"OMG I am teh OFFENDED!!!"

An occasional syndrome has come up in which someone seeks to play a historical or contemporary war scenario: WWII, Vietnam, Iraq, Somalia, what have you.  Then, all of a sudden, Social Justice Warriors popsup screeching -- it's insensitive, you see, and "trivializes" the true nature of human suffering that goes on in such conflicts.  How dare people turn jihad and genocide into a game?

I note their opinion (barely) and move on.

If it sounds like I treat the notion cavalierly, yes, you'd be right; I do. There are many aspects of roleplaying that many people find distasteful for whatever reason ... heck, I've seen more than one player leave the hobby because they couldn't hack the casual and pervasive violence inherent in it.

And beyond that?  A very great deal of our popular entertainment, from books to movies to music to television, is disrespectful of societal norms of decency and fair dealing. But however much "geto rap" which glorify murdering police or beating women disgusts me, I'm not going to barge in on rap discussion boards moralizing at unsuspecting people minding their own business.

We "owe" it to the victims of the Holocaust no more to not play RPGs set in WWII than we owe it to them not to play Axis & Allies, War in the Pacific or any other wargame that purportedly "trivializes" their suffering. What indeed trivializes them is the notion that a handful of people sitting around a table with dice could somehow detract from what happened to them.

In one such debate, a poster flung at me the hypothetical of a campaign with SS Totenkampf PCs.   Would I support that?  Huh?  Huh?

Surprise, said I. If someone did want to play in an SS game, I was neither prepared to commit mayhem to stop them or to screech at their inhumanity.  There is an entire GAME system out there, one of the most popular there has ever been, in which PCs as a condition of survival feed on human beings. Gamers have been portraying torturers, cannibals, babykillers, rapists, death cultists, assassins, and monsters of every hue and description for the entirety of the history of RPGs. Somehow the world continues to turn, and I don't know of any gamers who march to protest Vampire games.  (Hell, show of hands: how many of you reading this could even count within a hundred how many sentient NPCs your PCs have killed in the course of your gaming career?  Your average long-term gamer's whacked out more people than Genghis Khan ever did.)

And, indeed, how many would pull this for other historical milieus? If someone was starting up a Scarlet Pimpernel game, would anyone imply they were monsters for trivializing the real human suffering and wanton butchery of an era that bequeathed the word "terrorist" to our language? Probably not ... but then again, that was ever so much longer ago, and the inhumanity to man has passed its sell-by date.

Anyway, a lot of gamers claim to feel such issues, deeply. This is another part of this syndrome that really bugs me ... that based on glancing at a headline or two or seeing a 15 second clip on the news -- and let's not pretend; that's about as much as 90% of gamers ever see -- people can claim to have some manner of "emotional connection" to a matter that "touches their lives."

Nonsense. That's on a par with claiming that having seen Bambi as a child gives one a deep understanding of hunting for game and all of its attendant issues.

Now, yes,: someone seeing a 15 second film clip of horror and war does have an emotional reaction. But it's shallow. The requisite "Oh, how awful!" and "Oh, someone should do something!" comes out, then the TV shifts to a commercial, followed by the weather and a clip on the giant pumpkin a local farmer grew, and man's inhumanity to man gets lost in the shuffle of ordering a pizza and settling down to watch the Bruins-Senators game. If that person gives Somalia another thought before the next news clip or headline, I would be very surprised indeed.

That, to me, is the really disrespectful bit, when the agony and violence of a region that's been suffering for decades is turned into a soundbite.

Scenarios They HATED

Every now and then it suits to put your PCs, if it can be managed, into a visceral hissing rage.

By way of example:

Champions campaign. The good guys are confronting the Big Bad in a hostage situation. Megaton is a known psycho and serial killer, and his particular power is an enormous point blank eruption of energy; Human Bomb-like, if you will. He has this sweet little blonde seven year old girl securely under his hand.

Anyway, the PCs negotiate to save the girl and the other hostages, and Megaton lets them go, finally starting to shove the little girl at them, saying "And here, you can have her too ..."

*** BOOM ***

... and Megaton vaporizes the tyke's head, the gushing torso stump flailing towards the party, splattering their costumes with gore. He's smiling like a Cheshire Cat as he finishes his sentence "... what's left of her. I recommend cutting her up for bouillon." * POOF * Big Bad teleports out.

The press and police are freaking out, the other kids are screaming, the girl's mother is howling ... and the players are all hissing, out loud, their faces contorted with fury.

