SAIL(6) Games Manual SAIL(6) NAME sail -- multi-user wooden ships and iron men SYNOPSIS sail [-bx] [-s [-l]] [number] DESCRIPTION sail is a computer version of Avalon Hill's game of fighting sail orig- inally 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 his- torical sea battles recorded in the game, or they can choose a fic- tional 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 de- struction 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 really two programs in one. Each player starts up a process which runs his own ship. In addition, a driver process is forked (by the first player) to run the computer ships and take care of global bookkeeping. Because the driver must calculate moves for each ship it controls, the more ships the computer is playing, the slower the game will appear. If a player joins a game in progress, he will synchronize with the other players (a rather slow process for everyone), and then he may play along with the rest. To implement a multi-user game in Unix Version 7, which was the operat- ing system sail was first written under, the communicating processes must use a common temporary file as a place to read and write messages. In addition, a locking mechanism must be provided to ensure exclusive access to the shared file. For example, sail uses a temporary file named /tmp/#sailsink.21 for scenario 21, and corresponding file names for the other scenarios. To provide exclusive access to the temporary 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) == -1 && n < 30; n++) sleep(2); until they are able to create a link to a file named /tmp/#saillock.??. The "??" correspond to the scenario number of the game. Since Unix guarantees that a link will point to only one file, the process that succeeds in linking 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 that the driver 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 re- sults 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 up- dates, only the last movement command typed will be seen by the driver. Movement commands within the same update "overwrite" each other, in a sense. 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 only for the guns to bear 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 com- pared to a 68-gun broadside of 24 or 32 pounders. The guns bear ap- proximately like so: \ b---------------- ---0 \ \ \ up to a range of ten (for round shot) \ \ \ An interesting phenomenon occurred when a broadside was fired down the length of an enemy ship. The shot tended to bounce along the deck and did several times more damage. This phenomenon was called a rake. Be- cause 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 1770s 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 main- stays of any fleet were its "Ships of the Line", or "Line of Battle Ships". They were so named because these ships fought together in great lines. They were close enough for mutual support, yet every ship could fire both its broadsides. 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. 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. The guns in the three tiers were usually 18, 24, and 32 pounders in that order from top to bottom. Various other ships came next. They were almost all "razees", or ships of the line with one deck sawed off. They 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. Next came the "eyes of the fleet". Frigates came in many sizes mount- ing anywhere from 32 to 44 guns. They were very handy vessels. They could outsail anything bigger and outshoot anything smaller. Frigates didn't fight in lines of battle as the much bigger 74's did. Instead, they harassed the enemy's rear or captured crippled ships. They were much more useful in missions away from the fleet, such as cutting out expeditions or boat actions. 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 dispatches or passengers. Brigs were something you built for land-locked lakes. SAIL PARTICULARS Ships in sail are represented by two characters. One character repre- sents 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 can- vas called Full Sails. A ship under full sail is a beautiful sight in- deed, 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 rea- son, rigging damage is doubled on a ship with full sails set. Don't let that discourage you from using full sails: I like to keep them up right into the heat of battle. A ship with full sails set has a capi- tal letter for its nationality. 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 has a random chance of catching fire or sinking when it reaches the stage of listing hulk. A sinking ship has a tilde `~' printed for its nationality, and a ship on fire and about to explode has a `#' printed. Captured ships become the nationality of the prize crew. Therefore, if an American ship captures a British ship, the British ship will have an `a' printed for its nationality. In addition, the ship number is changed to `&', `'', `(', `)', `*', or `+' depending upon the original number, be it 0, 1, 2, 3, 4, or 5. E.g., the `b0' captured by an Amer- ican 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 be- calmed). 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 possi- ble. 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, whenever you make a turn, your movement allowance drops to the lesser of what's left or what you would have at the new attitude. In short, if you turn closer to the wind, you most likely won't be able to sail the full allowance printed in the "move" prompt. Old sailing captains had to keep an eye constantly on the wind. Cap- tains 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 parentheses. 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)'. If you are facing into the wind, you can't move at all; ships facing into the wind were said to be "in irons". WINDSPEED AND DIRECTION The windspeed and direction is displayed as a little 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 par- ties 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 de- fend 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. Amer- ican sailors, however, were actually the best seamen in the world. Be- cause 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 aver- age. 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 dam- age 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 ini- tial 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 load- ing 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 rig- ging 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 excep- tions. Computer ships never repair damage. If they did, the players could never beat them. They play well enough as it is. As a consola- tion, 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. dis- tance function and a depth-first search to find the maximum "score". It seems to work fairly well, although it isn't perfect. HOW TO PLAY Commands are given to sail by typing a single character. You will then be prompted for further input.

Needless to say, says Dave, 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()s and fwrite()s every few lines. After a tremendous rewrite from the top down, he got the first working ver- sion up by 1981. There were several annoying bugs concerning firing broadsides and finding angles. sail uses no floating point, by the way, so the direction routines are rather tricky. Ed Wang rewrote the angle() routine in 1981 to be less incorrect, and he added code to let a player select which ship he wanted at the start of the game. Captain Happy (Craig Leres) is responsible for making sail portable for the first time. This was no easy task, by the way. 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. AUTHORS sail has been a group effort.
