Supporting SYRF Yields Results

A donation made to SYRF yields results 

2016 was a very active and productive year – your continued generosity helps SYRF’s mission to support the scientific research used to improve handicap sailing 


Newport, RI – This year’s activities in projects supported by the Sailing Yacht Research Foundation (SYRF) were numerous and wide-ranging:
  •  SYRF was a co-organizer of the triennial Chesapeake Sailing Yacht Symposium, helping bring dozens of students and researchers from all over the world together at the US Naval Academy for two days of presentations on research topics and projects being pursued in sailing science and technology;
  • Using the services of vendor KND Sailing Performance, SYRF supported a program of data log analysis to assist both owners and handicappers in better understanding of the precise conditions of weather encountered in select inshore and offshore races, where the results were used to calibrate instruments and give a more accurate understanding of boat performance in these conditions;
  • Phase 1 and Phase 2 of the Downwind Aero Moments and Forces were proposed, approved, researched and reported, with the results loaded to the SYRF Library and discussed just last week in the first public facing webcast made with researchers JB Braun, Michael Richelsen, and Mike Schrieber of North Design and hosted by SYRF. Eighteen attendees on this call were able to listen to explanations of the methods used in this study, and also able to pose questions to Braun and Richelsen in an online forum. Another webcast is organized for next month to review the results of Phase 2C of this project.
  • At the beginning of the summer season SYRF provided administrative support for a project to use empirically-derived polar performance data of large multihulls to analyze results in select inshore races in the so-called Multihull Rule Project. This project is still being shaped by project manager Larry Rosenfeld with the goal to achieve better and more accurate handicapping of these large yachts using an objective scoring method called Performance Curve Scoring;
  • Based on these projects, Executive Director McKenzie Wilson made a presentation on data collection technologies at the Design and Technology Symposium of the Yacht Racing Forum held in Malta, where this and other SYRF projects received widespread exposure to an international audience of sailors, designers, researchers and media;
  • The Wide Light 2 project to study the performance of modern high-speed offshore boats has also made progress, with designers on the SYRF Advisory Council contributing their knowledge to develop a parent hull shape suitable to put through the suite of CFD testing identified as most productive in the Wide Light 1 study. A 14 m hull shape has been chosen by SYRF Technical Director Jim Teetersas the base for further testing.
    This 14 m hull will be uploaded to the SYRF website and SYRF encourages open collaboration within the yacht design community on sharing CFD results;
  • The first phase of P-Cubed (Performance Prediction Project) is now underway. The goal of this first phase is to explore tradeoffs in accuracy between using a panel and a RANS CFD code in predicting a sailboat’s performance through its sailing wind range. Because panel codes are generally much less expensive to run, the plan is to compare North Technology Group’s “Flow” panel code versus the RANS code “OpenFOAM” over a sweep of apparent wind angles to quantify the limit to “Flow” for generating accurate and comparable data. North, not SYRF, will fund any developments to “Flow” needed for this study.
    Phase 1 of P-Cubed will provide guidelines for which data points can be generated by a panel code and which data points may necessitate the use of RANS against a documented and acceptable trade-off in accuracy. The target completion date for Phase 1 is June 2017.
  • Ongoing work is also being done to improve the SYRF website and the SYRF Library to make it more interactive and usable for researchers, students, and others with an interest in aero- and hydrodynamic research.
  • And SYRF is in regular contact through the Advisory Council and technical meetings to ensure the world’s science-based rating systems are aware of the progress being made in SYRF-funded research so that they may use this data to improve the accuracy of their handicapping.”There are over 17,000 boats around the world that race using a measurement-based scientific rating system,” says SYRF Chairman Steve Benjamin. “Our work in supporting the research needed to help improve these systems is therefore important to an enormous number of sailors and race managers, whether they compete at the local or world-class levels. Having your support will help not only these systems to provide more accurate and fair ratings, but also yourself in seeing this game improve and grow, providing a better value for all who sail.”
