  2. Length between perpendiculars - Wikipedia

    en.wikipedia.org/wiki/Length_between_perpendiculars

    Graphical representation of the dimensions used to describe a ship. Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member.

  3. Length overall - Wikipedia

    en.wikipedia.org/wiki/Length_overall

    Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth [1] (for example, £2.50 per metre LOA).

  4. Hull (watercraft) - Wikipedia

    en.wikipedia.org/wiki/Hull_(watercraft)

    Length between perpendiculars (LBP or LPP) is the length of the summer load waterline from the stern post to the point where it crosses the stem. (see also p/p) Length overall (LOA) is the extreme length from one end to the other. Moulded depth (D) is the vertical distance measured from the top of the keel to the underside of the upper deck at ...

  5. Ship measurements - Wikipedia

    en.wikipedia.org/wiki/Ship_measurements

    Length between perpendiculars – The distance between where the forward part cuts the waterline and the rudder post of the ship. Length Overall (LOA) – The maximum length of the ship between the ship's extreme points; important for berthing purposes. Length at Waterline (LWL) – The ship's length measured at the waterline.

  6. Marine thruster - Wikipedia

    en.wikipedia.org/wiki/Marine_thruster

    Repairs being performed on the bow thruster of the Bro Elizabeth. Positioning thrusters come in applications, Bow thrusters at the forward end of the vessel, and stern thrusters mounted aft on the boat. Their purpose is to maneuver or position the boat to a greater precision than the propulsion device can accomplish.

  7. Waterline length - Wikipedia

    en.wikipedia.org/wiki/Waterline_length

    A vessel's length at the waterline (abbreviated to L.W.L) [1] is the length of a ship or boat at the level where it sits in the water (the waterline). The LWL will be shorter than the length of the boat overall (length overall or LOA) as most boats have bows and stern protrusions that make the LOA greater than the LWL. As a ship becomes more ...

  8. Ship motions - Wikipedia

    en.wikipedia.org/wiki/Ship_motions

    A pitch motion is an up-or-down movement of the bow and stern of the ship. The longitudinal/X axis, or roll axis, is an imaginary line running horizontally through the length of the ship, through its centre of mass, and parallel to the waterline. A roll motion is a side-to-side or port-starboard tilting motion of the superstructure around this ...

  9. Beam (nautical) - Wikipedia

    en.wikipedia.org/wiki/Beam_(nautical)

    Graphical representation of the dimensions used to describe a ship. Dimension "b" is the beam at waterline.. The beam of a ship is its width at its widest point. The maximum beam (B MAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (B H) only includes permanently fixed parts of the hull, and beam at waterline (B WL) is the maximum width where the ...
