“…Wang and Lutsey [3], as well as Molland et al [4], have described several methods to increase the efficiency of energy use on ships. These methods include weather routing [5], [6], speed reduction [7], [6], propeller [8], [9], and hull optimization [10], [11], bow modification [12], [13], [14], hull cleaning management or preventing biofouling [15], [16], [17], [18], [19], [20], trimming strategy [21], adding devices [22], [23], [24], [25], [26], using more advanced antifouling [27], [28], [29], and analyzing the coating roughness [30], [31], [32], [33], [34], etc.…”

The selection of a hull design with minimal drag is an important effort to reduce emission levels on ships. Two different hull shapes, U and V hulls, have unique properties that affect their drag production, which has been studied extensively in the past. This study aims to re-examine the differences between the two hull types by conducting a simple analysis of drag prediction results using empirical and numerical slender body methods. Both hull models in this study have the same size and volume. The results indicate that the U hull has a higher frictional resistance ( ) than the V hull due to its wider wetted surface area ( ). Additionally, the viscous pressure resistance ( ) and form factor coefficient ( ) of the U hull are also higher than those of the V hull. However, for Froude numbers (Fr) above 0.245, the U hull has lower wave resistance ( ) than the V hull, whereas for Fr below 0.245, the U hull has higher . Overall, the U hull produces a higher total resistance ( ) than the V hull at low speeds, but a lower at high speeds. Therefore, the choice of hull shape for minimizing a ship's resistance is influenced by the desired speed of service. If Fr is low, below 0.24, a V-shaped hull is more suitable. However, if Fr is higher than 0.24, a U-shaped hull is more appropriate.

“…There is always a tendency to enhance hull characteristics in order to minimize resistance during ship operation. Several studies have been conducted in order to reduce the resistance on the ship's hull during operation by altering hull form [19,20], demi-hull configuration [21], and hull-propulsion [22]. High-speed crafts operating in planning modes face a variety of stability-related risks, such as decreased transverse stability with increasing speed [23].…”

A typical ship must operate in extreme conditions in the open coastal zone. Due to the severe operation at sea, comparative research on the design of the hull shape for optimization purposes will be important, specifically in the resistance and movement aspect. In this regard, an investigation was carried out by varying the total of four V-shaped monohull models from the high-built design as the main subject to compare several hull shape designs at the same displacement to obtain better performance at stability, resistance, and seakeeping criteria. Savitsky formula is used to calculate the hull resistance, and the stability analysis is calculated analytically by comparing the relationship between righting arm and heel angle. Moreover, ship motion is investigated by examining heave and roll response amplitude operator (RAO) and Motion Sickness Incident (MSI) index due to wave height 0.1 m. The most significant feature in this study is resistance since, with limited power, a minimum resistance value is necessary for best outcomes. It can be found that Model I is a superior model in terms of resistance, stability, and seakeeping performance to other models. However, Model III is not recommended since it has high resistance and bad stability and motion performance. From these results, it can be summarized that Model I is selected as the best hull form model.
