Although cycloidal propulsion is well known and has been widely accepted in European service for many years, its applications in the United States are relatively rare. The reasons for selecting this unique propulsion concept for the two new ferries now under construction for Manhattan-Staten Island service are described in this paper, as well as the design and construction problems encountered.

This paper presents the state of the practice of the use of cable barrier systems in the United States. A literature review was conducted to identify the types of cable barriers systems being used. The scope of this review included benefits of using cable barriers, available guidelines, policies or procedures related to barrier placement, and issues related to the maintenance and in-service performance of the cable barriers. A comprehensive survey was conducted to identify experiences, practices, and design and construction standards for the use of cable barrier systems. To improve survey quality, survey participants were people identified as managing the cable barrier systems firsthand. The participants were therefore likely to be most knowledgeable about the design and construction, maintenance, and overall experience of cable barrier usage. Concluding remarks about the state of the practice of cable barriers, along with areas of further research, are presented.

The design and construction of light hulls and floats suitable for flying boats and seaplanes is a very highly specialised branch of shipbuilding. This being the case, all matters pertaining to same Should be in the hands of naval architects. At a recent lecture before this Society, Commander Hunsaker, of the United States Navy, stated that British aircraft designers followed the naval architect's methods more than in any other country; he thought this was natural as he gave us the credit of being the first maritime power of the world. This may be perfectly true with regard to airships, but I cannot endorse his opinion that the majority of flying boats built in this country show the impress of the trained hand of a naval architect. I do not imply that the American boats are superior to ours, as for instance, a large American boat with twin engines built in the United States, which we used for the North Sea patrol, was by no means typical of good boat-building ; there were no less than four consecutive planks butted—not even scarfed—on the same timber, which had a siding of 5/8in., the line of butts being in line with the step where the boat was naturally weakest.

Architectural engineering, also known as building engineering, is the application of engineering principles and technology to building design and construction. Definitions of an architectural engineer may refer to an engineer in the structural, mechanical, electrical, construction or other engineering fields of building design and construction; a licensed engineering professional in parts of the United States; in informal contexts, and formally in some places, a professional synonymous with or similar to an architect. Structural engineering involves the analysis and design of physical objects (buildings, bridges, equipment supports, towers and walls). Those concentrating on buildings are responsible for the structural performance of a large part of the built environment and are, sometimes, informally referred to as “building engineers”.

The purpose of this paper is to present a brief outline of the general engineering procedure for the siting and design of jetties and the methods of constructing such structures. After a general presentation of the formulae proposed by various engineers to determine the size and weight of individual pieces of stone or other material which should be used under various wave heights, this paper will be devoted principally to the construction of rubble stone jetties. This is the type principally used on the Pacific Coast of the United States.
