1) Conduct Movement — Both sides move their ships. All movement is conducted simultaneously, and players must avoid watching other players move first before then moving their own vessels. An alternative is to roll dice, with the high roller moving first. This may be done once at the start of the game or at the start of each turn.

2) First Gunnery — Both sides declare targets and resolve gunnery. The same side should always resolve gunnery first in order to speed game play. All damage within this phase is consider simultaneous, so the order in which gunnery is resolved does not give any advantage. Damage inflicted during this gunnery phase becomes effective at the end of this phase (phase two) and before the start of phase three. This means that any losses suffered during the first gunnery phase reduces ship effectiveness for the second gunnery and torpedo phase (phase three).

3) Second Gunnery & Torpedo Fire — Ships which failed the ROF die roll in the first gunnery round may attempt to fire again, with both sides declaring targets and resolving gunnery in the same way. Any torpedo attacks are then resolved in the same manner. As with Phase 2, all damage - both gunnery and torpedo - within this phase is also considered simultaneous. Note that torpedo fire may only occur in this phase. Remember that any damage which occurred in the previous gunnery phase will have taken effect before starting this phase. Ships which successfully fired in the first gunnery round (i.e., passed the ROF roll) may not fire in this round, even if they only failed to score on the gunnery die roll.

4) Recurring Hits — All ships with fires burning on board (Active F Hits) must roll for automatic fire effects on the Damage table. If the fire goes out (the "out" result), cross-out or erase the "F" mark in that ship's Blast Hits box. If there are explosions, resolve their results immediately. All ships with any SX Hits must roll for additional SX Hit occurrence on the Damage Table. On a roll of 11 or 12, add another unrepairable speed hit (SX Hit) to that ship's speed boxes.

5) Repair Attempts — Players may attempt repairs to their vessels by rolling on the Damage table. See 4.2 Damage Repair.

6) Check for Sinking — Any ships with all speed boxes crossed out due to SX Hits must roll for sinking on the Sinking table. See 4.3 Sinking.

« 2.0 MOVEMENT
The maximum distance a ship may move each turn is limited by the number shown in the topmost undamaged speed box on that vessel's ship log (Crossed out speed boxes do not count toward available speed). A ship may move less than the maximum available, and it may change its speed (distance moved) depending on the amount it moved on the previous turn. The distance moved should be measured from the front edge of the ship using a tape measure or scale. Ships may move through each other but may not end their move "stacked" or otherwise occupying the same space unless forced by involuntary conditions (Example: Vessel with a D Hit passing through a ship with zero movement, etc.). In such cases, the moving ship should stop slightly short of being on top of the other model, but can remain with bases (if any) overlapping. Models mounted on bases may end their turn with the bases slightly and temporarily overlapping, but that should be a passing condition that is not taken to excess.

Example: Using the Medium scale, the British battleship HMS Hannibal has an original maximum speed of 6-inches. Using the eighth speed box (top-left on ship log which would be showing 6.0"), she can turn a maximum of 45° once for free during any one turn. If she turns twice, her maximum distance moved will be 5¼-inch and the two turn pivots should be separated by ¾-inch of movement. If she moves 3-inches (using her fourth speed box) she would be able to turn 90° during any one pivot. If for some reason her speed for the turn is using her first speed box (bottom-right on ship log which would be showing ¾-inch) her maximum turn would be 0°, meaning that she does not have enough steerageway to make normal turns.

1) Take note of the firing ship's ROF Rating, it is the number needed on the black ROF die.
2) Declare the firing ship's target and the Gunnery Rating (Heavy, Light or both) to be used against it.
3) Compare the firing ship's Gunnery Rating to the target's corresponding Armor Rating and establish the percentage difference between the two.
4) Roll both firing dice and establish: a) Whether the ROF die result let the ship fire per the ROF table and; b) Whether the Gunnery dice resulted in any G or S hits on the Battery Fire Table.
5) Record the resulting hit(s) in the ship's log and total the values of both dice to see if any Blast Damage occurred.
6) If any Blast Damage did occur, record it in the Blast Damage box in the ship's log and/or immediately resolve the damage in the Damage Table.

ROF Die Roll Modifiers
Missed last ROF roll - Subtract one (-1) from the die roll if the ship's last ROF roll failed to let the ship fire. Applies either to attempts made this turn or on the previous turn (i.e., maximum benefit for this modifier is -1).

Long Range: A ship firing into the long range bracket may only use its Heavy Gunnery Rating to resolve battery fire.
Medium Range: A ship firing into the medium range bracket may fire both its Heavy and Light Gunnery Ratings, with the Heavy Gunnery Rating counting against the Heavy Armor of the target, and the Light Gunnery Rating counting against the Light Armor of the target. Ships may fire their heavy and light gunnery at two different targets, or both at one target. The recommended method is for the Heavy and Light Gunnery to be resolved as two different die rolls, although players can also resolve both attacks off of a single die roll. This tends to give "mirror" results that lack variety.
Point-Blank Range: As with medium range, both Heavy and Light Gunnery may take place. Boat guns may also be used at point-blank range, but only within the target size limits imposed by the rules. Boat guns cannot fire beyond point-blank range.

