... Two boats sailing in close proximity may inevitably compare their boat speeds, perhaps even "race" each other. Over the last few centuries there have been numerous handicap systems designed to equalize the competitive chances of racing sailboats. Corollary to handicapping is another arcane art...

... In order to sail 470 faster, authors consider the sailing performance of 470 from the various measured data and the simulated results of VPP (Velocity Prediction Program). This is a summary of TOBE-470 presented by the author. INTRODUCTION The 470 (Four-Seventy) was designed in 1963...

... on average faster may not necessarily mean winning the majority of races. This papers present the development of software to compute a sailing strategy for a match race that can defeat an opponent who is following a fixed strategy that minimizes the expected time of completion of the race. The proposed...

... The thrust of this paper is, first, to attempt to define the relationship between the individual sails, both together and separately, and the hull with somewhat more precision, and secondly, to develop a calculation tool to better establish this relationship, and to better anticipate...

... Virtual Sailing (VS) has been producing the world’s only ride-on sailing simulator for 10 years. Based on fundamental principles of sailing dynamics the underlying simulation has shown great robustness permitting significant R&D to be performed and retrofitted to existing simulators...

... US Sailing, the Offshore Racing Council (ORC), the Glenn L. Martin Wind Tunnel (GLMWT), Quantum Sail Design Group (QSDG), the Wolfson Unit and North Sails have collaborated on a series of wind tunnel test programs to investigate the performance of both upwind and offwind sails. These programs...

.... This yacht was built as an amateur project and holds the world record for speed in a land yacht at 116.7 mph. It appears that it is, currently, the fastest sailing yacht on any surface. Finally, the paper provides perspective on a variety of aspects of speed sailing on dirt and ice. high speed mph...

... The primary purpose of this offwind sail investigation was to better understand the relative performance of symmetric spinnakers flown from conventional poles and asymmetric spinnakers flown from conventional poles or sprits, i.e. poles restricted to the centerline. The specific goal...

... The primary purposes of this offwind sail investigation were to better understand offwind sail performance and to improve the ability to predict the performance of specific offwind sail shapes over a broad range of operating conditions. The study was designed to allow sail designers to answer...
