Notes: In addition to the taller rig and increased ballast, this model featured a redesigned rudder which accounts for it's greater listed water line length.(unmeasured by the IOR) Later still, the interior was changed which included, among other details, an extended port side settee with removable dinette.\nAfter Yankee Yachts went out of business in 1975, a few boats were built by Heritage Boat Works and Vashon Island Boat Works, both of Oregon, USA. (Rig dimensions listed here are from the MK III published sailplan though they are not necessarily consistent even within this particular version.)
