The Impossible Dream is celebrating 10 years of docking on Martha’s Vineyard.

The fully accessible catamaran sails around the east coast, bringing people with disabilities out on the water. It is the only boat in the world that was purposefully built to be fully accessible, where all aspects of sailing can be done by any sailor in a wheelchair.

This summer, the boat has brought people from Camp Jabberwocky, Windemere Nursing and Rehabilitation Center and the Vineyard Independence Partnership out sailing.

On Tuesday morning, the team at Impossible Dream honored Menemsha harbormaster Ryan Rossi with a plaque, thanking him and the town for allowing them to dock there every summer for the last decade.

“We love coming here and we love serving the Martha’s Vineyard community,” said executive director and captain William Rey while presenting the plaque. “So [this is] just as a little token of our appreciation for everything that you have done. We wouldn’t be here if it wasn’t for the hospitality, because that’s why we keep coming back.”

Mr. Rossi said he is happy to carry on a tradition that predates his time as harbormaster and hopes it will continue for many years.

“The town has always allowed them the dock space free of charge because of what they do for the community,” he said. “I just think that their cause is something that really helps the community and it’s a pleasure to have them on the dock.”

The Vineyard’s connection to The Impossible Dream began with Charlie Shipway, who grew up sailing during summers on Menemsha Pond. Mr. Shipway went on to compete in the 1992 Summer Olympics in Barcelona before coming back to sail and race in Menemsha and live full-time on the Island.

When his long-time sailing partner Richard Bluestein suffered a stroke in the early 2010s, making his right side completely paralyzed, Mr. Shipway wanted to build a boat that would allow his friend to sail.

He was introduced to Shake-A-Leg Miami, an organization that provides sailing experiences for people with and without disabilities, and met Harry Horgan, co-founder of Shake-A-Leg Miami and The Impossible Dream. That began the relationship between The Impossible Dream and Martha’s Vineyard.

Mr. Shipway said he is grateful to Menemsha for continuing to welcome The Impossible Dream back to its waters.

“[Ryan’s] got such a great crew, and he’s so helpful in making this all happen,” Mr. Shipway said.
