World's Largest Catamaran Ferry In Service

Rokko Maru, 2,700-gt catamaran ferry, making crossing from Kobe to Takamatsu, Japan.

The Rokko Maru, a 2,700 gross ton catamaran ferry, the world's largest, built by Nippon Kokan, has entered service between Kobe and Takamatsu on Japan's Inland

Sea.

Hiroo Ikematsu, NKK's New

York naval architect, said the new vessel, built for Kansai

Steamship Co., Ltd., is about five times larger than most catamarans operating in Japan, which aver- age 500 gross tons.

The Rokko Maru can accommo- date the equivalent of 42 heavy trucks, 10 light trucks, 50 auto- mobiles, and 580 passengers. Two areas on the main deck and one on the passenger deck collectively provide 2,820 square yards for ve- hicle loading. The main deck has an area of 1,830 square yards, equivalent to an athletic field with a 660-foot track. Facilities include a deluxe observation lounge above the passenger deck and a spacious economy section with snack coun- ter service.

Principal characteristics of. the

Rokko Maru are as follows: overall length,274 feet 1-jHs inches; overall length bpp, 255 feet 10-% inches; breadth molded, 82 feet %

Talbot Appointed

Staff Engineer

For Kelvin Hughes

Peter M. Talbot has been ap- pointed staff engineer for Kelvin

Hughes Division, Smiths Indus- tries, Inc., a British-based marine electronics firm with North Amer- ican operations headquartered at

Woburn, Mass.

Mr. Talbot will be responsible for systems engineering and new product development for the com- pany's North American operations, according to G.M. Benas, Division vice-president.

Before joining Kelvin Hughes,

Mr. Talbot was a senior engineer with the Raytheon Company; and before that he was with National

Radio Company.

A graduate of Tufts University with a B.S.E.E. degree, Mr. Talbot also served four years as a first inch; single hull breadth molded, 22 feet 11-^ inches; depth molded, 26 feet 3 inches; draft molded, 15 feet 4*4 inches.

The distance between Kobe, a major port city on Honshu Is- land, and Takamatsu on Shikoku

Island, is 70 miles. The new ferry, with a cruising speed of 19 knots, is the fastest ship now traveling between the two islands. She is powered by two Daihatsu 8DSM- 26 diesel engines, one in each hull, which develop 5,760 hp at 695/ 185.5 rpm.

Mr. Ikematsu said the catamaran design offers several advantages compared with conventional single hull ferries. Among these are ex- ceptionally spacious deck space due to the wide platform afforded by the twin hull design; excellent maneuverability because of the shallow draft and the wide separa- tion between the two engines; su- perior stability because the twin hull design has less wave resis- tance than conventional vessels; high service-speed compared with main engine horsepower and gross tonnage; and ease of loading and unloading vehicles afforded by the inclined bow ramp. lieutenant in the United States Air

Force.

Kelvin Hughes is a leading manufacturer of radar, loran, and marine communications equipment for commercial and pleasure ves- sels, and has sales and service facilities located in key ports throughout North America and around the world.
