5 1 I. INTRODUCTION Throughout the 1970's and into the 80's, increasingly severe warnings were issued by leading spokesmen of the fisheries about the threat that the modest supply of new vessels for the Danish fishing fleet constitutes for the future competitiveness of the Danish fisheries. The longterm position of the Danish fisheries as a technological leader in coastal fisheries is, in spite of many technical inventions, facing a risk of being lost, and professional circles are increasingly of the opinion that Denmark no longer is the nation with the modern, well-equipped fishing fleet, as it has been replaced by countries such as Scotland, the Netherlands, Norway, and France. In 1983 and 1984, the fishing vessel supply experienced some boom, but in 1985 everything declined again due to the very strict restrictions on new construction. In the longer term, the decline in the production apparatus of the fishing industry constitutes a threat for the whole industry. Therefore, the Institute of Fisheries Technology decided in fall 1981 to invite representatives from the Laboratory of Ship Technology, the Jutland Technological Institute, the Experimental Laboratory of the Ministry of Fisheries, the Danish Fisheries and Marine Research Institute, Aalborg University Centre, Nordsocentret (North Sea Museum), the Institute of Fisheries Technology, and technical and economic advisory bodies of fisheries organisations to discuss the possibility that these institutions jointly establish a Danish vessel development project with a view to producing a new generation of vessels for the Danish fishing fleet. During the discussions, all institutions expressed both their interest in the project and their favorable attitude towards contributing to a fishing vessel project. It was agreed that the work be started with a preliminary project that would deal with the existing fleet structure and vessel lay-out within the Danish fisheries, and outline, on the basis of the material collected, those trends in boat-building that will characterize both Danish and foreign fisheries in the future. The plan was to establish jointly a Danish vessel development project based on the preliminary results, with an aim to produce a new generation of vessels for the Danish fishing fleet. The first part of the preliminary project was concluded with the report "Fleet structure and vessel lay-out in the Danishfisheries" by Henrik Flintegaard. The material assembled was inventoried, and a survey of it was published, titled "Survey of fishing vessel literature in the Danish Institute of Fisheries Technology" by Gunnar Petersen. The present report will focus on issues indicating future trends. This report concludes the preliminary project and attempts to point out details requiring further research in the form of new projects. The report has been compiled by Kent Nielsen, Laboratory of Ship Technology, who worked for the Institute of Fisheries Technology from to

8 I. INDLEDNING Op igennem halvfjerserne og ind i firserne har der med jœvne mellemrum lydt stadig alvorligere advarsler fra fiskeriets ledende talsmend om, at den beskedne tilgang af nybyggede fartojer til den danske fiskerflàde indebœrer en trussel for- danskfiskeri's fremtidige konkurreneeevne. Dansk fiskeris mangeàrige position scm teknclogiforer i det kystnœre fiskeri er her igennem, trods mange tekniske nyskabelser, kommet i fare for at gà tabt, og den opfattelse breder sig blandt fagfolk, at det ikke lœngere er Danmark, man skal soge tu, hvis man vil se en -moderne, veludrustet fiskerflàde, men derimod lande som Skotland, Holland, Norge og Frankrig. I àrene 83 og 84 var der nogen opblomstring i tilgangen af fiskefartojer. I 1985 gik det hele i stà igen pà grund ai meget skrappe restriktioner for nybyggeriet. Nedslidningen af fiskerierhvervets produktionsapparat og de fà nybygninger udgor pà lœngere sigt en trussel for fiskerierhvervet. Pà baggrund af ovenstàende tog Fiskeriteknologisk Institut i efteràret 1981 initiativ tu l at sammenkalde representanter for Skibsteknisk Laboratorium, Jysk Teknologisk Institut, Fiskeriministeriets Forsogslaboratorium, Danmarks Fiskeri- og Havundersogelser, Aalborg Universitetseenter, Nordsoeentret (Nordsomuseet), Fiskeriteknologisk Institut og fiskeriorganisationernes tekniske- og okonomiske konsulenter for at drofte muligheden for, at de nœvnte institutioner, i fœllesskab etablerer et dansk fartojsudviklingsprojekt med sigte pà at frembringe en ny "generation" fartojer til den danske fiskerflàde. I droftelserne gay samtlige institutioner udtryk for bàde interesse for og velvilje tu l at medvirke i et fartojsprojektsamarbejde. Man blev enige om at starte arbejdet med et forprojekt, som skulle belyse den eksisterende flàdestruktur og fartojsindretning i dansk fiskeri samt pà grundlag af indsamlet materiale uddrage de tendenser og linier i fartojsbyggeriet, som i sœrlig grad pegede fremover i dansk sàvel som i udenlandsk fiskeri.

9 - 2 - Pà grundlag af forprojektet var det sà tanken at soge bevilling tu l i fmllesskab at etablere et dansk fartojsudviklingsprojekt med sigte pà at frembringe en ny "generation" fartojer tu l den danske fiskerflàde. FOrste del af forprojektet blev afsluttet med rapporten "Flàdestruktur og fartojsindretning i dansk fiskeri", ved Henrik Flintegaard. Det indsamlede materiale blev registreret, og en oversigt over materialet blev samlet i rapporten "Oversigt over fiskefartojslitteratur pà.dansk Fiskeriteknologisk Institut" ved Gunnar Petersen. Nœrvmrende rapport vil herefter soge at trmkke de ting frem, som i smrlig grad péger fremover. Denne rapport er hermed afslutningen pà forprojektet og vil i konklusionen soge at trmkke nogle ting frem, som kunne trmnge tu l ydeligere undersogelser i nye projekter. Rapporten er udarbejdet af skibsingenior Kent Nielsen, Skibsteknisk Laboratorium, som i perioden 1/4-31/10-85 bar vœret tilknyttet Dansk Fiskeriteknologisk Institut.
