Welcome to the Chesapeake Sailing Yacht Symposium (CSYS) home page

The Chesapeake Sailing Yacht Symposium is the world's longest running technical forum dedicated to advancing the study of the art and science of sailing yacht design technology.

Professional yacht designers and a wide variety of sailing enthusiasts travel from around the world to attend the CSYS Symposia to present papers and exchange ideas on sailing.


The Twenty First CSYS was a terrific success, with sixteen presentations by authors from around the world. On Friday, the more technical papers were presented and included studies of sailboats using towing tanks, wind tunnels, field measurements and computational modeling. Prof. Lex Keuning surprised many in the audience with his announcement that Delft University will now make the entire raw data sets from each of their Systematic Yacht Hull Series available to the public, online and at no cost – www.dsyhs.tudelft.nl

The presentations on Saturday were aimed at a broader audience, including subjects ranging from traditional sail training ships to “Footy” model sailboats. One presentation showed wind tunnel measurements of the wind field around sailboats in close proximity that could help a skipper decide how to pass another boat. Annapolitan Britton Ward from Farr Yacht Design wrapped up the symposium with an overview on the development of the new Volvo One-Design Class, showing how the class has evolved and why it has headed in a new direction.

About one hundred people attended the symposium, most with technical backgrounds and all very interested and enthusiastic about advances in sailing technology. Among the audience were local sailors from Annapolis, researchers who travelled from as far away as New Zealand, a group of students from Webb Institute, and sailing legend Dawn Riley, who chatted freely with authors and attendees during breaks and at the closing reception.

Papers from past symposia are now being integrated into the SNAME “20 Free Download” database so that papers will be easier to access. Don’t miss your opportunity to attend the next CSYS (dates TBD) where you can meet with the people who are moving sailing yacht technology forward!


Fair winds and following seas...

Capt. Richards Thorn Miller, USN (Ret), a retired naval architect and engineer, died December 7 at Baywoods of Annapolis. He graduated from the Webb Institute of Naval Architecture in 1940 with a bachelor of science degree in naval architecture and marine engineering, and he received the degree of naval engineer from MIT in 1951.

During WWII he served as Assistant Hull Superintendent, building the battleships IOWA and MISSOURI at the New York Naval Shipyard 1940-41, and Assistant Supervisor of Shipbuilding, Annapolis, responsible for inspection of the construction of submarine chasers, PTs and other small craft in ten yards in the northern Chesapeake Bay and lower Delaware Bay areas 1941-45.

He was an honorary member of the U.S. Naval Academy Class of 1941. He wrote a number of articles on ship design matters, co-authored a book on sailing yacht design, and was co-founder of the Chesapeake Sailing Yacht Symposia. His memberships included the Society of Naval Architects and Marine Engineers (SNAME) of which he was a Life Fellow and Honorary Vice President, the American Society of Naval Engineers, the United States Naval Institute, the Society of Sigma Xi, the Christie Society of the Maryland Board for Professional Engineers, the New York Yacht Cub, and the Annapolis Yacht Club. His awards included the Navy's Legion of Merit, SNAME's Capt. Jospeh H. Linnard Prize, and the Webb Alumni Association's William Selkirk Owen Award.
