Over the past few years, I’ve been harsh on politicians who have opted to trumpet proposals for ferry service as a cure-all for the city’s congested transit networks, and Mayor de Blasio’s so-called five-borough ferry service was no exception. He unveiled the idea during his State of the City speech last week, and I tore it apart on Thursday.

Simply put, the mayor’s proposal is an expensive way to subsidize travel for the few people who both live and work along the city’s waterfronts, and most of those people have chosen to live in luxury housing on the water front knowing commutes may take a little longer. With the exception of the Soundview and Red Hook ferries, the New Yorkers who need the most help — the middle and lower classes in transit-poor areas — are left out of the mayor’s idea, and it falls short as a solution.

But if we step back for a few minutes and ignore the way ferries cater to NIMBYs by leaving car lanes, parking spots and lengthy and disruptive heavy construction projects to the side, we may be able to save parts of the ferry proposal. It takes creativity and work, and it would take some rethinking of road space and transit prioritization. It also doesn’t overcome the fact that a ferry service that costs the same as a MetroCard swipe is subsidized to the tune of $15-$30 per rider, but it’s a start.

1. Integrated Fare. No matter how much money the city is willing to sink into the ferry system, they won’t get significant buy-in from residents who have to pay two fares. Those who are willing to use the ferry system to save time won’t be so keen on paying a $2.75 fare for the ferry and another for connecting modes of transit on the other side. This of course involves cooperation between the city and the MTA, and although the MTA has not embraced the ferry proposal or any integrated fare system, a free transfer between boat and bus or boat and subway would do wonders for ridership and mobility.

2. Integrated Surface Transit System. Ferries on their own aren’t that exciting if the way to get them involves walking and hoping that some other transit system serves the ferry terminal. Along with a ferry system, the mayor should have announced an extensive feeder bus system that delivers riders to ferries and then brings them to their destinations on the other end as well as expanded CitiBike access at ferry stations. The 34th St. Transitway and Vision42 remain the pinnacle of hopes dashed for river-to-river access, and both would do wonders for the mayor’s ferry system. Select Bus Service or BRT routes to and from ferry stops would be acceptable. CitiBikes, which admittedly implicate other issues of integrated costs and fare payment systems, should be readily available at ferry terminals as well. Instead, the mayor’s proposal didn’t even acknowledge that getting to a ferry terminal is just as important, if not more so, than the ferry system itself.

3. The Subsidies Are Too Damn High. As I mentioned, despite the attempts at saving the ferry system, someone needs to justify the subsidies. Considering who the likely riders are and where the routes run, the subsidies are even less palatable. Why must they be so high? What can the city do to bring them in line with at least express bus service, already the highest subsidized mode of transit within the five boroughs? Should we even accept high subsidies without further question?

Even trying to save the ferry proposal rings hollow simply because it’s not going to do much to solve the MTA’s capital budget woes, its constant signal problems or overcrowding on numerous lines. It’s not going to get high-speed service to neighborhoods that rely on local buses at best. It’s a nice thing to have for some people, but for most, it’s an afterthought and another proposal from another politician uninterested in tackling the harder questions relating to transit access and funding.

Another year, another New York City politician jonesin’ for some panacea of citywide ferry service that won’t solve any problems. This time, the honors belong to our Mayor who, in his State of the City speech earlier this week, promised 13 bus rapid transit routes by the end of 2017 and six new ferry routes over the next few years. He later said on NY1, apparently without joking, that he feels the ferry service can alleviate subway crowds.

As far as ferries go, I’ve written about this topic more times than I care to revisit, but here we are. Politicians latch onto it because it’s easy. Adding ferry service doesn’t involve taking away an oh-so-precious lane of parking or — gasp! — driving and it doesn’t involve a multi-billion-dollar layout of cash that leads to disruptive and lengthy construction. It sounds good — because who doesn’t like boats? — and gets people talking because it’s different. Despite de Blasio’s claim, it won’t do one iota of good for subway service and doesn’t solve the intertwined issues of funding, congestion and reliability currently plaguing our aging transit network.

