Integrated performance prediction routines facilitate the evaluation of the hull design quickly in the early design stage. NAPA’s Open GL graphics and lighting, sectioning and curvature plotting tools allow the user to quickly and visually evaluate the fairness of the hull. The unique NAPA hull design methodology allows better control and more flexibility in the hull surface than other modelling systems while still maintaining the exactness needed for final fairing work. NAPA supports several methodologies for hull design, including real 3D surface modelling, transformations, parametric definitions and more. NAPA’s topological approach to hull surface definition facilitates fast and easy design, and increases productivity. The hull surface is usually the starting point for any design and analysis done in NAPA, and forms the basis for the compartment and structural models. NAPA brings the conceptual hull form all the way to the production stage, including final fairing. A true surface model of the hull is created, avoiding old-fashioned techniques based on interpolation.

The NAPA system contains state-of-the-art tools for hull form definition and optimization. It must begin with one of the letters of the mudari: hamzah, nun, ya or ta. 3.2 THE FI L MUDARI (PRESENT TENSE) RULE 5: The fi l mudari (present tense) is every verb that signifies the occurrence of an action in the present or future.
