Figure 3 shows a drawing of typical developed plates of a planing hull.The plate between the keel and
chine line is developed by the Apex method and the other two plates are generated by a Bezier surface
method. (Yoon etc., 2000)

adjustable system (side view) system (transverse view)
An adjustable mould system is constructed on a precision bed as shown in the above figure. The
frames of the mould are used as a reference frame when constructing the ship with composite
materials. The procedures for construction of FRP ship on the adjustable mould are shown
schematically in Figures 4 to 6. On the surface of the flat bed, vertical posts are installed firmly.
