1. • Below the profile is the half-breadth or waterlines plan, Fig. A26,
which shows the intersection of the hull form with planes parallel to
the base plane, Fig. A27.
• All such parallel planes are called water planes (see Fig. A16).
• It is convenient to space most water planes equally by a rational
number of meters (or an integer of feet), Fig. A15, but a closer
spacing is often used near the Molded Base Line (MBL) where the
shape of hull form changes rapidly (see Fig. A15 and Fig. A12).
• In the body plan and sheer plan, the waterplanes are represented
by straight lines called waterlines (see Fig. A16 and Fig. A12).
• DWL represents the design waterline, near which the fully loaded
ship is intended to float (see Fig. A1 & Fig. A2).