The old ultraviolence, if used rarely and judiciously, sure packs a wallop.

===============  

Next General Player Hissing moment.

Here I had, for lack of a better term, an all-evil group; not just an edgy one, plain old full of predators. An old player was free on the all-evil night and wanted to come back to the campaign ... playing her old goody-two-shoes elven minstrel. So I thought about it some, and here's what I came up with: the elf's sister is a wild psi talent, was kidnapped, and ranged Laurelin from about a thousand miles away with a psychic "Helphelphelp!" Laurelin hires the blackguards to help.

Anyway, they follow the trail to a small time slaver in a port town, a genial old duffer who admits to buying Lindel from a kidnap ring, then reselling her to a caravan trader headed into the barbarian outback. Only then with a few mugs in him he cheerfully said how he'd never had himself an elf virgin before, recounted in obscene detail about the many times he and his men had raped her before selling her off, and finished up with ruminating about how she was probably the sex toy for the entire barbarian tribe by now. Hey, didja hear dat them Wolf Tribe warriors are hung as long as me forearm? 'Tis true, mates, I seen 'em meself!

Now having issues about rape in RPGs, I had never in any of the players' memories (nor, indeed, in the dozen years I'd GMed up to that point) thrown it in as an explicit element. Well, they were doing the hissing thing, and Laura herself was a fine shade of purple. They kidnapped the slaver later on that night, and for about 45 minutes of game time tortured the hell out of the fellow, leaving the still-living husk on the wharfside for his friends to find in the morning.

They seemed well satisfied in their retribution, and more was to come ...

Need a quick scenario?

One of my weapons is a magnificent book: the Funk & Wagnalls Standard Dictionary of Folklore, Mythology and Legend. Now I'm a folklorist generally, which is why I got the book, but I realized that it's a terrific tool for gaming. Alright, let me open the book to a random page, five times. I'm going to take the first motif listed on the second page revealed:

* Egg curing. This is a folk medicine technique wherein an uncooked egg is rubbed over the patient's naked body. If used to dissipate fever or evil curses, the malady is supposedly sucked into the egg, and it's then buried in a stream.  (I'd wager that it'd be bad to cook the egg and eat it.  Something might be made of that.)  If used for diagnostic purposes, the egg is split open and examined by a haruspex.

* Moonstone. An examination of the folkloric properties of moonstone; its divinatory properties, that in some cultures it brings good luck, that in others it brings terrible luck if it isn't your birthstone.

* Soul-bird. A bird born in the forest at the same moment an infant is born, and the fate of the one depends on the fate of the other.

* Lauma. The New Guinean belief that a soul leaves a man at death and has an independent existence thereafter, something that can also happen temporarily, causing illness in the living person.

* Eagle dance. An Indian dance mimicking an eagle's flight, often associated with weather or battle magic.

There. Anyone who can't whip up an evocative scenario incorporating all of those elements isn't trying hard.

(The book's out of print, but you can find it in abundance on Amazon for as low as $8.  That's less than you'd pay for a hamburger at a restaurant these days.  Heck, you can even find the 1949 edition for sale.)

Evil Deities? How come?

"I AM dark and evil!  Really!  Fear me!"

Forum D00d: "The one problem with D&D's presentation of gods was always to me - how the hell do the Evil Deities get worshippers? Why would anyone worship Cyric, for example? I admit that settings did somewhat try to explain that, but I always thought that either they should be granting simply more power to their priesthood/cultists (while usually, to keep the mechanical balance somewhat, they don't), or they should be enforced by sheer power."

Well, there are one of six possible explanations, presuming you don't just dismiss the concept of D&D "Good" vs "Evil" as the arrant bullshit it is:

* Did Hitler think he was evil? Did Stalin? Pol Pot? Almost surely not. Just because we have an OOC system mechanic -- or just because the winners write the histories -- that proclaims someone "evil" doesn't mean that they think of themselves that way.

* The dark gods will have their due. Failure to worship them will bring their anger down on the land, something that has been proven time and time again. The people in the pews might be trembling with fear, but they come nonetheless.  The dark gods need to be propitiated with sacrifice, with offerings ... or else.

* They attract the losers, the misfits, the powerless, the people with nowhere else to go, those who crave vengeance. The dark gods are real, everyone knows that. If you can't beat the ones who oppress and bully you, worship at the altar of someone who can.

* Factionalism is.  Of course power structures will develop around organized faiths, and power struggles revolve around them.  If my enemies are firmly entrenched in the local parishes of the white-light god, then what are my other options?

