A marine vessel running controlling apparatus is applicable to a marine vessel which includes a propulsive force generating unit having an engine with an electric throttle as a drive source for generating a propulsive force to propel a hull of the marine vessel. Such a turbine blade consists of a massive blade base and a low-mass blade leaf. The two gates adjacent with each other in a width direction of the bit line are connected to different word lines. The absolute time is then used to compute another position at a subsequent time. A track is sized to receive the rail, wherein the track has a second quantity of ratchet teeth, and wherein the first quantity of ratchet teeth are engagable with the second quantity of ratchet teeth when the rail is positioned at least partially within the track.
