Inaugurated in 2020, the Sandusky 45005 (originally the Vermilion 45005) was organized as a singlehanded sailing event to give sailors on Lake Erie, who may have been considering entering a GLSS-sponsored singlehanded challenge, an opportunity to sail a course of manageable length with a fleet of other singlehanded boats. The event utilizes NOAA Weather Buoy 45005 as a mark on the course (hence the name of the event), along with a mark at Huron Harbor entrance, and a start/finish area near the Sandusky Pierhead Light to create a triangular course about 41 NM long.
