The powering requirement of a land yacht is one of the most important aspects of its design. In this respect the wind tunnel testing is an effective design tool. In fact, changing the parameters of the vehicle and testing the changes in the wind tunnel will give us a better understanding of the most efficient vehicle, and yet it is time consuming, expensive, and has inherent scaling errors. Ano...

A 5 year research program to investigate the effect of realistic hull form parameters on the added resistance of a yacht in waves is nearing completion. Model experiments and theoretical predictions were carried out and the results are discussed in this paper. Five hull form parameters have been investigated so far, they are: 1. stern overhang; 2. LCB-LCF separation; 3. prismatic coefficient, 4...

We consider reasoning about prefactual possibilities in the future, for example, "if I were to win the lottery next year I would buy a yacht" and counterfactual possibilities, for example, "if I had won the lottery last year, I would have bought a yacht." People may reason about indicative conditionals, for example, "if I won the lottery I bought a yacht" by keeping in mind a few true possibili...

Autonomous land yachts can play a major role in the context of environmental monitoring, namely, open, flat, windy regions, such as iced planes or sandy shorelines. This work addresses design, modeling, and simulation yacht probe equipped with rigid free-rotating wing sail tail flap. The was designed symmetrical airfoil dimensions to provide necessary thrust displace vehicle. Specifically, it p...

Motion sickness experiences were obtained from participants in a 9 month, round the world yacht race. Race participants completed questionnaires on their motion sickness experience 1 week prior to the start of the race, during the race, and following the race. Yacht headings, sea states, and wind directions were recorded throughout the race. Illness and the occurrence of vomiting were related t...

There are many factors that can determine the winner of a yacht match race. The major factors include weather conditions observed during the race, tactical decisions made while sailing and the dynamic performance of each yacht. Weather conditions observed during the race can be modelled from actual weather data. Tactical decisions made while sailing can be modelled using logic that approximatel...

Robert Braithwaite, CBE, founded Poole-based Sunseeker Boats in 1968. Its fi rst model was a 5-metre yacht. Today, its biggest yacht is over 37 metres long; some have top speeds of 60 knots. In a typical year, it sells several hundred new yachts. Depending on specifi cation, prices are upwards of £250,000. Sunseeker is presently the largest volume boat builder in the United Kingdom (UK) and one...

This paper describes an analysis of Yacht Simulator international trends and also explains about Yacht. The results are summarized as follows. Attached to the cockpit are sensors that feed -back information on rudder angle, boat heel angle and mainsheet tension to the computer. Energy expenditure of the sailor measure indirectly using expired gas analysis for the measurement of VO2 and VCO2. At...
