The ferry service that transports people and vehicles between Shelter Island and North Haven, Long Island, will expand by the end of March.
A 101-foot long, 40-foot wide boat will join four others in the South Ferry fleet.
The private ferry company will also begin to replace an existing maintenance dock on Shelter Island with a larger one to accommodate bigger boats.
South Fleet has received federal funding to raise the road that meets the ferries and install a drainage system in North Haven.
