The Nelson/Marek 68 is a maxi-class IOR racing yacht designed by Bruce Nelson and Bruce Marek of Nelson/Marek Yacht Design in the early 1980s. Built as custom one-offs in 1983–1984, the 68 carries a tall masthead rig (I=72.5, J=22.5, P=65, E=21.75) over a long waterline of 59 feet, displacing about 24,300 lbs. Configured for grand-prix offshore racing — Bermuda Race, SORC, Maxi events — the 68 represents the high end of Nelson/Marek's late-IOR work before the firm transitioned to IMS-era designs and Bruce Nelson moved into America's Cup design.
