“…An early attempt for building a ship parametric model is due to Lackenby [12] in which hull variants are obtained by modifying the prismatic coefficient, the center of buoyancy and the extent and position of parallel mid-body of a parent hull. This method has been subsequently generalized towards improving the geometric coverage of the parametric model through the use of B-spline techniques; see, e.g., Harries and Nowacki [13], Kim [14], Abt and Harries [15], Harries [16] and Ping [17]. In previous works of ours [18,19], a Ship Parametric Model (SPM) has been developed, with the aid of CATIA [20] modeling environment, resulting in a multi-patch NURBS representation of a ship hull.…”

“…The changes of these variations were limited to ± 10% from the initial parameter. The area changes for every station of each model was obtained from (Zhang et al, 2008). Figure 5 shows the body plans derived from each of the eight generated models.…”

Catamaran resistance is very complex compared to monohull resistance, so it is particularly worthy of research. The below-water-level hull form influences the fluid flow characteristics around the ship, which either increases or decreases the total resistance. This study focuses on developing a new hull form by using the Lackenby Method to modify an existing hull form in such a way that reduces the total resistance. The total resistance was calculated using computational fluid dynamics, since the Navier-Stokes equation is built into the Tdyn software. The research results show that hull form changes can in fact decrease or increase the ship's total resistance. The best new hull form was chosen for its value of least total resistance.

“…In another study, Pérez-Arribas et al [15] developed a method for automatically creating hull forms by utilizing a fairing algorithm for NURBS surfaces, and then used these surfaces to create the hull form. Zhang et al [16] used a parametric design approach for rapid creation of ship hulls in order to optimize the hull's hydrodynamics. A geometric parametric technique to produce complex planing tunnel vessels was proposed by Ghassabzadeh and Ghassemi [17].…”

A novel design framework for generation and parametric modification of yacht hull surfaces

This paper proposes a new design framework for the parametric design and shape modification of a yacht hull. In this framework, the hull is divided into three regions (entrance, middle and run) and each region is represented separately. In this way, a designer has better design flexibility so that higher design variations of the hull can be achieved. Each region consists of keel line(s), deck line, chine line(s) and station lines that are represented using Bezier curves and these lines are called feature curves. A 3D surface model of a yacht hull is obtained by generating Coons patches using feature curves. Shape operators are also introduced and implemented for the modification of the given hull shape while considering some quality criteria such as hull fairness. Experiments in this study show that a variety of hull shapes can be generated using the proposed design framework with the application of the shape operators.
