SAIL(6) Games Manual SAIL(6)
NAME
sail - multi-user wooden ships and iron men
SYNOPSIS
sail [-bx] [-s [-l]] [num]
DESCRIPTION
sail is a computer version of Avalon Hill's game of fighting sail
originally developed by S. Craig Taylor.
Players of sail take command of an old-fashioned Man of War and fight
other players or the computer. They may re-enact one of the many
historical sea battles recorded in the game, or they can choose a
fictional battle.
As a sea captain in the Sail Navy, the player has complete control over
the workings of his ship. He must order every maneuver, change the set
of his sails, and judge the right moment to let loose the terrible
destruction of his broadsides. In addition to fighting the enemy, he
must harness the powers of the wind and sea to make them work for him.
The outcome of many battles during the age of sail was decided by the
ability of one captain to hold the `weather gage'.
The flags are:
-b No bells.
-l Show the login name. Only effective with -s.
-s Print the names and ships of the top ten sailors.
-x Play the first available ship instead of prompting for a choice.
IMPLEMENTATION
sail is a multiplayer game. Each player runs sail to either connect to
an existing game or start a new one. The game server (or "driver") is an
extra fork of the sail program created when a game is started. The
driver coordinates the game and runs the computer ships.
If a player joins a game in progress, a synchronization process occurs (a
rather slow process for everyone), and then the game continues.
Note that while each scenario can be running independently with different
players, each scenario can also only be running once at any given time.
COMMUNICATION
To implement a multi-user game in Version 7 UNIX, which was the operating
system sail was first written under, the communicating processes must use
a common temporary file as a place to read and write messages. For e.g.
scenario 21, this file is /var/games/sail/#sailsink.21. Corresponding
file names are used for the other scenarios.
In addition, a locking mechanism must be provided to ensure exclusive
access to the shared file. sail uses a technique stolen from an old game
called "pubcaves" by Jeff Cohen. Processes do a busy wait in the loop
for (n = 0; link(sync_file, sync_lock) < 0 && n < 30; n++)
sleep(2);
until they are able to create a hard link named e.g.
/var/games/sail/#saillock.21. where 21 is again the scenario number.
Since creating a hard link is atomic, a process where this succeeds will
have exclusive access to the temporary file.
CONSEQUENCES OF SEPARATE PLAYER AND DRIVER PROCESSES
When players do something of global interest, such as moving or firing,
the driver must coordinate the action with the other ships in the game.
For example, if a player wants to move in a certain direction, he writes
a message into the temporary file requesting the driver to move his ship.
Each "turn", the driver reads all the messages sent from the players and
decides what happened. It then writes back into the temporary file new
values of variables, etc.
The most noticeable effect this communication has on the game is the
delay in moving. Suppose a player types a move for his ship and hits
return. What happens then? The player process saves up messages to be
written to the temporary file in a buffer. Every 7 seconds or so, the
player process gets exclusive access to the temporary file and writes out
its buffer to the file. The driver, running asynchronously, must read in
the movement command, process it, and write out the results. This takes
two exclusive accesses to the temporary file. Finally, when the player
process gets around to doing another 7-second update, the results of the
move are displayed on the screen. Hence, every movement requires four
exclusive accesses to the temporary file (anywhere from 7 to 21 seconds
depending upon asynchrony) before the player sees the results of his
moves.
In practice, the delays are not as annoying as they would appear. There
is room for "pipelining" in the movement. After the player writes out a
first movement message, a second movement command can then be issued.
The first message will be in the temporary file waiting for the driver,
and the second will be in the file buffer waiting to be written to the
file. Thus, by always typing moves a turn ahead of the time, the player
can sail around quite quickly.
If the player types several movement commands between two 7-second
updates, only the last movement command typed will be seen by the driver.
Movement commands within the same update "overwrite" each other, in a
sense.
DEFECTS OF THIS SYSTEM IN THE MODERN WORLD
Quite a few.
It should be thrown out and replaced with something socket-based.
