'Still Isn't Clear' What Caused Hyannis Ferry Crash, Steamship Authority GM Says

An investigation is underway to try figure out what happened Friday night when a ferry from Nantucket crashed into a jetty in Hyannis Harbor — sending 15 of the 57 people on board to the hospital. Several people on board had to be rescued by helicopter.

The high-speed ferry was negotiating bad weather, winds and choppy seas as it approached Cape Cod — which the Steamship Authority believes may have factored into the crash.

Steamship Authority General Manager Wayne Lamson joined WBUR's Weekend Edition Sunday to discuss the investigation.
