Abstract:
A method for systemizing the creation of original hull designs in such a way as to expedite the design process and the subsequent hull construction process, said method comprising the following steps:(a) produce an initial scaled lines drawing depicting a new hull, including a stem and a stern from said new hull, said initial scaled lines drawing defining basic hull parameters and displaying a plurality of stations distributed along said hull wherein said plurality of stations includes a midships station located substantially midway between said stem and said stern and wherein said basic hull parameters include a sheer line, a bottom line, a half-keel line, and freeboard-defining waterline; (b) create a midships frame drawing on said initial scaled lines wherein said midships frame drawing is associated with said midships station, and wherein said midships frame drawing obeys offset requirements associated with said sheer line and said half-keel line; (c) determine from said midships frame drawing a midships frame drawing waterline offset point and, using said midships frame drawing waterline offset point, complete a design waterline (DWL) around an entire circumference of said hull; (d) extend said midships frame drawing at both ends thereof so as to produce a Single Frame Curve; (e) transfer said Single Frame Curve to a translucent sheet; (f) moving said translucent sheet to a second one of said plurality of stations on said initial scaled lines drawing, and modifying said Single Frame Curve if necessary, locate a second segment on said Single Frame Curve such that said second segment has a shape and length permitting said second segment to outline a second frame complying with said offset requirements of said sheer line and said half-keel line and also complying with an offset requirement established by said design water line; (g) use said Single Frame Curve at each of said plurality of stations to draw a corresponding frame that lies on a segment of said operational Single Frame Curve.
