TECHNICAL PAPERS

• An alternative approach to the design of structures exposed to slamming loads
  The past twenty years have seen significant progress in the performance of motor and sail yachts, which has been partly driven by the use of polymeric composite materials. The science of structural design has moved forward in parallel.
• Challenges Associated with Design and Build of Composite Sailing Superyachts
  The composite sailing yacht market is developing at a fast pace. Large ocean-going cruising yachts are capable of record breaking performances thanks to the continuing development in technology, materials and design, yet they are also required to have a luxurious fit-out. Composite materials can offer significant advantages when performance is part of the design brief
• Comfortable Structure, 3rd High Performance Yacht Design Conference, 2008
  In today’s competitive design environment, it is not enough to design a yacht focused purely on meeting technical design aspects such as speed, handling and seaworthiness. In most cases, whether a cruising yacht or a racing yacht, owners want a yacht that is functional, comfortable and elegant.
• Development of Production Orientated Advanced Composite RIBS
  Advanced composites using epoxy resin and carbon fibre reinforcements can bring a number of benefits to RIB manufacture making it possible to build lighter, stiffer structures leading to higher performance.
• Measurement of accelerations and keel loads on canting keel race yachts
  Canting keel boats can offer a significant increase in the performance of monohull yachts. Canting keel structures have generally been designed using a quasi-static analysis under a range of load cases. SP has developed load cases and analysis techniques for canting keel structures which have been used successfully for a range of yachts.
• Sink or Swing - The Fundamentals of canting keel structures
  The paper identifies the unique loading imposed on a canting keel under slamming accelerations, which lead to much higher cyclical and peak transverse loading on the supporting structure than would be experienced with a fixed keel. Better understanding of this fact by designers would greatly reduce canting keel system failures.
• Superyacht Structure Insights
  This booklet is intended for interior designers and naval architects, aiming to help create a simpler structural design at an early stage of a superyacht project. The challenges faced by the structural engineer behind each compromise are highlighted in each section, but the focus is on practical suggestions, rather than technical explanations.
• The Advantages of Composite Material in Marine Renewable Energy Structures
  Paper presented at RINA Marine Renewable Energy Conference 2008, Composite materials can have many advantages when they are used in marine renewable energy structures. These advantages will be demonstrated in this paper with an example of a 2m prototype of a C-Power Underwater Turbine that was engineered and built at Gurit using composite material.
• Work load to break load - Safety factors in composite yacht structures
  The loads imposed on yacht structures fall broadly into two categories: the distributed forces imposed by the action of the wind and waves on the shell of the yacht, and the concentrated loads imposed by the rig and keel to their attachment points on the structure. This paper examines the nature of the latter set of loads and offers a methodology for the structural design based on those loadings.
