Dissertations / Theses on the topic 'Yacht Design'

This thesis consists of two integrated parts. The main attempt is to design and test a new hull which will reduce the total water resistance and need for engine power, but maintains the stability of a conventional hull. To see if the hull is sufficient enough for a general luxury yacht, there will also be a need for an arrangement design process for the calculation of the needed volume and equipment. Based on external conditions the main parameters for the yacht was set. This resulted in a 30 meter long yacht, with a draught of 1.75 meters and a beam length of 7 meters. The yacht has a fuel capacity of 18 tons and a fresh water capacity of 4000 liters. Regarding accommodation and facilities it has 5 bed rooms, 5 bath rooms, kitchen, restaurant and a room for a small boat. The yacht is equipped with watertight bulkheads to prevent flooding of the complete ship, and floating devices to prevent sinking if the ship should be completely flooded. The yacht will in total have a lightweight of 191 tons and a deadweight at departure of 26 tons. The idea for the new hull is to have a more slender hull than a conventional hull, but maintain the volume in the midship under and over the water surface. This will, in theory, give reduced water resistance because of the reduced waterline beam length. However, when inclining the increase in waterline area will maintain some of the stability. To be able to compare the results it was also modeled a conventional hull for this thesis. This comparison hull has the same main parameters as the new hull, but designed with a conventional midship with long flat sides. The two different hulls were given four loading conditions. The first loading condition had 100 % fuel, fresh water and food supply. The second one had 10 %, and the third one had 50 %. The last loading condition had 100 % fuel, fresh water and food supply and no use of the water ballast tanks. The intact stability was tested for each loading condition and checked up against the IMO criteria for passenger and cargo vessels of all sizes. The calculations showed that the general stability was weakened with 30 percent for the new type of hull, but the increased stability was noticed at 5-10° heeling angle because of the larger waterline area. The new hull with an initial loading condition consisting of 100 % fuel, fresh water and food supply was then tested for three given damage scenarios. In scenario 1 the water entry started on the port side in the fore part of the ship, simulating a crash while coming along the quay. Scenario 2 simulated a front crash, resulting in flooding of the two front water ballast tanks and the chain room. The last scenario simulated a run aground of the ocean floor, resulting in flooding of three water ballast tanks and the fresh water tank. Damage scenario 1 resulted in a heel angle of 21° and the water level reaching 7 centimeters above the hull height. As a consequence of this there must be installed one or two more water tight walls, bulkheads, in the two corridors at this deck. The resistance of the two hulls was predicted with the Holtrop-84 resistance prediction method. Holtrop has implemented statistical results from several model tests in a formula which calculates the ship resistance based on some of the main parameters of the hull form. Based on the results from this test the new hull required 24 % less engine power than the conventional hull. This can save fuel for over 72 000 US$ per year. The new hull design has both its advantages and disadvantages, but much research remains before it can be either refused or accepted as a new way to design ship hulls. The stability and resistance can in general not be compared, but the calculations show a larger reduction of the stability than for the resistance, which implies that both changes and more testing must be executed before the new hull can be introduced to the yacht market.

Theme of this diploma thesis is design of residental yacht, focused on applying of modern technologies with aim to make the work flow more efective. I would like to achieve better results in question of fuel saving and ecology, by using hybrid engine systém and solar power. My next aim was interlacing of construction and ergonomic parameters in the way to achieve comfort and save enviroment for the travelers.

Electrical vehicles are getting more popular as the technology around batteries and electrical motors are catching up to the more common combustion engines. Electrical boats are no exception but there are still a lot of boats using old combustion engines that have a big impact on the environment. This study aims to deepen the understanding of the integration of electrical motors into boats by proposing a design of a system using a bidirectional synchronous buckboost converter. This converter is designed to handle the power transfer in a dual battery application, namely consisting of a 12 V battery and a 48 V battery. The converter includes proposed components, a PCB design, as well as the software that is required for the control of the power transfer. The results show that the converter design meets specification and, when using a test-bench, the software is capable of controlling the converter to achieve constant current and constant voltage in both directions.

