The annual joint meeting of the New York

Metropolitan Section of The Society of Naval

Architects and Marine Engineers and The So- ciety of Marine Port Engineers New York,

N.Y., Inc. was held on December 12, 1972, at the New York Times Building in New York

City.

After a social hour and buffet in the Execu- tive Dining Room, the technical session was held in the WQXR Auditorium, where a paper was presented entitled "Design and Economics of Integrated Tug-Barge Systems," by Robert

P. Giblon and Robert J. Tapscott of George G.

The paper discusses the reason for the cur- rent interest in integrated tug-barge and out-

Radiomarine Floating Exhibit

Embarks On Year-Long Tour

The converted 43-foot houseboat is outfitted with more than $50,000 worth of new radar systems and other communications and navigation aids made at Radio- marine's Red Bank, N.J. plant.

An unusual floating demonstration labora- tory has been outfitted by Radiomarine Cor- poration to show off its new line of radar and communications systems.

The vessel, a converted 43-foot houseboat, recently departed Red Bank, N.J., on a year- long tour of some 20 seaports along the At- lantic and Gulf Coasts.

During the port visits, scores of shipowners and captains and other marine industry figures will be invited aboard to inspect the new equip- ment and observe it in actual operation.

Radiomarine technicians have installed aboard the vessel more than $50,000 worth of new radar systems, communications units and lines their history leading up to current de- velopments in such designs, citing specific ex- amples. Propulsion plants are discussed and single-screw and twin-screw propulsion sys- tems are compared.

The paper discusses a number of applica- tions, both commercial and military, for which integrated tug-barge systems would be par- ticularly suitable because of the flexibility of- fered by the detachable, interchangeable pow- er plant (tug), and the relative lower first cost and operating cost as compared to a ship; the relative economics of tug-

Richard D. Durrett, Radiomarine sales man- ager, will be in command of the demonstration ship, and will be assisted by company elec- tronic specialists and by regional sales and service personnel-

C. Webber Parrish, Radiomarine vice presi- dent and general manager, will also be present at a number of the port visits. Mr. Parrish himself conceived the idea for the novel dem- onstration and tour. "We believed the most dramatic and prac- tical way to present our new radar units and other marine equipment was to take it out and show it in action," Mr. Parrish explained.

He said that prospective customers at each port would be taken on short cruises so they could inspect the equipment and try it out un- der actual operating conditions.

New Radiomarine products on display aboard the floating exhibit are a 16-inch radar system for the world's largest oceangoing vessels, a smaller radar unit suitable for tugs, fishing boats, river freighters and similar commercial vessels, several types of radio telephones, short wave, single sideband radio transceivers, auto- matic loran navigation equipment and hand- held two-way radios.
