The Falmouth company that operates seasonal passenger ferries to Edgartown is proposing a water taxi service for the three down-Island towns this summer.

The Tisbury select board on Tuesday unanimously approved a harbor use permit for Falmouth Water Transportation Inc., which shares ownership with Falmouth Marine & Yachting Center and Vineyard Haven Marina.

The proposal still needs approval in Edgartown and Oak Bluffs, Falmouth Marine representative Misha Strumwasser told the Gazette Wednesday morning.

In Edgartown, the company wants to use Memorial Wharf, where its Pied Piper and Sandpiper ferries tie up.

Oak Bluffs has declined the use of its town bulkhead due to the need for jetty work, Mr. Strumwasser said.

“We’re investigating private dockage options,” he said.

Ticket prices for the water taxi service would be $15 per segment, Mr. Strumwasser said. If no dockage is found in Oak Bluffs for the season, he said, the fare will likely remain the same for a trip between Vineyard Haven and Edgartown.

The 38-passenger vessel, a twin-engine Chesapeake 46 built in 2006 and licensed by the Coast Guard for 2021, will berth and pump its waste tanks at the Falmouth marina, Mr. Strumwasser said.

Passengers of legal drinking age will be allowed to buy one drink of beer or wine per trip, he said.

“We’re not trying to run an alcohol cruise, just a water taxi,” Mr. Strumwasser said.

Tisbury select board members praised the proposal as a way to reduce cab and rideshare traffic on down-Island roads.

In other business Tuesday, the board approved the transfer of the Mad Martha’s Ice Cream eatery license to Brooke Katzen, who also owns Little House Café, Island Cove mini-golf and a taco truck.
