Abstract: A marine vessel including a hull extending horizontally from a bow to a stern with a midpoint therebetween. The hull has opposing walls that extend upwardly, where the opposing walls have inner sides that face inwardly toward each other and outer sides that face outwardly. A first of the outer sides defines a first opening therein that is horizontally closer to the midpoint than to the stern and horizontally closer to the midpoint than to the bow. An engine compartment is configured for positioning an engine therein. A first conduit fluidly couples the first opening and the engine compartment for at least one of ventilating and exhausting the engine compartment. The first opening is positioned to prevent water from entering the first conduit.
