Technical Papers (See table for time and place.)

Paper No. 1. "An Interactive

Computer-Aided Design Synthesis

Program for Recreational Power- boats" by D.E. Calkins.

SYNOPSIS—A computer pro- gram based on the design spiral concept has been developed for recreational powerboat design synthesis. The program combines conversational input with graphi- cal output, which allows the de- signer to communicate with the program in an interactive mode.

The program is based on 10 design and analysis technology modules, including configuration initializa- tion, hull architecture, mass prop- erties, hydrostatics, hydrody- namics, propulsion, performance, dynamic stability and response, structural design and operating economics.

Paper No. 2. "Design and Con- struction of a 25-M High-Speed

Aluminum Motor Yacht" by Pe- tros A. Lalangas and Panayiotis

L. Yannoulis.

SYNOPSIS—This paper pre- sents the design, construction and performance of a 25-m (82-foot), 32-knot, all-aluminum, luxury motor yacht. Model resistance and seakeeping data are given and compared with other efficient planing hull forms. The design of bottom structure, details on outfit- ting materials and weights, and noise abatement treatments are also discussed. Actual trial results and noise measurements are shown and compared with those of other planing craft.

Paper No. 3. "Revival of the

Flettner Rotor—Beneficial or Not for Merchant Vessels, Fishing

Boats and Recreational Craft" by

Ake Williams and Hans

Liljenberg.

SYNOPSIS—Experiments have been carried out at the Swedish

Maritime Research Centre (SSPA) aiming at rotor-powered merchant vessels, fishing boats and recrea- tional craft. Wind tunnel tests were performed to compare rotor and sail propulsion of a coaster of 950 tons deadweight. Complemen- tary "half-scale" tests at sea were carried out by use of a 6-m (20- foot) rotor-equipped test boat.

Paper No. 4. "Ultimate Strength of Ship Structures" by Yung-

Kuang Chen, Lembit M. Kutt,

Christopher M. Piaszczk and

Maciej P. Bieniek.

SYNOPSIS—Described in this paper is a method of analysis of the ultimate strength, as well as the total response, of ship struc- tures subjected to static or dy- namic loads. The analysis takes into account elasto-plastic proper- ties of the material, geometrically nonlinear behavior of the ele- ments and their buckling and post- buckling strength. The finite ele- ment based approach is applicable to individual structural compo- nents of a ship and to the hull gir- der as a whole. Selected applica- tions to typical ship structural problems are presented.

Paper No. 5. "The Jones Act: For- eign-Built Vessels and the Domes- tic Shipping Industry" by Warren

G. Leback and John W. Mc-

Connell Jr.

SYNOPSIS—Section 27 of the

Jones Act prohibits the transpor- ilaval 56 Maritime Reporter/Engineering News