Wave drag significantly affects ship powering and speed prediction calculations, and the performance of sailing yachts. Linear Neumann-Kelvin ship wave theory is taken as a starting point for the development of a computational approach for predicting water flow about yacht hulls. Previous work by Baar and Price, Newman, and Doctors and Beck for the calculation of the Kelvin source and its derivatives and their use with panel methods is repeated, refined and extended. Consistent and accurate results are obtained for numerical tests and Farell's submerged spheroid test cases. Baar and Price's results for the Wigley hullform (which compare well with experiments) were not able to be duplicated in the present study, despite significant tests of both local and integrated solution values. The tests did indicate that the current implementation was behaving correctly, and gave wave resistance results equivalent to those from Doctors and Beck's study, to a level of agreement which contrasted sharply with the wide scatter in Chen and Noblesse's survey. These results remove to some extent numerical inaccuracies as a postulated source of the theory's difficulties, leaving the conclusion that Neuman-Kelvin theory, as it is currently understood, does not give satisfactory wave resistance results for realistic ship hullforms. These and further results lead to, and reinforce, the suggestion that the problem lies with the waterline integral term; a new treatment of this term may substantially increase the applicability of Neumann-Kelvin theory. The extensions required for modelling sailing yachts are considered. Investigation of three yacht design problems show that the developed model can predict, and partly explain, previously observed free surface effects. These 'relative' effects may be adequately predicted even though the absolute results appear less reliable. For the simplified parabolic yacht hullform tested, the sideforce is relatively constant over the speed range generally relevant to upwind sailing, and well modelled by the (zero Froude number) cosine squared (heel angle) relationship. The effects of a bulb, and heel (for the Wigley hullform), on wave resistance are shown. Suggestions for further work, calculation details, and tables of wave resistance and Kelvin source (and gradient) values are given.

Les performances et le comportement d’un voilier ne peuvent pas être prédits par une seule étude hydrodynamique comme pour les navires à moteur. En effet, le voilier tire sa propulsion de l’écoulement de l’air dans ses voiles ; son comportement est donc régi par l’équilibre des effets aérodynamiques et hydrodynamiques. Une prise en compte couplée de ces deux effets est indispensable pour une bonne compréhension du fonctionnement global du voilier. Une simulation complète incluant les effets hydrodynamiques sur les œuvres vives et aérodynamiques sur les œuvres mortes et les voiles est encore hors de portée des modélisations actuelles. Le recours au VPP (programme de prédiction de vitesse) reste indispensable. Ce type de logiciel tire partie d’un ensemble de résultats hydrodynamiques et aérodynamiques (issus de la simulation, d’expériences ou de lois empiriques) pour prévoir le point d’équilibre du voilier et ainsi en déduire son attitude et sa vitesse dans des conditions de vent données. Les lois empiriques utilisées aujourd’hui pour caractériser le comportement hydrodynamique des carènes de voilier sont issues de séries systématiques dont les caractéristiques sont très éloignées de celles des voiliers modernes, induisant un décalage important entre les performances prédites et les performances réelles. Après un résumé détaillé des différentes méthodes existantes pour approximer le comportement hydrodynamique des carènes de voilier, ce mémoire présente une méthodologie de génération de nouvelles formulations. Cette méthode repose sur de nouveaux résultats de simulation générés par une boucle de calcul automatique. Le fonctionnement de la boucle de calcul et de ses différents composants est d’abord décrit. Depuis la génération des formes de carènes jusqu’à leur évaluation par un logiciel de simulation numérique et le stockage des résultats dans la base de donnée. La méthode de caractérisation géométrique des carènes par calcul hydrostatique est particulièrement développée, ainsi que les outils statistiques utilisés pour construire les formulations à partir de la base de données. Un accent est mis sur le processus de sélection des variables les plus pertinentes pour expliquer les phénomènes physiques mis en jeu. Deux séries systématiques sont décrites et analysées, permettant la mise en application des outils décrits précédemment. Les variables sensibles mis en évidence sont présentées, ainsi que les formules de régression permettant l’approximation des différents efforts et positionnements dynamique des carènes en fonction de leur forme et des conditions extérieures. Ces formulations sont finalement évaluées par une étude de cas sur un monocoque de course au large de type Volvo 70, permettant d’évaluer la méthodologie présentée
Unlike most of engine powered ships, the performance of a sailing yacht cannot be predicted trough a sole hydrodynamic study. In fact, sailing yachts behaviour relies on the equilibrium between aerodynamic and hydrodynamic effects. A coupled modelling of those two elements is therefore required to characterize the yacht behaviour. A fully coupled simulation including the aerodynamic of the sails and topsides as well as the hydrodynamic of the wetted part of the hull is out of reach of current numerical tools. Velocity prediction programs remain essential. This type of program computes the equilibrium between aero and hydrodynamic forces to predict the yacht’s attitude and speed under given wind conditions. These forces are approximated using formulations, based on numerous results coming form experiments, simulations or empirical laws. The hydrodynamic models available nowadays for the design phase of the yacht are based on systematic series. Today’s hull shapes are far from the shapes used to build these series, leading to significant discrepancies between the predicted and the real performance of the yachts. After a detailed description of the existing formulations on the hydrodynamic behaviour of sailing yachts, this report presents a methodology to build new formulations. This method is based on new simulations results generated by an automated computational loop. The different tools used in the loop are described, from the generation of the hull shapes to their hydrodynamic evaluation using numerical simulation and the storage of the results in the database. A focus is made on the geometrical characterization of the hulls using hydrostatic computations. The methodology and the statistical tools used to build the formulations from the database are then described, with an emphasis on the variable selection process. Two systematic series are presented and analysed. The variables which have been selected as the most relevant to describe the physics involved are presented along with the formulations describing the forces and running attitudes of the hulls, depending on their shape and the external conditions. A benchmark of the presented formulations is finally provided. The case study of on an offshore racing monohull complying with the Volvo 70 rule is presented to evaluate the proposed methodology

