[1][2] Early work on the class began in August 2014, after a study into the future of Staten Island Ferry's fleet showed that the most economical course would be new-build ships instead of rebuilding existing vessels.
[4][3] The following month, substantial funding for the project, covering the construction of two ships, was secured with a $191.6 million federal grant from the Hurricane Sandy relief bill.
[6] In November 2016, Eastern Shipbuilding was confirmed as the low bidder for constructing the ships,[1] and the shipyard was awarded the contract with a notice to proceed on March 1, 2017.
Some of the parts for the first two Ollis-class ferries were being manufactured at Eastern Shipbuilding's shipyard in Panama City, Florida, which had been severely damaged after Hurricane Michael that month.
[2][14] They will be powered by four EMD 12-710 diesel engines arranged in two married pairs, each of which drive a cycloidal propeller at each end of the ship for double-ended operation.
