Hears Paper On Final Design

Of The Golden Gate Ferries

Shown at the Northern California Section meeting in

San Francisco, left to right: Philip F. Spaulding, au- thor, Nickum & Spaulding, naval architects, Seattle,

Wash.; Joseph Busch, outgoing Section chairman;

Phillip Eisenberg, national Society president, Hydro- nautics Inc., Washington, D.C., and Robert Herbert, incoming Section chairman, naval architect.

An overflow crowd of members of the

Northern California Section of The Society of Naval Architects and Marine Engineers at the Engineers Club in San Francisco re- cently heard a presentation by Philip F.

Spaulding of Nickum & Spaulding Associ- ates, Inc., Seattle, Wash., on the "Considera- tions Affecting the Final Design of the Golden

Gate Ferries." Mr. Spaulding, the author, reviewed the detailed studies of traffic and growth patterns in the Bay Area, and pro- vided the audience a comprehensive picture of the practical as well as theoretical, eco- nomic and engineering considerations result- ing in the design as currently under con- struction.

Unique features that were discussed in detail were the increase in U.S. Coast Guard acceptance of aluminum in fireproof con- struction, and the gas turbine water jet pro- pulsion system. These unusual features were required to minimize weight due to the shal- low draft in some of the areas served.

Subsequent discussion brought out that the alternative of a Hovercraft was dis- missed due to the absence of sufficient U.S. development of the necessary technology.

It was explained that an unusual degree of passenger comfort was required in this de- sign due to the direct competition with free- way automobile transportation. It was indi- cated that this is the only effort ever made to compete directly for ferry passengers in this manner.

Discussors at the meeting were: Stan

Koleski, Golden Gate Bridge Authority; Zack

Reynolds, Merritt Ship Repair; Alan Wink- ley, naval architect; James Sweeney, Mare

Island Naval Shipyard; Marshall Silverthorn,

T.T. Lunde; James Brown, Matson Naviga- tion ; Bruce Bishop, Chevron, and Roger Pot- ash, Litton Industries.

Additionally featured at the meeting was an address by Phillip Eisenberg of Washing- ton, D.C., national Society president. He presented a certificate of appreciation to

Joseph Busch, outgoing Northern California

Section chairman.
