Producers of the Broadway musical “Dames at Sea” are abandoning ship, posting a closing notice for early January following several weeks of struggle at the box office.

There’s no official confirmation about the show that will jump into the vacancy at the Helen Hayes Theater, but smart money’s on “The Humans,” the Stephen Karam play that’s in the midst of a much-lauded Off Broadway at the Roundabout Theater Company. A team of producers led by Scott Rudin is angling for a spring slot on Broadway for the production, which would fit nicely into the Hayes, one of the more intimate Broadway houses at less than 600 seats. Response for the Off Broadway bow has proven strong enough that the play looks poised to become a serious contender come awards season.

A revival of a 1966 spoof of the Busby Berkeley-style musicals of the 1930s, “Dames” earned a batch of mixed (if often affectionate) reviews. Weekly grosses have only once cracked the $250,000 mark, and for the week ending Nov. 15, attendance slipped to just 60% of overall capacity.

“Dames at Sea” will shutter Jan. 3, holding out for a sales spike over the Thanksgiving and Christmas frames. Producers are at work on a national tour of “Dames at Sea” that will launch in 2017.

Directed and choreographed by Randy Skinner, “Dames at Sea” is produced by Infinity Theatre Company (Anna Roberts Ostroff & Alan Ostroff), Martin Platt & David Elliott, Patricia M. Roberts & Bert C. Roberts, Carl Berg, Louise H. Beard, Julie Boardman/Sarahbeth Grossman/Minerva Productions LLC, and Douglas & Steven Maine/Chris & Dawn Ellis.
