A pirate museum that ignited racial controversy when it was proposed for the downtown Tampa waterfront may return to the city it spurned in favor of Tampa. The New York developers of the Whydah pirate museum said they are considering returning to the original proposed site in the Boston Navy Yard. Boston is offering incentives that include $4-million for improvements, parking and access to low-interest bonds to finance the $70-million project. Paul Barrett, director of the Boston Redevelopment Authority, said he does not anticipate race issues sinking the project in Boston as they did in Tampa. "This project was around Boston for two or three years," he said. But Massachusetts state Rep. Byron Rushing, an African-American Democrat from Boston, is not as hopeful. He questioned the propriety of the project before and told Boston newspapers Wednesday that he would insist his original concerns be addressed.
