Annual Meeting — A Preview (continued) the design of such vessels. Applying environmental and operational loads and the analysis of structural response, the procedure has consid- erable potential for structural weight savings. Additionally, an ex- tensive reference list is included as well as comparisons to existing ves- sels and codes. 2:30 p.m.—"Prediction and

Measurement of the Performance of

Free-Flooding Ship Antirolling

Tanks," by William C. Webster,

John F. Dalzell and Roderick A.

Barr.

During the 1986-1987 CV-41 Mo- tions Improvement Program, pas- sive antirolling tanks were consid- ered for ship roll motions reduction.

Ship arrangements dictated the use of free-flooding type tanks with water "cross-over" external to the ship. This presentation addresses the primary problems faced in the engineering assessment of such tanks, the lack of quantitative per- formance data and of methods of predicting tank performance and tank impact on ship resistance.

Ladders J

A.L. Don now offers a new and greatly improved pilot ladder with a patented clamp- ing device for easy & quick step re- placement. .. even on board ship.

Additional features include a newly designed, non-skid surface... Steps are painted international safety or- ange ... Synthetic polypro-dacron suspension ropes with a white outer jacket and orange inner safety core... Steps & clamps made from Dupont® High Impact strength Surlyn HR Our new lad- ders are U.S.C.G. approved and meet or exceed all SOLAS regula- tions and IMO standards. A.L. Don

Pilot Ladders are available coast-to- coast. And. best of all, our competi- tion can't match our low prices.

Three models for minimal time ship weather routing are presented, for stationary, time-dependent (but known) and probabilistic weather conditions, respectively. These models allow for prohibited sailing regions (land or other constraints), intermediate destinations with time delays, and updated weather infom- ration (for the probabilistic case).

Mathematical techniques from the calculus of variations, dynamic pro- gramming and optimal control are used. 10:30 a.m.—"Performance

Analysis of a Small Racing Boat in

Combination Container and RO/RO

Ship," by Ronald F. Briggs,

Christopher T. Clement and

Peter A. Fisher.

Originally designed as a pure trailership, the Matsonia was recon- structed as a combination contain- er-RO/RO vessel to suit the West

Coast-Hawaii trade, entering ser- vice in late 1987. This presentation traces the economic analysis, design evolution, reconstruction system, equipment reactivation and early operational experience of the ship and discusses many of its unique features.