* Haven't we all seen decades worth of players commit all manner of bestial and violent acts, all in the ostensible name of "Lawful Good?" The light gods, they preach Good, and Truth, and Honor, and Love, but look at the depredations of their followers! Isn't it just a pack of lies after all? The dark gods, though ... sure, they might be "evil," and there might even be some justice to the charge, but at least they'll never lie to you. They're honest about who and what they are.

 * Finally, there's just plain inertia: people worship where their parents worshiped, and their grandparents, and THEIR grandparents, and they don't give it much thought.  Let's face it: how many people in the United States actually are Christians?  You know, genuinely follow the precepts that Jesus sets forth in the Bible, all of that?  How many people really love their neighbors as themselves?  How many really reject wealth in favor of heavenly values?  How many people really turn the other cheek?  As opposed to just doing whatever the hell they want?  No.  There's a vast number of people who just show up of a Sunday, parrot what they're told to parrot, pay lip service to that which is socially required, ostentatiously sport a cross or a religious medal, all because that's what's socially acceptable, because let's face it, open pagans or atheists don't get all that far in back-country Alabama.  

(I definitely had a smile for the guest minister who, in his sermon, set forth the distinction between the faith OF Jesus and the faith "naming" Jesus.  I definitely didn't for the WaPo article quoting a Missouri megachurch member as saying that of course the Ten Commandments only applied to "our kind."  It's long since been my contention that the worst nightmare of the religious right would be to find out that Jesus was real, on the ground that if the anti-war, anti-wealth, anti-violence, pro-lower class Jesus of the Bible truly was in charge, the Second Coming would kick off with the words "Did you think I didn't actually mean anything I said?"  But I digress.)

And really, why would a fantasy world be all that different?  There's only the one temple in town, to Gibil the volcano god.  They only burn one person alive a season, and they usually find a criminal or buy a slave for that.  Everyone attends, and no one really pays much attention to the ritual words of "May the world burn, and I shall hold the torch" everyone repeats at the weekly services.  (Certainly no one actually DOES go out and set their neighbors' buildings on fire!)  They leave behind their offerings of coin in the obsidian bowl, and go their way.

So You Want To Write These Things Yourself?

Don't hold your breath, gamewriter.

People have odd notions of pros in this hobby.  I’ve come across some startling fanboyism.  When I came to gaming forums in 2003, after an eight year hiatus from tabletop, a fellow proclaimed in one thread of the inerrant truths of Ryan Dancey’s proclamations, was shocked that I’d neither heard of nor was impressed by him, and that I couldn’t be much of a gamer if I didn’t Know Who He Was.  That no one else in the hobby in 1995 had heard of Dancey didn’t really penetrate the poster’s shell.

(I reflect, with amusement -- and some irony -- that the gamer of today wouldn't know who in the hell Dancey was either, because he pretty much never did anything after 2003.  But I digress.)

But that's because participants in this hobby place a huge, disproportionate importance on it  — it's the same syndrome that has SF conventioneers quivering in ecstasy at the mere sight of authors who didn’t crack the New York Times top one hundred best-seller list with the most popular books of their careers.   Some people just gasp in horror that the names of the Big Name Authors of the Games They Play aren't engraved in gold in the consciousnesses of every gamer alive, and it's natural to go on from there to assume that these people are figures of monumental importance and wealth.

Now this is in ignorance of what most game designers make; for my own part, I was a frequent guest in the modest two-bedroom suburban apartment of the president of a game company that had one of the most hugely touted supplements of the 1980s, and he made almost ZERO money from the hobby — the family income was based on his day job as an environmental services executive.  There might not be more than a couple dozen people who make decent livings as full-time game designers.  There might not be that many.

There’s probably a hundred times that many people who’ve been a semi-pro at some time in their gaming careers, which leads into another syndrome. What sports fan hasn't sat up in his chair and cursed the blunderings of the home team, insistent that the player or the coach is a bum, and that he could do better himself? This derives from the fact that a majority of the men and a growing number of the women in this country at one point in their youths held a baseball bat, kicked a soccer ball or threw a football. It isn't THAT hard, they think, and so they figure they know all about it.

In like fashion, many GMs write their own scenarios and adventures. They have a notion how it's done, and they then read a product and mutter, "I could do a better job."  Now very few of you have book authors as personal friends (counting people who’ve had genuine national releases from major publishing houses, my total is two) ... but gaming?  Eight published authors of GURPS products alone have been regular players of mine, or else I’ve played in their campaigns.  That figure more than doubles for writers for non-GURPS products, and we won't even discuss those I’ve played with in one-shots, playtests or convention runs.

