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 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.

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 Speed 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 (Heavy versus Heavy, Light versus Light) and establish the percentage difference between the two.
4) Roll all three 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 all three 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.

Long Range: A ship firing into the long range bracket may only use its Heavy Gunnery Rating, and that rating must be compared against the corresponding Heavy Armor Rating of the target ship.
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. The Heavy and Light Gunnery may be fired as two different die rolls at two different targets, or both at one target, or even as a single die roll against one target with each calculated separately off one die roll (to save game time and die rolls).
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 an 8 or less on the two white dice to score hits. If the player rolls a 7 or 8, they will score the two hits. If they roll a 6 or less they score one hit. The only additional thing to remember beyond that is whether the hit and related point(s) was for Gunnery or Speed.

Example: The Japanese battleship Mikasa is conducting long range Heavy Fire at the Russian battleship Borodino. The Mikasa player's fire die roll is 2,5,5. The black die roll of "2" means that the Mikasa did fire this turn because its heavy ROF rating is a 5. 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, which requires a white die total of 9 or less and allows up to two possible hits per result. Because of her die roll, the Mikasa misses the Borodino. Had she rolled a 4,1,3, she still would have fired for the turn, and with a white die total of 4, she would have scored one Speed (S) hit on the Borodino. Had Mikasa rolled a 6,4,5, she could have inflicted two Gunnery hits, but unfortunately her black die roll of "6" would mean that she failed to fire. As a result, no hits would be scored even though the white dice gave a good result. The black die roll must indicate that gunfire occurred in order for the white die roll totals to count toward damage.

Example: Two battleships with a Heavy Gunnery value of 20 heavy points each, fires on a target with 10 heavy armor points. The attacker will use the 300 line (meaning 300%) because of the 40 points firing onto the target, but will roll the fire dice only once (even though there are two ships firing) with only a single hit line applying. If the two example battleships roll a 10 on the white gunnery dice, they will score three Speed Hits (not six hits). Had the two ships rolled independently, they would have rolled once each on the 200 line. Had the ships rolled a 6 or less, they would have scored on the Blast Damage table due to the minus two (-2) modifier for joint fire, thereby scoring fewer Speed Hits but starting a fire. At closer ranges, the Blast Damage effects tend to become more dangerous with the joint fire modifier.

« 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.

Destroyer Damage - Because a destroyer's main weapon is its torpedo tubes, all Heavy G Hits inflicted on destroyers (and torpedo boats) are considered S Hits instead, and all Light G Hits on them are considered T Hits instead. This applies in addition to any boat gun damage, which is handled separately as noted above.

« 4.2 Damage Repair
Each turn after active fires have been checked (See Turn Sequence), players may attempt to repair Gunnery, Speed and Direction 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 two six sided dice (2D6) 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 and Speed Hit, the player could be allowed to roll three 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.

« 4.3 Sinking
Any vessel whose speed boxes are all crossed-out by Speed Hits is considered in danger of sinking. At the end of each turn, roll two six sided dice (2D6) for each vessel with zero speed, 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 of corresponding size, that ship has sunk and is removed from the board.

Example: The French cruiser Dupuy de Lome has nine Speed Hits. This means that all of her speed boxes are marked off, and there is an extra "S" written in the margin next to her speed boxes (or written in the bottom of the Blast Hits box next to it). Because her size is a 7, she will sink on any turn that a 2 through 7 is rolled on the dice. If there is an explosion on board (ships with zero movement continue tracking on-board events) which causes more S Hits, the sink roll range will increase as the extra speed hits pile up.

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