Definitions

  • FIGURES 1a and 11 represent diagrammatical longitudinal vertical midsections of the fore end of a ship incorporating the simplest embodiment of a bulbous bow;
  • the most forward part or nose of the bulb can conveniently be located within 30% to 40% displacement waterlines, which, in practice, is more or less equivalent to saying that the height of the nose of the bulb over the keel line is about 30% to 40% of the maximum draft of the ship. This provides that the nose of the bulb is always submerged (except when the ship is pitching violently) and that a substantial proportion of the bulb is above the BWL.