Now maybe there's a preponderance of game authors in New England, but what's more likely is that there's a whole lot of them out there period, and chances that every one of you who is a veteran gamer has played with at least one. So you look across the dice at the Sunday afternoon run, and there's Joe Blow, who wrote a module for D&D and a few articles for Vampire, and you say to yourself, "Sheesh, he's not any better a gamer than I am. What makes HIM so special?"  The mere implication that he's making dollars from the hobby can either be resentment making, or fill you with the certitude that you can do it yourself.

Fair enough.  Just don’t expect riches.  For the great majority of us, selling a gaming product meant some nice pin money. One sale got me the down payment on a new economy car. Another paid for a modest vacation.  One (split four ways for the co-authors) bought me my books and materials for my last semester of college.  I’ve got a dozen RPG publishing credits, and all of the money I ever earned from gamewriting doesn’t total up to a single year’s worth of a full-time minimum wage job.

Beyond that ... every single gamebook I ever wrote came through connections.  I met the aforementioned game company president at the local gaming club; he’d just moved to the Boston area, and we’d both joined the same dice baseball league.  There was the game company president who had a serious crush on my first wife's college roommate (true story!).  There were the people who recognized my name from long-time writing in APAs.  I started writing for GURPS because the baseball-loving game president had received a courtesy copy of the playtest rules from Steve Jackson, Rich didn’t have particular interest but knew I was a TFT GM, and handed them over to me – that got my name on the radar and into the GURPS corebooks.

This is how a number of game companies winnow down the hordes of energetic wannabe writers. Few game companies – if any – have people reading through slush piles. They often have specific projects in mind, fitting into existing product lines, and as in any other creative field they'll hire someone they know (or someone vouched for by someone they know) over those newcomers. They are not at all interested in OJT, and expect professional efforts written to their exact requirements, submitted on or before the deadlines, no excuses.

Starting your own deal from scratch? It can be done, and we know of folks who've done it. Unfortunately, many of them already had capital they were willing to invest to print their stuff, convention hop to push their stuff, and keep the bills paid while they were trying. And for every indie success, there've been twenty small press failures, and fifty no one's ever heard of beyond the local college's gaming club.

(I've two anecdotes to illustrate the syndrome. The first is from the mid-80s.  The gaming club at UMass-Amherst had a fellow who designed a board game, called Dawn of Islam.  Sorta a Diplomacy/Risk style wargame with unbalanced sides; the Byzantine position was by far the strongest.  Except ... the Islamic player, early in the game, received four tokens called "Army of the Faithful" which were damn near invincible, and of course to conquer the rest of Europe he'd have to go through the Byzantine player first.  Very intriguing, very well designed, very engrossing, there was a session damn near every week.  Everyone said that the designer ought to get it published.  He never succeeded at it, and the only reason I know the guy's name at this remove -- Roger Adair -- was in asking clubbies of the era on Facebook a couple years back.  Roger's passed away now, and no doubt his marvelous game's been at the bottom of a landfill for a couple decades.)

(Second one is, well, me.  I started veering away from D&D very early, and getting very very variant indeed.  Typed up the result in 1981, brought it to UMass with me the next spring.  I was something of a nine-day wonder that spring semester, had more players than I knew what to do with ... either I was that good a GM or everyone else was that bad, eh.  That was the only semester I was at UMass, life events taking me back to Boston, but one of my players had a xerox of the system, and Tom was enough of a fanboy to GM it.  He was doing it years later, something I found out at a SF convention down the road.  Having moved on to TFT and GURPS by then, I inwardly winced that someone was still GMing that godawful melange, but gave belated permission, and furthermore got into Tom's hands a copy of my spell manuscript, the part he never had.  The last I'd heard, he was still GMing it deep into the 1990s, many years more than I'd ever stuck with it.  Go figure.)

Not deterred? Fair enough ... give it a shot! Just make sure to keep your day job.

Baiting and Switching ... Not.

So there was a thread once, where the OP put forth a proposition, based on indig tribes of Southeast Asia such as the Hmong or the Karen: that orcs were similarly folk who were pushed out of the better, nicer lands, who lived on the fringes of civilization as a matter of course, and who were far more stigmatized as Those Barbarians than anything else.  This wouldn’t be readily apparent to the players, who’d hold – and be expected to hold, as All Civilized Folk ought – the classic prejudices about orcs being nasty evil beings needing extermination.

