Introduction

(2) A number of programs can be combined to form a computer aided design system where the output from one program provides a direct input into others. Revisions of the database as the design develops can be used to up-date automatically the results of calculations carried out earlier. Thus changes in scantlings occasioned by the strength calculations can up-date displacement and stability estimates. The end result of the hull fairing process leads to a tape which can be supplied to the shipbuilder instead of the lines plan and table of offsets.

(3) More data is immediately available to the designer to assist in decision-making.

(4) Many more design options can be studied and compared and these can be at an earlier stage in design and in greater detail.

(5) Simulations can be produced of what the finished ship will look like, internally as well as externally. These can be used instead of mock-ups to assist in achieving efficient layouts. The colours and textures of different materials can be shown. An owner can effectively be taken for a walk through his ship before it leaves the drawing board (Thornton, 1992).

(6) In production the computer can help with routine matters like stock control. It can control cutting and welding machines ensuring greater accuracy of fit and facilitating more extensive pre-fabrication and reducing built-in stress levels.

(7) On board it can control machinery and monitor its performance to give early warning of incipient failure.

(8) It can help the command with decision-making. For instance, it can advise on loading sequences to eliminate the possibility of overloading the structure. It can assist warship captains when under enemy attack by suggesting the optimum actions to take in defence.

(9) Computer-based simulators can assist in training navigators, machinery controllers and so on.

It is hoped that these few paragraphs have shown that naval architecture can be interesting and rewarding. An example of the variety and interest to be found in the profession can be obtained by reading the memoirs of an eminent naval architect, Marshall Meek (2003). The various topics mentioned above are discussed in more detail in later chapters where the fundamental aspects of the subject are covered. The references given at the end of the book, arranged by chapter, indicate sources of further reading for following up specific topics. A more advanced general textbook, for instance by Rawson and Tupper (2001), can be consulted if desired. This has many more references, together with worked and set examples, to assist the interested reader. For comments on sources and references see Appendix A.

How To Have A Perfect Boating Experience

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