The topic of this master‘s thesis is design and analysis of a sailing boat in accordance with ergonomic and technological requirements. The goal is to create a sailing boat, which will be modern, visually interesting and which and which will take future development of both design and technology into account.

Windy Scandinavia is the manufacturer of the luxury yacht Windy 52 Xanthos. There is a storage application in the aft sofa on the boat that doesn’t live up to the standard and functionality level that Windy represents. This report describes the mechanical design process of this storage application, which currently has bad functionality and is expensive for Windy in production.

The aim of the project was to develop the existing storage application to a low cost application. Simple and effective for Windy to produce and assemble, with the directives of access to the front or from above to the sofa.

A feasibility study of the existing application was made to get a picture of disadvantages and advantages to keep for further concepts.

The concept development included three steps; each step implied further development in level of detail. Starting with a range of concepts covering all different possibilities of access to the storage space, and ending up with a couple of concepts developed in detail with costs and knowledge of productions methods.

The result became a standard application; a hatch with gas dampers. The reasons why this became the result was because of the low cost, simplicity and functionality. Small modifications of existing moulds and no new components or production methods needed.

Conclusion of the result is that it fulfils the requirement specification and thereby is a proper result. The conceptual design phase generated many different concepts, from these concepts a result satisfying the requirements emerged.

This thesis presents the design of an inertial measurement data acquisition system intended for use in sailboats. The variables of interest are 3-axis acceleration, 3-axis rotation, GPS position/velocity, magnetic compass bearing and wind speed/direction. The design focus is on low-cost micro-electromechanical systems (MEMS) based technology and demonstrating the validity of these technologies in a scientific application. A prototype is constructed and submitted to a series of tests to demonstrate functionality and soundness of the design. These tests range from bench tests to full scale application. Contributions of this thesis include the novel application of inertial measurement unit (IMU) technology to a sailboat racing application, the integration of all instrumentation, creative ruggedised packaging and emphasising the use of low-cost commercial off-the-shelf (COTS) technology.

