length between perpendiculars

The arrangements are to apply to fishing vessels of more than 15 metres' length between perpendiculars.

The ratio of the tactical diameter divided by the ship's length between perpendiculars gives a dimensionless parameter which can be used to compare ships manoeuvrability.

While some use gross tonnage, capacity, or length between perpendiculars as the criterion, the most commonly accepted standard is length overall (LOA).

Length between perpendiculars, often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP is a term describing the length of a ship.

The naming of this class of ships has some confusion because some sources use the overall length of 522 feet and designate them the 522 class while others use the length between perpendiculars of 502 feet and refer to them as the 502 class.
