New NYC Ferry Vessels Sidelined by Corrosion

Just six months after going into service, six of New York City’s new commuter ferries are undergoing repairs to address corrosion.

NYC Ferry, which launched in May, includes 20 catamarans; three are reportedly undergoing repairs related to corrosion.

In response to an article published Sunday (Nov. 26) in the New York Post, the New York City Economic Development Corporation tweeted that three boats are currently undergoing repairs in order to adjust their keel coolers. These mechanisms, mounted on the outside of a boat, act as heat exchangers, cooling fluid and sending it back to the engine to maintain temperature.

The Post reported that there were holes and leaks on five ferries as a result of the corrosion; Hornblower initially told local news channel PIX 11 that it was only three boats that were affected, and while the corrosion could have led to holes if untreated, there were no holes present when the issue was discovered during routine inspections.

An EDC representative told PaintSquare Daily News Tuesday, though, that in addition to the three boats already undergoing repairs, three more were pulled Monday. One is simply being taken out of service as a precaution, the organization said, while the other two have "pin-prick sized holes in the hull." 

EDC's statement on the issue did not include information about the coatings used to protect the hulls.

Keel Cooler Issues

The NYCEDC oversees the NYC Ferry system, which is run by Hornblower Cruises, a company based in California and New York. Hornblower will reportedly cover the cost of repairs to the boats, and no taxpayer money will be used to make the fix.

The keel coolers on the boats were reportedly aligned incorrectly, causing what the Coast Guard described as pitting on the aluminum hulls.

New Service

The NYC Ferry began operation in May, with a fleet of 20 catamarans, each 26 meters. According to the company, the vessels employ a “vinyl coating in lieu of toxic solvent-based paints.”

Owing to high demand, the service is reportedly slated to add vessels in the coming year.

Sometimes those " toxic solvent -based paints " are just better. You pay the price for being green. Excellent example thereof.