Proposed in this thesis is a methodology to enable yacht designers to develop innovative structural concepts, even when the loads experienced by the yacht are highly uncertain, and has been implemented in sufficient detail to confirm the feasibility of this new approach. The new approach is required because today??s yachts are generally lighter, getting larger and going faster. The question arises as to how far the design envelope can be pushed with the highly uncertain loads experienced by the structure? What are the effects of this uncertainty and what trade-offs in the structural design will best meet the overall design objectives? The new approach provides yacht designers with a means of developing innovative structural solutions that accommodate high levels of uncertainty, but still focus on best meeting design objectives constrained by trade-offs in weight, safety and cost. The designer??s preferences have a large, and not always intuitive, influence on the necessary design trade-offs. This in turn invites research into ways to formally integrate decision algorithms into knowledge-based design systems. A lean and robust design system has been achieved by developing a set of tools which are blanketed by a fuzzy decision algorithm. The underlying tool set includes costing, material optimisation and safety analysis. Central to this is the innovative way in which the system allows non-discrete variables to be utilized along with new subjective measures of structural reliability based on load path algorithms and topological (shape) optimisation. The originality in this work is the development of a knowledge-based framework and methodology that uses a fuzzy decision making tool to navigate through a design space and address trade-offs between high level objectives when faced with limited design detail and uncertainty. In so doing, this work introduces the use of topological optimisation and load path theory to the structural design of yachts as a means of overcoming the historical focus of knowledge-based systems and to ensure that innovative solutions can still evolve. A sensitivity analysis is also presented which can quantify a design??s robustness in a system that focuses on a global approach to the measurement of objectives such as cost, weight and safety. Results from the application of this system show new and innovative structural solutions evolving that take into account the designers preferences regarding cost, weight and safety while accommodating uncertain parameters such as the loading experienced by the hull.

The initial objective of this thesis aimed at comparing the performance characteristics of two yachts belonging to King Charles II of England during the latter years of the 17th century. This goal, which called for accurate modelling of the shape of each yacht, was extended to investigate the design processes used by Dutch and English shipwrights of the period. It was soon decided that, instead of focusing on the performance of each ship or, more precisely, of their theoretical ‒therefore questionable‒ reconstruction, this research would focus on the design knowledge of the early modern period used to design the different yachts and contemporary ships. This was necessary, firstly, as a means of helping with the theoretical reconstruction which was one of the initial aims of the research. But, most importantly, it was necessary to produce a picture of the knowledge-space in which ships of this period were designed and built. Consequently, this research offers an overview of the current narrative that describes ship design knowledge of the early modern period and criticises some aspects of it. Moreover, as the current understanding of such knowledge is included within a longer narrative that describes ship design knowledge of shipwrights from the earliest known examples of ships to the present, this research also looks into the manner in which ship design knowledge is understood within such a long narrative. This research provides arguments to show that ship design knowledge could be re-defined. It provides a more nuanced description of the design knowledge of traditional shipwrights and includes the knowledge of early modern shipwrights within this re-modelled narrative.

In the past, small yachts made in Taiwan occupied an important position in the world. Recently, the shipbuilding industry in Asia has grown fast and domestic economic factors have made the competitiveness of the market in Taiwan decline gradually. For building custom-made luxurious yachts, because the shipbuilding industry in Taiwan owns the exquisite woodworking and the ability of yacht designs, they bring business opportunities again. Design processes of yachts are complicated and need to consider a lot of factors. Therefore, this study employs the analysis method of value engineering (VE) and applies five-step job plan that contains the information gating phase, the creative phase, the evaluation phase, the presentation phase and the implementation phase. This study builds the procedure which uses the concept of VE to assist the yacht design process and propose fuzzy comprehensive assessment to evaluate the plans. The theory of evaluation adopts the fuzzy comprehensive assessment that can estimate quantifiable and qualitative indices and increase the credibility of the best substitute plan. In addition to consider the price, we also take into account requirements of customers, feelings and variables of the beauty as the development of design. This study shows that the combination of real yacht design plans and VE, processes of yacht designs. Moreover, we obtain the excellent sort of each case as the reference of yacht designs. From the analyses of cases, in addition to the price, different appearances of ship models can also affect final sorting. On the other hand, the operation rule of fuzzy comprehensive assessment makes different sorting results. The matrix operation is suitable for evaluating the yacht design plans. Therefore, VE can be used to investigate preliminary evaluation of the yacht designs and can help yacht designers fit in with the shipowner’s demand and have high acceptable value.

