Edy Walsh
1949-2003
Frederick Wallace wrote:
"Ye can have yer steamboat racin', but gimme the run in a gale, Of a well geared, able clipper, what is driven by snow white sail.
For I've known the thrill of a pilin' sea an' the sky in cloud flecked gown A n ' fourteen laiots in a windbag when she's running her Easting down." Edy Walsh is that well geared, able clipper, driven by snow white sail
These gifts were showcased every two years at the Chesapeake Sailing Yacht Symposium, for which she was the Arrangements Chair. This Symposium is the premier technical forum in the world for sailing yacht technology and regularly draws international papers and attendees. Authors from England, France, Spain, Italy, Germany, Holland, Switzerland, Argentina, Japan, Australia and New Zealand are commonplace. A l l attendees perennially appreciated the venue, snacks, meals and receptions, which Edy orchestrated. Everyone, including some of the most well known names in the sailing world, knew her and were delighted to see her again. She needed a sailbag sized for a spinnaker on a 70 foot long International America's Cup Class yacht to carry home all the compliments she received each time