The OP somewhat presciently said that this would either work well or piss everyone off, and it did: starting with other posters, who raked coals of fire over the idea.  The OP was accused of “cheating,” of having a “social agenda,” of baiting-and-switching, and of breaking the expected D&D paradigm.  One poster, rather colorfully, compared the “humiliation and embarrassment” of the situation to showing up at your boss' wedding in a clown suit.

This is not an unusual reaction in gaming circles ... IMHO, more because their own worldview was threatened than any other factor.  Now, yes: if the OP's was running straight D&D, with published dungeon modules fresh out of the shrink wrap, and advertised a hack-n-slash campaign, then yes, messing with people's (completely OOC) preconception of How You're Supposed To Be GMing Those Races is railroading.  I'm equally willing to acknowledge that a number of game systems have fixed settings with defined notions of the setting's races. A Pe Choi in Empire of the Petal Throne, a troll in RuneQuest, a dwarf in Warhammer, a gargun in Harnmaster, we have a good idea how they're to be portrayed.

For my own part? I think the notion of orcs as the fantasy world's 'Yards is a smashing one. Beyond that, I'm a GM. I get to set the standards for my setting. I can adopt whatever moral standards I bloody well feel like adopting, I get to define my world's orcs however I please, I am not bound by any fictional source or player expectation when I do it, and all the rest of you get to do the same around your own gaming tables.

Beyond that ... not everyone plays D&D 4th with a (say) Forgotten Worlds setting.

Let me repeat that: not everyone plays D&D.

Orcs are presented in different fashions in other systems. GURPS has its own take on them. Harn has its own take on them. Warcraft has its own take on them. Shadowrun has its own take on them. Warhammer has separate spins depending on whether you're doing Fantasy or 40,000. The claim that orcs are monolithically, irredeemably evil throughout the RPG world is flat out false ... and doesn't even apply to D&D, which has had orcs as playable PC races in more than one edition.

(And for pity's sake, in what universe is ANY race monolithically "anything" at all?  Do "humans" have a monolithic culture?)

The notion, therefore, that "changing" how orcs work in your campaign is by-definition a bait and switch is bullshit.

And when this is a "reveal," and the whole point is that the general perception of the world might be wrong ...? Err. This isn't an epic screwjob. This is a plot twist.

How To Do Your Own Age Of Sail

The Mayflower II, the only ship in this article I've ever been on.

To the verisimilitude fan, published RPG settings get a lot wrong.  I’ve ranted about this a fair bit, but there’s no example so stark and startling as how badly and consistently gamers get ships wrong.

You’re all gamers, and you know how seafaring in RPGs is depicted.  It’s right out of Hollywood movies of the 18th and 19th centuries, classic Age of Sail tech.  To a degree, this is understandable: medieval and Renaissance depictions of Arthurian and Biblical legends put folks in clothing, armor and weapons that would’ve fit in perfectly in contemporary culture.  Moreover, filmmakers have budgets, and cinematic ships are almost always drawn from the pool of replica Age of Sail vessels out there.

This is reflected in gaming: ships are often depicted as huge, with 19th century cannon, ship’s wheels, sleek keel:beam ratios and all the trappings of the Age of Sail.

But we do know a lot about those earlier vessels.  Want to do it right?  Ditch damn near every movie you saw.

* First off, ocean-going medieval vessels are small.  The largest of them topped out at 200 tons, their accommodations could charitably be described as “spartan,” and they weren’t overwhelmingly seaworthy.  They didn’t hold that many sailors, nor that many provisions – the navigational standard was to coast hop.  Check out some of these links for examples of cogs, and carracks, caravels and fluyts that replaced them in the late Middle Ages and Renaissance eras.  Take the Mayflower II above, a Renaissance-era fluyt.  Being a Plymouth-area native, I've been aboard her several times.  Imagining over a hundred passengers AND their livestock AND their stuff AND the crew on that teensy vessel, for two months yet in the North Atlantic autumn, just blows my mind.

* Secondly, the science of shipbuilding hadn’t evolved very far.  The fad for medieval European shipbuilding was for very high “castles” both fore and aft, quite suitable for the boarding tactics of the time and reminiscent of land fortifications, and which survives in the nomenclature of today’s “forecastle.”  As cannon became common, they got jammed onto these top-heavy ships in appalling numbers and in appalling sizes – stability calculations being centuries in the future – and as you can imagine, an all-too-frequent occurrence was overburdened ships just toppling over and sinking on the spot.  They were not all that seaworthy, and even with celebrated mariners like the Vikings, it's estimated that a full 25% of voyages out of the sight of land resulted in ship losses.

