In many cases of ships' waterplanes it is sufficiently accurate to use ten divisions with eleven ordinates but it is worth checking by eye whether the straight lines follow the actual curves reasonably accurately. Because warship hulls tend to have greater curvature they are usually represented by twenty divisions with twenty-one ordinates. To calculate the volume of a three dimensional shape the areas of its cross sectional areas at equally spaced intervals can be calculated as above. These areas can then be used as the new ordinates in a curve ofareas to obtain the volume.

Simpson's rules

The trapezoidal rule, using straight lines to replace the actual ship curves, has limitations as to the accuracy achieved. Many naval architectural calculations are carried out using what are known as Simpson's rules. In Simpson's rules the actual curve is represented by a mathematical equation of the form:

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.
