Keystar Construction, a family-owned general contractor based in the Florida Keys, has signed on to support Race World Offshore, the Friday Night Duval Street Party and the Key West World Championships.

The company provides general contracting and construction management services, with past projects including the Florida Keys Aqueduct Authority Headquarters, Frederick Douglass Community Center, Garden View Apartments, Key West International Airport and Signature Aviation of Key West.
The deal adds to a growing list of local businesses attaching themselves to race week. Pier House Resort & Spa opened its waterfront Sunset Terrace as a viewing spot for the championships, while Blue Marlin Motel joined the 2026 sponsor lineup with accommodation just off Duval Street.

As with those arrangements, there's no word yet on results, standings or team news tied to the sponsorship itself. Key West's hospitality, retail and construction businesses are increasingly hitching themselves to Race World Offshore's championship week, much as Courtyard by Marriott Key West did when it locked in accommodation for teams, crews and fans heading to the Florida Keys for next season's racing.