With the rising of economy and increasing of national income, the yacht recreation has become one of the options of entertainment in Taiwan. However, there are many risks along with the yacht activities which causing the loss of life and damage of properties. Hence, a yacht insurance with fully covered is a good way to provide safety protection on yacht recreation. Mitigating or removing the uncertainty of loss by insurance is easier and much efficient than others’. It’s not only reducing the cost of society, but making consumers feel relieved while taking relative activities. Because of the yacht insurance consists of several insurance policies at present, causing the inconvenience when consumers requesting insurance and the leakage or insufficiency of coverage which must be integrated all of the coverage into one and design a new yacht insurance policy. Therefore, this study refer to several yacht insurance policies in many countries as samples in accordance with the need of development on ours yacht insurance in the future; designing a comprehensive policy of yacht insurance as a referral on new product design in general insurance industry in Taiwan. The study includes the theories of designing insurance product. In addition, there are also including the structure and risk exposure of yacht to be the facts of rate estimation. Therefore, this study generalize the literature and article about yacht insurance, yacht insurance policies, safety information and others’ relative information to illustrate the main framework of comprehensive policy of yacht insurance in the version of our country. The study considers our local customs and regulation, comparing with the yacht insurance in America, England and Japan, and combining the advantages around them which fit our realistic circumstance for designing comprehensive policy of yacht insurance, besides making a description of management. The study ends in conclusions and suggestions to put a new view on general insurance industry and government for developing yacht recreation and yacht insurance in the future.

In order to increase riding comfort in vehicles such as cars, motorcycle and bicycles, the suspension system is designed to improve. Many people are committed to improve the vehicle stability and comfort, but that of the ship at sea is rarely mentioned. While paying attention to the ride comfort of the vehicle, the stability of the ship on the sea should not be ignored. In addition to the hull structure, if the suspension of the seat on the ship could achieve more comfortable? Therefore, the component modeling of this study was performed by computer-aided simulation software ADAMS/View. Through the software analysis ability, we could realize the difference between the performance and the parameter adjustment of the purpose for the suspension mechanism of the yacht and the seat. The results show that the vibration of the suspended suspension parameters is going to be increased with the increase of the damping ratio. According to the data, it is known that the energy for absorbing the Z-direction vibration is better at the damping ratio of 0.01.When the suspension seat is in the over-damped state, its angular velocity is relatively lower than that in the under-damped state, but it is still higher than that of the unsuspended seat.

The purpose of this study was to discuss the current requirements for interior design and decoration professional manpower in the yacht-building industry, in order to analyze the gap between industry practice and personnel cultivated through educational training. By means of in-depth interviews and the distribution of questionnaires to yacht company professional technicians and specialists who participate in industry-university collaborations, this study attempted to understand the gap between educational training course management and the actual requirements of the workplace. This study found that Taiwan has the advantage of not only skilled handicraft, but also high industry adaptability, with high levels of cooperation that make the local industry a significant presence within the global yacht market. However, in terms of interior design and decoration, Taiwan has never been able to discard the role of OEM. Poor working environments discourage young people from joining the industry, causing significant shortages in manpower at present. Educational institutions are making considerable efforts at training new personnel, and it is suggested that institutions should place emphasis on the diversification of core coursework, the gaining of professional experience, as well as detailed planning for and implementation of the length, time, content and appraisal system of internship training. It is hoped that a professional yacht-building appraisal system be established to enable professional workers’ ease and adaptability in the design process, to increase individual competitiveness and propel the economic benefits of yacht production.

Indonesia has the opportunity to increase a sailing and tourism pleasure activity using yachts. But the yacht industry in Indonesia has not developed properly. Recently Indonesian government is trying to increase the potential of yacht industry to support the coastal tourisms. To support the government's program, a tourism pleasure yachts is needed. The first step of this research is to collect data and analyze market demands of yachts in Indonesia. From the data analysis, we got that the contributions of the sailing yacht for giving the good impact in Economic sector is low. While the facilities as a yachting center is quite available. Then, we need to decide the yacht requirements and optimize the main dimension of the yacht with regard to ship design concept. The designed yacht will accommodate 2 crews and 6 passengers, the type is 17 ton sailing pleasure yacht with fiberglass as the hull material and equipped with sail as major propulsion and motor for alternative propulsion, it will be used for pleasure around the Poteran Island. The main dimension are: Lwl = 13.680 m, Bwl = 4.958 m, T without keel = 0.623 m, which has 4.025 kN of total resistance estimation when the speed reached 8 knot. After the calculation we design a lines plan and general arrangement of the yacht which is appropriate with market demand and hydrodynamic aspect of Indonesian sea. Finally, we calculate the cost estimation required to build a 14 m sailing yacht. Based on the analysis we can conclude that the yacht industry is feasible if developed as tourism pleasure yachts in Indonesia with the total cost estimation is Rp 1,950,631,000 or about $ 150,049 USD.

