Richelieu-class battleship and more broadly the proximity between the two main artillery magazines (one for each turret), was the greatest risk: one hit could potentially neutralize the entire main battery, or even cause the ship's loss from an ammunition explosion. On "Dunkerque", to avoid this risk the forward turrets had been positioned apart from each other, further apart than on the "Nelson"-class battleships. The French also studied three-turret designs, such as one quadruple and two double, two triple and one double, or three triple. In every case, three turrets would have increased weight vs two quadruple turrets, reduced propulsion to and speed
Double (volleyball) and indicates outstanding all-around individual performance. Quadruple-double is defined as an individual performance in which a player accumulates a double digit number total in four of the five major statistical categories--aces, kills, blocks, digs, and assists--during the course of one match. Because of specialization by position (setters, liberos, middle blockers, outside hitters, opposite hitters, defensive specialists, etc.), quadruple doubles are seldom seen at collegiate or professional levels. Quintuple-double is defined as an individual performance in which a player accumulates a double digit number total in all five statistical categories (aces, kills, blocks, digs, and assists) in a single match.
