Article
Full-text available
The forthcoming publication of the revised BS EN ISO 12215-5 is set to transform the structural design of most small crafts for the next decade, with the implementation of significant changes to the scope and underpinning theory, such as an applicability extended up to 24 m Load Line, and the use of finite element methods as part of the compliance...
Article
Full-text available
Despite the omnipresence of hydrofoil-assisted racing monohulls and the inherent development phases to refine their designs, very little scientific data has reached the public domain. Moreover, following the trend set by racing yachts, the cruising industry is now looking at the implementation of foils onto leisure vessels, with several already bui...
Article
Full-text available
Over the past two decades, the numerical and experimental progresses made in the field of downwind sail aerodynamics have contributed to a new understanding of their behaviour and improved designs. Contemporary advances include the numerical and experimental evidence of the leading-edge vortex, as well as greater correlation between model and full-...
Article
Full-text available
The flow around a circular arc is governed by the effect of the sharp leading edge and by the arc's curvature. There is a range of incidences where a leading-edge separation bubble (LESB) is formed on the convex side of the arc, and the reattached boundary layer separates further downstream. Akin to foils and cylinders, for increasing values of the...
Article
Full-text available
Timber construction has recently seen a significant regain of interest across a range of industries, owing to contemporary concerns for sustainability. In the marine industry, historic principles of traditional wooden boatbuilding remain present, with empirical rules still common practice, as is the case for scarf joints. Moreover, laminated wood i...
Article
Full-text available
Glass fibre reinforced polymer composites are the most common materials employed for the manufacturing of small crafts, with the scantlings governed by ISO 12215-5:2019. However, no validation data is available to ascertain the relevance of the default ultimate strengths provided by the standard. This paper experimentally characterises the ultimate...
Article
Full-text available
Model-scale testing might suffer from blockage effects due to the finite dimensions of the test section. Measurements must be corrected to predict the forces that would have been measured in unconfined conditions. Blockage corrections are well-established for streamlined and bluff bodies, while more data is needed to develop corrections for bodies...
Conference Paper
Full-text available
Model-scale testing of yacht sails and wings often suffers from blockage due to the physical constraints of experimental facilities. With blockage, a greater increase in flow speed occurs in the vicinity of the geometry compared to an unblocked flow as a direct consequence of the restricted cross-sectional area. This leads to artificially higher fo...
Conference Paper
Full-text available
With the current global warming crisis and contemporary concerns for sustainability, the transport industry is developing and implementing novel solutions to reduce greenhouse gases. With close to 90% of the world's goods relying on maritime transportation, responsible for 3% of global energy-related carbon dioxide (CO2) emissions in 2019, there is...
Conference Paper
Full-text available
Upwind yacht sails, characterized by a low camber and largely attached flow, have long been successfully analysed using inviscid methods. Conversely, inviscid approaches are unsuitable for highly cambered wings, such as those employed for downwind sailing and some wind-assisted ships due to the highly separated flow. Furthermore, despite recent num...

Conference Paper
Full-text available
The spinnaker is the most powerful and one of the most used sails both in racing and cruising - yet its complex aerodynamics governed by flow separation is still not fully understood. While the flow around a spinnaker is unsteady and highly tridimensional, locally the governing fluid mechanics may be represented by the quasi-steady bidimensional fl...
Chapter
Full-text available
Archer, Morley and Souppez critique the value of building authentic assessment to reflect better a real world learning approach that prepares students more explicitly for employment after graduation. The two case studies within this chapter are drawn from the different disciplines of festival and event management and yacht design; both aim to prepa...
Chapter
This chapter offers insight into how ships are designed by naval architects to address the ever-growing demand for maritime transportation. The terminology associated with ships is introduced, together with some of the main design characteristics of ships. The stability of marine vessels at both small and large angles of heel is explored. Furthermo...

The flow around cambered circular arcs with a sharp leading edge is a paradigm that underpins a vast array of cambered thin wings. Yet, some key features of this flow condition, such as the impact of the leading-edge bubble on the boundary layer regime and trailing-edge separation, remain to be fully characterized. Here, particle image velocimetry...
Conference Paper

The rules and regulations inherent to the design pressures and scantlings of high-speed powercrafts are numerous, and regularly reviewed. Recently, the new ISO 12215-5:2019 made notable changes to the way high-speed crafts are analysed, including extending the acceleration experienced up to 8 g in certain circumstances. Nevertheless, despite the mu...

Full-text available
The revised ISO 12215-5 published in 2019 will govern the structural design of small crafts for the forthcoming decade. With an extended scope, applicable up to 24 m Load Line length and now encapsulating commercial crafts, the next generation of powerboats will be heavily influenced by this new regulation, and possibilities it offers. Furthermore,...

The Thames A-Rater fleet is a unique class both in appearance and in its combination of historic and modern technologies. With high aspect ratio, carbon fibre rigs fitted onto wooden hulls, many of which have survived two World Wars, the class is a demonstration of the evolution of sailing technology. In more recent decades, various attempts have b...

Force measurements have been undertaken at low Reynolds number (circa 50k to 220k) on a highly cambered thin circular arc with a sharp leading edge in order to investigate the laminar to turbulent transition of modern asymmetric spinnakers. Evidence of a critical Reynolds number inducing transition has been provided, as well as the existence of a v...

The results of the year-long implementation of micro-lecture captures with embedded quizzes will be presented. The innovative use of lecture capture enables students to accept a short summary video after each lecture, as part of which they need to engage with a series of quizzes. This has proven to be very beneficial to their engagement with the VL...

The contemporary concerns inherent to sustainability have become predominant in a number of industries, including the marine one. In July 2011, the Marine Environmental Protection Committee of the International Maritime organisation (IMO), imposed a reduction of pollutants, such as NOx and SOx, by 90% before 2025, and a complete end to CO2 emission...

In the context of accelerating climate change, people’s attempt to reduce their CO2 footprints and shipping companies' struggles to meet ever-stricter emission regulations, the interest towards sail powered commercial vessels is growing. With this in mind, the preliminary design of a 65ft. wooden sailing cargo vessel will be undertaken, primarily i...

The Thames A-Rater is a Victorian era designed 28ft racing dinghy based on the river Thames. Despite a number of new boats being built in the 1980s the fleet is reducing in size slowly but surely, this may be due to the class rules stating that any new hull claiming to be a Thames A-Rater needs to be an exact replica of an existing hull with all me...

The project consists of two stages: the design of a classic sailing yacht, including all the interior design and the development of a structure that merges wood building and carbon fiber on the more critical areas, then followed by the incorporation of a modern hydrofoil system. The aim of the hydrofoil, adapted from racing yacht technology, is to...

While there is still a strong passion and interest for traditional crafts, many of the designs now need to be adapted to comply with the contemporary rules and regulations, and additional modifications are required to meet modern expectations, in areas ranging from comfort to safety; hence the need for modern replicas. In order to ascertain the con...