HISTORICAL INFO
Old square-riggers were very maneuverable ships capable of intricate
sailing. Their only disadvantage was an inability to sail very close to
the wind. The design of a wooden ship allowed for the guns to bear only
to the left and right sides. A few guns of small aspect (usually 6 or 9
pounders) could point forward, but their effect was small compared to a
68 gun broadside of 24- or 32-pounders. The guns bear approximately like
so:
\
b----------------
---0
\
\
\ up to a range of ten (for round shot)
\
\
\
Firing a broadside into a ship lengthwise, from bow to stern or stern to
bow, is called raking. This did a great deal more damage, because the
shot tended to bounce along the deck. Because the bows of a ship are
very strong and present a smaller target than the stern, a stern rake
(firing from the stern to the bow) causes more damage than a bow rake.
b
00 ---- Stern rake!
a
Most ships were equipped with carronades, which were very large, close
range cannons. American ships from the revolution until the War of 1812
were almost entirely armed with carronades.
The period of history covered in sail is approximately from the 1770's
until the end of Napoleonic France in 1815. There are many excellent
books about the age of sail. (See REFERENCES).
Fighting ships came in several sizes classed by armament. The mainstays
of any fleet were its ships of the line, or line of battle ships. These
were so named because in fleet actions they would sail in lines so as to
present all broadsides to the enemy at once. The modern terms "ocean
liner", and "battleship" are derived from "ship of the line".
The pride of the fleet were the "first-rates". These were huge three
decked ships of the line mounting 80 to 136 guns. The guns in the three
tiers were usually 18, 24, and 32 pounders in that order from top to
bottom.
Lesser ships were known as "second-rates", "third-rates", and even
"fourth-rates". The most common size was the 74 gun two-decked ship of
the line. The two gun decks usually mounted 18 and 24 pounder guns.
Razees were ships of the line with one deck sawed off. These mounted
40-64 guns and were a poor cross between a frigate and a line of battle
ship. They neither had the speed of the former nor the firepower of the
latter.
The next class was the frigate. Often called the "eyes of the fleet",
frigates came in many sizes mounting anywhere from 32 to 44 guns. These
were very handy vessels. They could outsail anything bigger and outshoot
anything smaller. Frigates did not generally fight in lines of battle as
the much bigger 74s did. Instead, they were sent on individual missions
or in small groups to harass the enemy's rear or capture crippled ships.
They were much more useful this way, in missions away from the fleet.
They could hit hard and get away fast.
Lastly, there were the corvettes, sloops, and brigs. These were smaller
ships mounting typically fewer than 20 guns. A corvette was only
slightly smaller than a frigate, so one might have up to 30 guns. Sloops
were used for carrying despatches or passengers. Brigs were small
vessels typically built for land-locked lakes.
SAIL PARTICULARS
Ships in sail are represented on the screen by two characters. One
character represents the bow of the ship, and the other represents the
stern. Ships have nationalities and numbers. The first ship of a
nationality is number 0, the second number 1, etc. Therefore, the first
British ship in a game would be printed as "b0". The second Brit would
be "b1", and the fifth Don would be "s4".
Ships can set normal sails, called Battle Sails, or bend on extra canvas
called Full Sails. A ship under full sail is a beautiful sight indeed,
and it can move much faster than a ship under battle sails. The only
trouble is, with full sails set, there is so much tension on sail and
rigging that a well aimed round shot can burst a sail into ribbons where
it would only cause a little hole in a loose sail. For this reason,
rigging damage is doubled on a ship with full sails set. This does not
mean that full sails should never be used; the author recommends keeping
them up right into the heat of battle. When a ship has full sails set,
the letter for its nationality is capitalized. E.g., a Frog, "f0", with
full sails set would be printed as "F0".
When a ship is battered into a listing hulk, the last man aboard strikes
the colors. This ceremony is the ship's formal surrender. The
nationality character of a surrendered ship is printed as `!'. E.g., the
Frog of our last example would soon be "!0".
A ship that reaches this point has a chance of catching fire or sinking.
A sinking ship has a `~' printed for its nationality, and a ship on fire
and about to explode has a `#' printed.
Ships that have struck can be captured; captured ships become the
nationality of the prize crew. Therefore, if an American ship captures a
British ship, the British ship will thenceforth have an `a' printed for
its nationality. In addition, the ship number is changed to one of the
characters `&'()*+' corresponding to its original number `012345'. E.g.,
the "b0" captured by an American becomes the "a&". The "s4" captured by
a Frog becomes the "f*".
The ultimate example is, of course, an exploding Brit captured by an
American: "#&".
MOVEMENT
Movement is the most confusing part of sail to many. Ships can head in 8
directions:
0 0 0
b b b0 b b b 0b b
0 0 0
The stern of a ship moves when it turns. The bow remains stationary.
