Resolve Marine is fishing for boats that Hurricane Katrina deposited at the bottom of one of the city’s largest marinas where as many as 200 boats are submerged at Municipal Yacht Harbor. Resolve Marine is expected to finish the job in about a month.

The city of New Orleans did not ask for help at the marina until last summer, and it has taken until now to complete the environmental assessments and get through the state bidding process, Hammatt said.

Resolve will also remove an estimated 300 tons of debris from wood pilings to refrigerators to splintered boat parts from the harbor bottom.
