Σύνοψη

The aim of this project is to study and design a range of
universal yacht rudders, such that the rudders can be
stocked for sale.
In order to perform an efficient study, one should take
into consideration a lot of factors which could be of great
importance in the success of the study.
One of the most basic things is to determine the number of engines the yacht will dispose and, consequently, whether the rudder, (or rudders), is placed directly behind the engine or in a different way. Furthermore, one should
require the velocity of the boat for it is a fundamental
data for the later-to-be-calculated figures. Other factors
should be considered as well, such as span, chord, etc.
These shall be considered later on.
Due to the fact that there is no way by means of a formula, to evaluate the area or the shape of a rudder, this study will consider these as used normally in yachts of the same purpose and capacity. That is, the study will be based on already designed rudders for a similar purpose as in this case. For example, the dimensions of the rudders used in 15m length yachts, vary as following:
Span: 70, 80cmi
Chord: 30, 40, 50, 60cm.
Therefore, the designs will be based on these dimensions.
Another basic factor to be considered, is that of safety.
This will be initially based on the regulations for the
classification of yachts and small crafts, as registered by
Lloyds of England. Published every year in July, the
Register contains the names, classes and general
information concerning the ships classed by LLOYDS REGISTER
of shipping. Finally, during the design process,
compatibility between certain components (e.g. stock,
bearings, etc) should be considered in order to enable the
reduction of the final cost.