* Thirdly, they were a lot fatter than you imagine.  Remember that ship deck plan you downloaded from that gaming site?  It’s almost certainly crap.  The keel:beam ratio (translation for you landlubbers: how long it is vs. how wide it is) runs as much as 7:1, which is about what you expect for 1870s extreme clippers that couldn’t possibly carry armament or a military crew and could do only one thing well – sail in a straight line, very very fast.  I don’t say it isn’t useful to the designers of gamebooks, who can jam three grid plans of a 7:1 ship onto a single sheet of paper.  It just bears no resemblance to reality.

The ratio for medieval ships were much more often along the lines of 3:1, and even as chubby as 2.5:1.  This made for a craft that could haul more cargo, and could handle rough seas better, but it doesn’t look very 19th century.

* Fourthly, a number of innovations hadn’t yet been invented.  Smaller ships (such as cogs) were steered with tillers, just as you’d see on modern-day pleasure boats, or with large and inefficient steering oars.  This didn’t work very well when ship sizes grew, and the whipstaff was invented – only in the 16th century.  (The modern day ship’s wheel wasn’t invented until the 18th century.)  The familiar anchor shape you think of wasn’t invented until well into the 1800s: medieval anchors didn’t have shanks, and the arms were straight instead of curved.  Stern-mounted rudders weren’t common until well into the Middle Ages.  Teredo worms, barnacles and seaweed made short work of hulls, and a 30 year old ship was an old one.  (It took until the 1780s to work out the kinks of copper bottoming, and even there it upped the price of a ship hull SIXFOLD -- only the British Navy gave it a serious go.)

(By the bye, all of this refers to European seafaring, with which players are likely to prefer for aesthetic reasons.  Chinese and Arabic seafaring of medieval times were much more advanced.  South Asian shipbuilding had access to woods like teak, with superior resistance to rot.)

I’ll touch on pirate ships, a major topic of gaming sail.  Contrary to popular belief, there isn't a particular ship design called "pirate ship." Pirates used just about any hull they could get their hands on, although they favored sloops for their maneuverability, speed and ease of repair.  Far more often than otherwise, these ships were usually small.  This flies in the face of Hollywood, which favors large replica vessels and broad decks onto which you can pack a satisfyingly large cinematic battle as well as cameras and tech crew, but there you have it. 

As to that, Spanish treasure galleons were very seldom used as pirate vessels; they could pack a whopping lot of men, but they were ponderously slow and needed outright shipyards for maintenance, something unavailable to most pirates. When galleons were used by pirates were in full scale assaults by outright fleets, more along the line of amphibious invasions than the normal run of piracy, and those assaults were things of legend that happened once or twice a decade.

Deckplans?  That’d be a bit of a problem.  NO library will have deckplans for a 17th century ship or earlier smaller than a third-rate -- about the size and armament of a USS Constitution-sized heavy frigate -- for that matter: the earliest sloop deck plan that has been uncovered so far dates from 1717.  (If by some miracle you have a genuine deck plan for an earlier ship, Mystic Seaport researchers would love to talk to you.)

A book I own and strongly recommend is Deane's Doctrine of Naval Architecture, published by the Naval Institute Press. Sir Anthony Deane was a prominent naval shipwright of the 17th century, and the Doctrine was written at the request of his patron, Samuel Pepys (the famous diarist, who was at the time the First Lord of the Admiralty), to explain ship design and building to the educated layman.  Peyps was hoping to better inform the Parliamentarians of the day of the price of admiralty, y'see ...

Among other things, the book has exhaustive statistics of every ship on the Royal Navy list in 1670, and I mean exhaustive – I can crack the book open and give you for every possible rate (and where listed, for each one of the ships in the Royal Navy) the length and number of every single scrap of rigging, how much it cost to completely rig or provision the ship, how many guns and anchors they had, every possible dimension ... to a degree that would blow the mind of the most anal dungeonmapper alive.

In particular, using Deane's stats and given the range of guns found on pirate ships of the day, the heaviest pirate ships would be around 90' by the keel and 28-29' by the beam (for a 40-gun ship that could man around 200 men), and generally getting no smaller than a 4-gun smack that could man about 30 men and measure around 44' by the keel and 11-12' by the beam.