Ships can always turn, regardless of the wind (unless they are becalmed).
All ships drift when they lose headway. If a ship doesn't move forward
at all for two turns, it will begin to drift. If a ship has begun to
drift, then it must move forward before it turns, if it plans to do more
than make a right or left turn, which is always possible.
Movement commands to sail are a string of forward moves and turns. An
example is "l3". It will turn a ship left and then move it ahead 3
spaces. In the drawing above, the "b0" made 7 successive left turns.
When sail prompts you for a move, it prints three characters of import.
E.g.,
move (7, 4):
The first number is the maximum number of moves you can make, including
turns. The second number is the maximum number of turns you can make.
Between the numbers is sometimes printed a quote ('). If the quote is
present, it means that your ship has been drifting, and you must move
ahead to regain headway before you turn (see note above). Some of the
possible moves for the example above are as follows:
move (7, 4): 7
move (7, 4): 1
move (7, 4): d /* drift, or do nothing */
move (7, 4): 6r
move (7, 4): 5r1
move (7, 4): 4r1r
move (7, 4): l1r1r2
move (7, 4): 1r1r1r1
Because square riggers performed so poorly sailing into the wind, if at
any point in a movement command you turn into the wind, the movement
stops there. E.g.,
move (7, 4): l1l4
Movement Error;
Helm: l1l
Moreover, upon making a turn, the movement allowance drops to the lesser
of what remains this turn and what would be available when going in the
new direction. Thus, any turn closer to the wind will generally preclude
sailing the full distance printed in the "move" prompt.
Old sailing captains had to keep an eye constantly on the wind. Captains
in sail are no different. A ship's ability to move depends on its
attitude to the wind. The best angle possible is to have the wind off
your quarter, that is, just off the stern. The direction rose on the
side of the screen gives the possible movements for your ship at all
positions to the wind. Battle sail speeds are given first, and full sail
speeds are given in parenthesis.
0 1(2)
\|/
-^-3(6)
/|\
| 4(7)
3(6)
Pretend the bow of your ship (the "^") is pointing upward and the wind is
blowing from the bottom to the top of the page. The numbers at the
bottom "3(6)" will be your speed under battle or full sails in such a
situation. If the wind is off your quarter, then you can move "4(7)".
If the wind is off your beam, "3(6)". If the wind is off your bow, then
you can only move "1(2)". Facing into the wind, you cannot move at all.
Ships facing into the wind are said to be in irons.
WINDSPEED AND DIRECTION
The windspeed and direction is displayed as a weather vane on the side of
the screen. The number in the middle of the vane indicates the wind
speed, and the + to - indicates the wind direction. The wind blows from
the + sign (high pressure) to the - sign (low pressure). E.g.,
|
3
+
The wind speeds are:
0 becalmed
1 light breeze
2 moderate breeze
3 fresh breeze
4 strong breeze
5 gale
6 full gale
7 hurricane
If a hurricane shows up, all ships are destroyed.
GRAPPLING AND FOULING
If two ships collide, they run the risk of becoming tangled together.
This is called fouling. Fouled ships are stuck together, and neither can
move. They can unfoul each other if they want to. Boarding parties can
only be sent across to ships when the antagonists are either fouled or
grappled.
Ships can grapple each other by throwing grapnels into the rigging of the
other.
The number of fouls and grapples you have are displayed on the upper
right of the screen.
BOARDING
Boarding was a very costly venture in terms of human life. Boarding
parties may be formed in sail to either board an enemy ship or to defend
your own ship against attack. Men organized as Defensive Boarding
Parties fight twice as hard to save their ship as men left unorganized.
The boarding strength of a crew depends upon its quality and upon the
number of men sent.
CREW QUALITY
The British seaman was world renowned for his sailing abilities.
American sailors, however, were actually the best seamen in the world.
Because the American Navy offered twice the wages of the Royal Navy,
British seamen who liked the sea defected to America by the thousands.
In sail, crew quality is quantized into 5 energy levels. Elite crews can
outshoot and outfight all other sailors. Crack crews are next. Mundane
crews are average, and Green and Mutinous crews are below average. A
good rule of thumb is that Crack or Elite crews get one extra hit per
broadside compared to Mundane crews. Don't expect too much from Green
crews.
