Engine Boost Data
As the name implies, this consumable enhances a ship's engine performance. It is found on all destroyers, but it can be swapped out for other consumables such as Defensive AA Fire 
on some late-hull versions of American destroyers and high-tier Russian destroyers; it is also available to French cruisers at Tier VI and up.
When activated, a boost that grants +8% means that a ship's engine will operate at 108%; or, in other words, it will provide an 8% increase in top speed. This means a ship with 35 knot top speed will reach 37.8 knots. It should be used when being fired upon, as it has a chance of fouling up an enemy's aim (by a small margin). If captains are rushing to attack/defend an area, this consumable should be used as well. Note that Engine Boost will not work if a ship's engine module is disabled (even if the commander has the Last Stand skill). A small cosmetic effect of thicker engine smoke will also appear during the duration of the consumable, however Engine Boost has no impact on a ship's concealment value.
