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) Active Fires — All ships with fires burning on board 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 blasts or 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 zero speed 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° during any one turn. If she uses her fourth speed box (3-inches) she would be able to turn 90° during any one movement. 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 couldn't turn at all. If she turns once at the start of her movement (before having moved forward at all), she must move at least 3½-inches before making a second turn - the 3¾-inches being the distance listed in her fifth speed box.

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 or light) 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 all three firing dice and establish: a) Whether the ROF die result let the ship fire and; b) Whether the Gunnery dice resulted in a G or S hit.
5) Record 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 Hits box in the ship's log and/or immediately resolve the damage in the Damage table.

ROF Die Roll Modifiers
1st Fire - Subtract one (-1) from the die roll if this is the first time in the game that the ship is firing.
Failed last ROF roll - Subtract one (-1) from the die roll if the ship's last ROF roll failed to let the ship fire. Applies both to attempts made this turn or on the previous turn, non-cumulative (maximum modifier is -1).

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 two hits. Any value less than 9 rolled on the two dice will score the two hits. The only additional thing to establish beyond that point is whether the hit (and related points) was for Gunnery or Speed. If the gun/armor differential is less than 150%, just one hit point is scored per die roll.

Example #1: 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. This means that the Mikasa misses the Borodino. Had the Mikasa 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 two Speed (S) hits on the Borodino. Had Mikasa rolled a 6,2,1, she would have rolled a white dice total that might have allowed a Gunnery hit, but unfortunately her black die roll of "6" would mean that she failed to fire. As a result, no "S" hit would be scored even though the white dice gave that result. The black die roll must indicate that gunfire occurred in order for the white die roll totals to count toward damage. Otherwise they count for nothing.

Torpedo Die Roll Modifiers
Converging Targets - Subtract one (-1) from the die roll if the courses of the firing ship and the target ship are converging (moving toward each other). Does not apply to ships on parallel or diverging courses.
DD Launching - Subtract one (-1) from the die roll if the torpedoes are being launched from a destroyer or torpedo boat.

« 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 may 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 adding a code to the blast damage box or simply crossing something out is the best course.

« 4.1 Damage Types
Several of the Quickfire combat chart tables contain abbreviations of damage which may be inflicted on participating vessels. Each of these damage codes triggers 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 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 loss each turn. For example, if a ship has suffered three Gunnery hits, up to three repair die roll attempts may be made that repair phase. 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)" next to 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 unrepairable Speed hits caused by torpedoes or mines.

« 4.3 Sinking
Any vessel whose speed is reduced to zero is considered in danger of sinking. At the end of each turn, roll two six sided dice (2D6) for each vessels with zero speed, applying all pertinent modifiers to the die roll. If the modified result is equal to or less than the value shown in the Die Roll column for a vessel of corresponding size, the vessel in question has sunk and is removed from play.

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). She also has one fire burning on board. Because her size is a 7, she will sink on any turn that a 2 through 8 is rolled on the dice. If the fire goes out, the sink roll is reduced to a 2 through 7. If there is an explosion on board instead (ships with zero movement continue tracking on-board events) which causes two more S hits, the sink roll will increase to a 2 through 10.

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.
