Chatham Area’s Mary

Musgrove

The Mary Musgrove, a 67-ft T-

Class passenger ferry, is being built by Custom Steel Boats, Inc. for the

Chatham Area Transit Authority in

Savannah, Ga. It is scheduled to be delivered mid-September 2011.

The Mary Musgrove is powered by two John Deere 8.1 liter 6081

AFM75 M1 engines and propelled by two Schottel Z-Drives. The ves- sel will also be equipped with an 18- inch Wesmar hydraulic bow thruster and a single 46 kW

John Deere generator. The engines, gen- erator and four four-ton

Cruisairs will be cooled by

Fernstrum

Keelcoolers. It will accommodate 150 passengers for transportation to the

International Trade and

Convention Center located on

Hutchinson Island from downtown

Savannah. While the Mary

Musgrove is the third vessel to be built for the Chatham Area Transit

Authority, it is the first to be built by Custom Steel Boats, Inc. and designed by DeJong and Lebet. The vessel is being funded in part by federal stimulus dollars and in part by a grant from the U.S. DOT.

Incat Crowther announced a con- tract to design a 110-ft Catamaran

Ferry for operation in Florida. The vessel will be built by Gladding-

Hearn for Yankee Fleet. To be named

Yankee Freedom III, the vessel will replace Yankee Freedom II, designed and built by the same partnership in 1999. She will operate on the compa- ny’s daily run from Key West to Dry

Tortugas National Park and Fort

Jefferson. Yankee Freedom III will be the 37th ferry built by Gladding-

Hearn to Incat Crowther’s designs.

The vessel will feature an isolated superstructure, reducing the trans- mission of noise and vibration to the passenger spaces, as well as offering construction efficiency. The fully

ADA compliant main deck features 142 seats and four wheelchair spaces, all with tables. There is a large bar and shop aft, with an additional serv- ing counter. Aft of the bar are four toilets, one of which is wheelchair accessible. There are some exterior seats on the aft main deck, allowing passengers to enjoy the sunset on return journeys. The main deck cabin features forward doors with direct access to the foredeck, which is opti- mized for aquatic wildlife viewing.

The upper deck features 52 exterior seats. Inside, there are 56 seats, some with tables, and a small additional bar. Yankee Freedom III will be pow- ered by a pair of Caterpillar 3512C engines, which are Tier II emissions compliant. These engines each pro- duce 1,230 kW at 1,800 rpm. The vessel will have a service speed of 28 knots.