The research focuses on using the virtual reality technique to provide a way for users to adjust the interior decorations based on their demands. Since there is a trend of customization of yacht design, we would like to enhance the additional value for manufacturing the yachts. The contents of their research cover changing the furniture and light, and movement of users. We expect the result of our research could help users feel and understand the feeling of walking through their ships during the designing stage. Also, we transfer our result into the mobile devices expecting to expand more flexibility in this area. We use the graphic software 3DS MAX to build the yacht model. Furthermore, we design numerous kinds of furniture or decorations for users to choose. Since the computational ability for smart devices is still lower than personal computers, we simulate the high-poly models effect by using low-poly method and make the UVmap by PHOTOSHOP to maintain the reality of models. Finally, We used SHIVA3D to make the interacting program, which could help users look through the appearance of yacht and the interior rooms, and provide the function of changing furniture. In the end, we compile the program with different versions and install them on different platforms.

The present study investigates in a comprehensive perspective the development and planned design prospect of the proposed yacht marina. As the current yacht docking conditions in Taiwan are generally unsatisfactory, it is necessary in our study to first inspect the inconvenient laws based on review ing the existing docking regulations and their restrictions imposed on yacht docking. The investigation is supplemented with a comparison of foreign examples and brings up the unfavorable conditions restricting the development of yacht cruising, and the respective improving solutions required. The study also discusses the future yacht industry perspective and the leisure habit of our citizen based on a number of datasets. It is anticipated that through the advantage of clustering benefits of the industry (Nanxing Yacht Manufacturing Zone) and the promotion of leisure activities, the yacht docking marina business in Taiwan can be significantly enhanced. The present study, based on yacht industry perspective, has analyzed the necessity of a yacht marina and its benefits on associated industries, and the unfavorable consequences that could probably be generated from the constructionof the marina such as its impacts on natural, ecological and living environments, and discusses the mitigation measures by environmental engineering. The transformation of the fishing marinas in Badouzi, Wushi and Wuqi, on the other hand, is one of the policies under the "Coastal Rehabilitation and Fishery Development Project" actively executed by the government, and the study has carried out various baseline evaluations on all possible scenarios as aresult of this transformation. Chapters on "Assessment of the current conditions of the yacht marinas in Taiwan" and "The design planning of an ideal yacht marina"conclude the study. The former summarizes the opinions and proposed improvement measures provided by related government officials, scholars and businesspersons while the latter proposes various blueprints and substantiated development management concepts of an ideal yacht marina based on consultation of extensive references and foreign examples.

There has been a significant increase in the installation and use of power electronic equipment on board ships installations. The operation of this equipment has in many cases significantly degraded the ship electrical power quality to such an extent that measures have to be implemented in order to minimize the resultant adverse effects on the electrical plant and equipment. This paper aims at presenting a methodology for single-tuned filter design particularly for shipboard applications for suppressing harmonics in accordance with marine harmonic standards. The unique feature of the developed filter design model is that it incorporates both the filter capacity and resonant point as design parameters. The model also considers parallel generator operating modes of the vessel and associated electrical power demands and includes calculation of harmonic voltage distortion, which enables the detailed examination of each individual, as well as the total harmonic distortions, and also recommends filters with specifications appropriate to the system. A practical ship power system with existing harmonic problems was selected to demonstrate and validate the proposed approach through numerical simulation and field test. The analysis model developed can aid engineers to plan similar means of harmonics mitigation early in the design stage of the electrical power distribution systems tomake the system reliable and secure.
