The ferry Islander of the Massachusetts Steamship Lines will make her shake-down cruise on Sunday and begin regular operation Monday, April 15, with four round trips daily between Woods Hole and Vineyard Haven, according to the schedule released today and announced by the line’s president, Paul E. Thurlow.

The ferry is the former Hackensack, used on the run across the Hudson between New York city and New Jersey. She can carry fifty automobiles and seat 500 passengers in service between Woods Hole and Vineyard Haven. Her scheduled time is one hour form slip to slip.

The good ship Chappy, huge freight scow which will this summer transport freight and automobiles over to Chappaquiddick Point and back, was the cynosure of all eyes Sunday, when she steamed all over the harbor. With Engineers Joe Costa and Jesse Jeffers coaxing the automobile engine turning the propeller, Capt. Tony Bettencourt walking the bridge, Joe Brown and Oscar at the tiller ropes, swinging the craft around in her own length, the scow made triumphant progress, loaded to the ribands with free passengers and accompanied by a great deal of assorted and uncalled for advice.

Steamer Nantucket was still fast in the sand of Sturgeon Flats this morning, with the prospect that more powerful towing equipment or the aid of a dredger will be needed to get her clear. Attempts were made to float her at high tide last night, and the working vessels were heard tooting again this morning in the thick fog which surrounded all the craft and made them invisible from the shore.
