James Barrie, and Robert Louis Stephenson - among others.
The word "pirate" seems to have a near-magnetic force as far as the public is concerned - and there's no point in trying to resist it. I do hope at least some of the people who go to those movies will be inspired to pick up a genuine maritime history book. Or at least dig into the fictional literature about the subject. It's as enticing as it ever was. A few months ago I spent some hours at my workbench with an unabridged audiobook version of Treasure Island. My wife has a slight crush on Johnny Depp; I think he's an interesting and extremely talented actor. And Captain Jack Sparrow certainly is an interesting creation. But as far as pirates go, there's just no way he can play in the same league as Long John Silver.