Example: A ship with a Heavy Gunnery value of 18 fires on a target with 12 armor points. The attacker will use the 150 line (meaning 150%), which needs to roll a 1 though 5 on the die to score one hit, or a 6 through 10 to score two hits.. If the player rolls an 8, they will score the two hits, with the first hit being an S Hit, and therefore the second hit being a G Hit. If they roll a 5, a single G Hit would be scored. The alternating of hits only really matters when three hits are scored; in such cases players will see two of one hit type and one of the other type scored (G,S,G, or S,G,S).

Example: The Japanese battleship Mikasa is conducting long range Heavy Fire at the Russian battleship Borodino. The Mikasa player's fire die roll is 5, 8. The black die roll of 5 means that the Mikasa did fire this turn because its heavy ROF rating is a 7 and it rolled equal-to or less-than that number. The Mikasa's heavy gunnery rating is a 20 and the Borodino's heavy armor rating is a 10. This means that the Mikasa is using the 200% Gun/Armor column, with any die results between 5 and 9 resulting in two hits, so Mikasa scores two hits; the first is an S Hit (because of the 8 being an even number) and the second hit alternates to a G Hit. Had Mikasa rolled a 5, 11, she would have scored two G Hits and one S Hit on the Borodino. Her die results were too high to score any Blast Damage hits.

Torpedo Hit Die Roll Modifiers
Converging Target - Subtract one (-1) from the die roll if the courses of the firing ship and the target ship are converging (moving toward each other in any way). Even "almost parallel" courses in which the two ships are aligned slightly away from each other are not converging.
Static Target - Subtract one (-1) from the die roll if the target ship is not moving. A target ship is considered moving if it used two or more speed boxes worth of movement during the current game turn.
Destroyer/TB Firing - Subtract one (-1) from the die roll if the firing ship (boat) is a destroyer or torpedo boat. If small enough and fast enough, torpedo gunboats may count.

« 4.0 DAMAGE
As a ship suffers damage during the game, players will mark it on the ship log according to the type of damage inflicted. It is usually best to mark damage as a single slash until after both sides have fired, then fully cross out existing slash marks to show full loss. In cases where boxes – such as speed boxes – are marked off, this method works especially well, where players can mark small Xs next to the speed values. In cases where damage is the result of Blast Damage, players might not mark off a box, they may instead need to mark the blast damage code in the Blast Hits box on the ship log. This will happen with such damage codes as F (fire) and D (direction hit). It will usually be obvious whether the player should add a code to the blast damage box or simply cross something out.

« 4.1 Damage Types
Most of the Quickfire combat chart tables contain abbreviation codes for battle damage. Each of these damage codes tracks a very specific damage type. The glossary below offers definitions of all damage codes. Immediately following are guidelines for recording the various damage types. If a certain type of damage is called for on a vessel and there is no feature of that type on board, then the hit is counted as no effect unless otherwise called for by the nature of the hit in question.

« 4.2 Damage Repair
Each turn after active fires and SX hits have been checked (See Turn Sequence), players may attempt to repair Gunnery, Speed, Direction and Boat Gun hits. The ship's repair rating listed in the ship log's Repair box shows how many repair dice a player has available to use. A repair roll is conducted by rolling one twelve-sided die (1D12) and referring to the Damage table on the combat chart. Repair rolls that do not succeed in making an actual repair may be kept and reused on future turns (e.g., a failed attempt does not reduce the ship's repair point total). A repair roll which succeeds in making a repair is "used up," and the current repair point total for that ship is reduced by one. A player may use one repair die roll attempt against each damage point type, each turn. For example, if a ship has suffered three Light Gunnery hits, one repair die roll attempt on that Gunnery Rating may be made that repair phase. So in theory, if a ship takes one each Heavy Gunnery Hit, Light Gunnery Hit, Speed Hit and Boat Gun Hit, the player could be allowed to roll four repair dice that turn. Ships may not transfer repair points to other ships or conduct repairs on their behalf.

S+P Repair - Vessels listed in the Ship Values page with a "+P" after their speed code have unusually good waterline Protection which allows them to avoid or delay severe flooding problems that would otherwise slow and endanger the ship. This status is shown on the ship log as a "+P" next to the "SPEED" header (SPEED+P). Ships with this code can use the S+P repair line, which makes the repair of Speed hits much more likely. Ships without this code must use the regular "Repair S" line on the damage table. As with regular ships, those with Speed+P capability cannot repair SX Hits caused by torpedoes or explosions.

« 4.3 Sinking
Any vessel that has suffered two or more unrepairable speed hits (SX hits) is considered at some risk of sinking. At the end of each turn, roll one twelve-sided die (1D12) for each vessel with the two or more hits, applying the die roll modifier if necessary. If the modified result is equal to or less than the value shown in the Die Roll column for a vessel the corresponding number of SX Hits, that ship has sunk and is removed from the board.

Example: The French cruiser Dupuy de Lome has five SX hits. Because of this, she will sink on any turn that a 1 through 4 is rolled on the dice. If there is an explosion on board (ships with zero movement continue tracking on-board events) which causes more SX hits, the risk of sinking will increase as additional SX hits accumulate.

End of Turn — Once all damage and sinking tests are completed, the turn in complete. If the game is to continue, players now begin a new turn by conducting a new movement phase.