But let’s look at what de Blasio said. During his speech, he announced the idea: “Today, we announce that we’re launching a new citywide ferry service to be open for business in 2017. New ferry rides will be priced the same as a MetroCard fare, so ferries will be as affordable to everyday New Yorkers as our subways and buses. Residents of the Rockaways and Red Hook and Soundview will now be closer to the opportunities they need, and beyond connecting residents to jobs in Manhattan, our new citywide ferry system will spur the development of new commercial corridors throughout the outer boroughs.”

Later, his office released details on the funding plans. The map you can see above, and while the heavy lines demarcating preexisting service make the plan look more all-encompassing than it is, it’s stretching the boundaries of viable ferry service. de Blasio said the city will provide operating support, though the amount of subsidies aren’t yet clear, and will spend $55 million on capital commitments. The Coney Island-Stapleton-Wall St. route that will, on the leg between Brooklyn and Staten Island, attract approximately no riders wasn’t included in this cost projection.

As long-term readers know, I’m not a fan of this infatuation with ferries, and I’ll get into that in a minute. First, though, let’s stop to acknowledge that ferry service can be useful. It’s a complementary element of a robust transit network that can bridge awkward gaps. The service from Astoria Cove — a new development nearly a mile away from the subway — can bring residents who work at Manhattan’s East Side hospitals to their jobs. The service from Bay Ridge to Wall St. would be more useful with a stop at Industry City, but it too can solve a problem.

That said, no matter how many times politicians leap to embrace ferries, the same problems remain. It is, flat out, not a substitute for subway service and, because of the scale of ridership figures and planned routing, won’t help alleviate subway congestion. If it takes a few cars off the road, so much the better, but the mayor should be looking at high capacity solutions to the city’s mobility problems. Simply put, ferries aren’t the answer, and now, I’ll explain why.

1. Connectivity

A good transit network connects homes and offices. On a good night, I can leave work and be home in 30 minutes, and my ride is a zero- or one-transfer, one-fare journey. The utility of any transit network should be based on that concept, and the ferry system falls flat. It may be a nice way to travel, as many defenders have pointed out, but it doesn’t really connect people’s homes and jobs. At best, it serves those folks who live on the Brooklyn waterfront with their jobs at Wall St. which brings me to….

2. Poorly Placed Subsidies

It’s never cheap to operate a ferry network. In fact, the Rockaway ferry was running the city as much as $30 a passenger in subsidies. With the exception of the Soundview and Rockaway ferry proposals, the mayor’s routes by and large connect to areas of people who can afford waterfront housing and bring them to their high-paying jobs in Wall St. and Midtown. This reeks of a subsidy for people who don’t need subsidies. Is that how to solve concerns about middle class viability in New York City, as the mayor stressed, and mobility?

3. The Fare Structure

In effect, the fare issues are a subset of points 1 and 2. The mayor wants an affordable fare, which is a commendable goal, but he won’t be able to ensure one-fare rides or a transfer between ferries and subways and buses. The MTA hasn’t expressed any willingness to forego revenue for the sake of a city-run ferry network, and I don’t blame them. Thus, anyone trying to get from a ferry stop inland is looking at a two-fare ride, and few New Yorkers want to subject their wallets to a double dip like that.

4. The Rockaways, Again

A crazy part of this specific proposal is the Rockaway ferry route. For some reason, this has become a hot-button political issue in a neighborhood that de Blasio would love to see vote for him in 2017. Amusingly, though, the mayor canceled this very same Rockaway ferry route four months ago because it was too expensive and nobody rode it. What will change between now and 2017? Probably nothing except that the mayor will be up for reelection. Color me skeptical.

5. Ferries Aren’t A Solution

For $55 million in capital funds and, optimistically, $20-$30 million in annual operating costs, the city could do wonders for the bus network. Instead, de Blasio is spending his political capital on a system that likely won’t see daily ridership exceed that of 1 or 2 peak-hour subway trains. These routes — most of which don’t parallel subway lines and aren’t faster that the trains — won’t alleviate congestion as subway ridership continues to climb at steep rates. In fact, the ferry plans take away from a real debate on sustainable funding, political support for transit and high-capacity growth.

So there you have it: one thousand words on ferries at a time when literally no politician wants to tackle issues of cost control, congestion pricing or capital plans. That’s de Blasio’s New York for you.
