Preface
The Gold Medal Awards 1997 is published by the Council o f the West Europe-an Confederation of Maritime Technology Societies ( W E M T ) in order to show the best paper produced by a member of each society participating in W E M T . However, because of the short preparation time not all the members o f W E M T could participate this time.
A publication in English opens up these papers to all the members of the rele-vant societies because otherwise they would have been published in the nation-al language only.
Moreover, such a publication i f selectively distributed, makes the ability o f the members of the societies concerned better known to a wider public with an interest in maritime technology.
Improved knowledge of as well as more interest in the prospects o f maritime technology in a wider public might support het present position of naval archi-tects and marine engineers, actually the brainpower in maritime developments. W i t h that support and together with other professions needed to be engaged in maritime industry the present situation with respect to the maritime market in Europe and abroad could be improved again.
Competition, whether fair or unfair, will be a fact of Hve in this worid and to beat the competition all organisations engaged in the maritime industry have to set all sails. So are the societies o f naval architects and/or marine engineers. 'Knowledge is power' is an old saying but still in force today and that we have to develop to the limits of our ability by research and development. Every opportunity to improve our knowledge should be grabbed by participation in either national or European research directed at application in the maritime industry.
However, that only will not be sufficient because knowledge and experience should also be brought forward with authority at all levels o f concern i n socie-ty. I t is to each one of us to support that task as well.
Whenever, the publication o f Gold Medal Awards can contribute to the aims as described above, i t will be worth the effort.