BROADSIDES
Your two broadsides may be loaded with four kinds of shot: grape, chain,
round, and double. You have guns and carronades in both the port and
starboard batteries. Carronades only have a range of two, so you have to
get in close to be able to fire them. You have the choice of firing at
the hull or rigging of another ship. If the range of the ship is greater
than 6, then you may only shoot at the rigging.
The types of shot and their advantages are:
ROUND Range of 10. Good for hull or rigging hits.
DOUBLE Range of 1. Extra good for hull or rigging hits. Double takes
two turns to load.
CHAIN Range of 3. Excellent for tearing down rigging. Cannot damage
hull or guns, though.
GRAPE Range of 1. Sometimes devastating against enemy crews.
On the side of the screen is displayed some vital information about your
ship:
Load D! R!
Hull 9
Crew 4 4 2
Guns 4 4
Carr 2 2
Rigg 5 5 5 5
"Load" shows what your port (left) and starboard (right) broadsides are
loaded with. A `!' after the type of shot indicates that it is an
initial broadside. Initial broadside were loaded with care before battle
and before the decks ran red with blood. As a consequence, initial
broadsides are a little more effective than broadsides loaded later. A
`*' after the type of shot indicates that the gun crews are still loading
it, and you cannot fire yet. "Hull" shows how much hull you have left.
"Crew" shows your three sections of crew. As your crew dies off, your
ability to fire decreases. "Guns" and "Carr" show your port and
starboard guns. As you lose guns, your ability to fire decreases.
"Rigg" shows how much rigging you have on your 3 or 4 masts. As rigging
is shot away, you lose mobility.
EFFECTIVENESS OF FIRE
It is very dramatic when a ship fires its thunderous broadsides, but the
mere opportunity to fire them does not guarantee any hits. Many factors
influence the destructive force of a broadside. First of all, and the
chief factor, is distance. It is harder to hit a ship at range ten than
it is to hit one sloshing alongside. Next is raking. Raking fire, as
mentioned before, can sometimes dismast a ship at range ten. Next, crew
size and quality affects the damage done by a broadside. The number of
guns firing also bears on the point, so to speak. Lastly, weather
affects the accuracy of a broadside. If the seas are high (5 or 6), then
the lower gunports of ships of the line can't even be opened to run out
the guns. This gives frigates and other flush decked vessels an
advantage in a storm. The scenario Pellew vs. The Droits de L'Homme
takes advantage of this peculiar circumstance.
REPAIRS
Repairs may be made to your Hull, Guns, and Rigging at the slow rate of
two points per three turns. The message "Repairs Completed" will be
printed if no more repairs can be made.
PECULIARITIES OF COMPUTER SHIPS
Computer ships in sail follow all the rules above with a few exceptions.
Computer ships never repair damage. If they did, the players could never
beat them. They play well enough as it is. As a consolation, the
computer ships can fire double shot every turn. That fluke is a good
reason to keep your distance. The driver figures out the moves of the
computer ships. It computes them with a typical A.I. distance function
and a depth first search to find the maximum "score". It seems to work
fairly well, although I'll be the first to admit it isn't perfect.

HISTORY
Dave Riggle wrote the first version of sail on a PDP-11/70 in the fall of
1980. Needless to say, the code was horrendous, not portable in any
sense of the word, and didn't work. The program was not very modular and
had fseek(3) and fwrite(3) calls every few lines. After a tremendous
rewrite from the top down, the first working version was up and running
by 1981. There were several annoying bugs concerning firing broadsides
and finding angles.
Ed Wang rewrote the angle() routine in 1981 to be more correct. He also
added code to let a player select which ship he wanted at the start of
the game, instead of always taking the first one available.
Captain Happy (Craig Leres) is responsible for making sail portable for
the first time. This was no easy task. Constants like 2 and 10 were
very frequent in the code. The sail code was also notorious for the use
of "Riggle Memorial Structures". Many structure references were so long
that they ran off the line printer page. Here is an example, if you
promise not to laugh:
specs[scene[flog.fgamenum].ship[flog.fshipnum].shipnum].pts
sail received its fourth and most thorough rewrite in the summer and fall
of 1983. Ed Wang rewrote and modularized the code (a monumental feat)
almost from scratch. Although he introduced many new bugs, the final
result was very much cleaner and (?) faster. He added window movement
commands and find ship commands.
At some currently unknown time, sail was imported into BSD.
