Internal waves are responsible for many important processes in the ocean environment (ocean ventilation, energy transfer from large-scale to turbulence, etc.). Our goal is draw attention relatively little studied effect of internal on ships at sea. We encountered this times while working study shelf zone. The work was carried out a yacht equipped with “Rio Grande 600 kHz” ADCP, which makes it p...

As an alternative to mass tourism, yacht charter services are preferred by Families. Although it was young people who were used the outdoor lifestyle initially for sailing, swimming and sportive activities, nowadays is families with increasing comfort on yachts. In study, effects of current developments, customer preferences, market developments in types have been examined. Observations made so...

In some specific environmentally protected areas, conventional mooring systems cannot be used by large yachts for stationing at anchor and therefore, the adoption of a dynamic positioning system is required. It becomes then necessary to evaluate station keeping capabilities yacht since early-design stage. Adopting quasi-static approach, it possible perform standard capability analysis, as commo...

Since 1994 the Australian Maritime Engineering Cooperative Research Centre (AME CRC) has conducted an extensive set of towing tank experiments and theoretical predictions for calm and rough water, on a series of 11.3 metre IMS style racing yacht hulls with varying form parameters. In collaboration with Murray, Burns & Dovell (MBD), the AME CRC has developed a Velocity Prediction Program (VPP), ...

Non-oscillatory discretization methods based on the Local Extremum Diminishing principle, which were originally devised for compressible flow, are applied to the free-surface evolution equation. More specifically, both symmetric and upstream limited schemes are utilized in the calculation of the flow about the Series 60 hull, a naval frigate hull with sonar dome and transom stern, and a fully c...

We consider the problem of finding a route that minimises the expected sailing time between two points on the ocean under uncertain weather conditions. This has applications in long distance offshore yacht racing. The uncertainty in the weather is modelled by a branching scenario tree that captures the serial correlation inherent in the evolution of weather systems over time. The stochastic sol...
