“…The consideration is valid at least once the comfort analysis employs strip-theory calculations. Furthermore, the ranking includes only comfort criteria, not the only design attribute for a large yacht, especially once green [41,42] and digital [43] transitions are becoming extremely relevant to the ship design process.…”

The importance of comfort during transfer and stationing becomes a key performance parameter for large yacht design, on the same level as propulsive issues. Such a matter extends questions in terms of form and service demand to the motion behaviour of the unit in waves. Relevant studies refer to outdated hull forms not specific to modern large yachts. In this study, five hull forms with different bow concepts represent the most common design solutions for yachts at constant draught and displacement. The preliminary ranking on the effect of alternative bows on comfort requires the definition of internationally accepted comfort standards. Here, the AWI 22834 guidelines for large yachts provide the service and environmental conditions and criteria for the comfort analysis, being the only reference specific to yachts. The calculations employ a strip-theory-based numerical model to provide results of easy understanding for designers during the early design stage. The obtained ranking among the design solutions on a reference large yacht favours the option nested with a bulb, contradicting the expectations in favour of a vertical bow concept. The discussion and conclusions provide a way forward for additional analyses and investigations aimed at proposing suitable multicriterial design guidelines for large yachts. However, the results also show the unsuitability of AWI environmental and encounter conditions for hull form ranking.

“…The KISS project is an example of a successful electric small craft with a performance and mission profile comparable to competitors using conventional propulsion. A concurrent design that considers the hull form, engine, propulsion system, and onboard energy storage has achieved such a goal [17]. The study investigated the factors that influence the viability of nautical tourism in a number of Mediterranean countries to identify the major barriers to greater use of renewable energy sources.…”

This research investigates the application of photovoltaic (PV) systems on ship retrofits with the aim of reducing the emission of harmful gases. By using renewable energy resources, this research presents the potential for reducing greenhouse gas (GHG) emissions and improving energy efficiency in maritime operations, specifically within the Split coastal area. Overcoming the space restrictions on ships, an innovative design is presented to maximize the installation area for solar power. The research is conducted for several cases based on the IHOGA simulator, for all ship phases, and it aims to minimize fuel consumption by the diesel generators, thus emphasizing the use of renewable energy resources. A model with two operational modes is designed: Mode 1 allows surplus power to charge batteries or supply the port network, while Mode 2 covers power deficits from alternative sources. The implementation of renewables results in carbon dioxide (CO2) and nitrogen oxide (NOX) emission reductions. Furthermore, during the ship hotelling phase, the load is supplied entirely by batteries, resulting in zero emissions at the port.

“…Such factors have been widely discussed individually on different kinds of ships (Tonelli et al, 2015), but an appropriate joint investigation of small hulls like motor yachts is missing in the open literature. The only guidelines available in the recent literature concern solely the vertical motions in waves (Ivanova & Gyurov, 2022, Begovic et al 2023a, Begovic et al 2020 or dedicated studies on the hybrid-electric propulsion (Geertsma et al, 2017, Bucci et al 2020, Coppola et al 2022, Begovic et al 2022 or dynamic positioning of such units (Mauro et al 2021b). A comprehensive analysis of the effect of different hull forms on the overall hydrodynamic performances of a motor yacht is not yet available, also considering that the relations between hull form parameters and hydrodynamic performance may lead to counteracting solutions while considering, as an example, propulsion or seakeeping characteristics.…”

The design process of motor yachts mainly relies on the experience of designers, who have confidence in the knowledge acquired from designing units with similar hull-form characteristics. However, once a new concept needs to be developed, the acquired experience on a standard platform is no longer sufficient to achieve in a short time a successful design. The design of a motor yacht implies considering multiple aspects of ship hydrodynamics: resistance, propulsion, seakeeping, and manoeuvring. Such factors have been widely discussed individually on different kinds of ships, but an appropriate joint investigation of hulls like motor yachts is missing in the open literature. Therefore, the present paper intends to cover this gap, providing guidelines for the design of motor yachts in a length range between 20 and 40 meters. As a preliminary study, a series of 15 yacht hulls has been developed, starting from a reference hull form. Seakeeping, manoeuvring, and propulsive performances have been evaluated at a reference environmental condition and speeds according to the ISO 22834:2022 guidelines. Such calculations allow for developing response surfaces of the hydrodynamic properties for the series of yachts as a function of the hull's main dimensions. As a final result, the obtained responses allow for identifying the best compromise solutions for the main dimension selection of a new motor yacht in the length range of 20-40 meters.
