Production
The design was initially built by Geraghty Marine, who built two boats as the Nelson Marek 55, and then by W. D. Schock Corp, who acquired the molds and also built two boats as the Schock 55, with production running from 1990 to 1991.{{cite web|url= https://sailboatdata.com/builder/schock-wd|title= Schock W.D.|access-date= 18 August 2022|last= McArthur| first= Bruce |work= sailboatdata.com|year= 2022|archive-url= https://archive.today/20200718211515/https://sailboatdata.com/builder/schock-wd|archive-date= 18 July 2020|url-status= live}}{{cite web|url= http://wdschock.com/history/boatlist.htm|title= Boats built by W.D.

Operational history
In a 1991 review in Cruising World by Quentin Warren wrote, "long and lean, carrying a deep keel and a tall rig, the new 55-foot ULDB offered this year by the W.D. Schock Corporation is a striking Bruce Marek design with serious racing potential and a one-design slant."{{cite web|url= https://books.google.com/books?id=HxBBldfR2KgC&pg=PA81|title= Showcase '92 |access-date= 18 August 2022|last= Warren|first= Quentin|work= Cruising World|date= September 1991}}
