If you’re looking to reach affluent New Yorkers, you might consider a lavish outdoor campaign on upper Fifth Avenue or something in the Hamptons. But another option would be on the Staten Island Ferry.

Forget the stereotypes of Staten Island as Archie Bunkerville. It turns out to have the highest median income of all the New York boroughs, $64,333, according to the 2000 Census. Staten Islanders are also likely to have more degrees and own more cars.

Every day about 65,000 Staten Islanders make the 25-minute commute to Manhattan on the 103-year-old ferry, which has been free since 1997. Including tourists and others who also use the ferry, the five boats transport 80,000 passengers a day on average, or about 1.4 million a month.

Advertising on the ferries is relatively straightforward, with indoor and outdoor signage on each of the boats’ three decks. The signs measure either 21 by 33 inches or 21 by 22 inches, and creative must be approved by the city Department of Transportation.

“The minimum we suggest is 25 boards, giving you five on each boat,” says Francine Ranzi of FerryAds.com, which handles ad sales for the Staten Island Ferry.

She says the ferries feature mainly local advertisers right now but they're open to regional and national advertisers as well. The minimum buy is a 12-week run, but there are also 24- and 52-week options available.
