Influence Analysis of Deck Equipment Positioning on Performances in Sailing

Headnote

Abstract

Authors in this paper presented the analysis regarding influence of deck equipment positioning and trimming, which is directly connected with sails, on sailing yacht performance in sailing. The analysis is performed by on-field measuring during sailing using specialized equipment based on RaceQs application and GPS support. The analysis is related to light wind conditions without significant waves, then to moderate wind and waves and finally to storm wind and high waves. Data collecting was performed during 30 hours of measuring and monitoring where the relevant equipment was continuously repositioned and trimmed aiming to reach more boat speed for different sailing angles. The results are processed and presented. The research was enabled with help and support of Bavaria Yachts d.o.o. Further analysis is suggested for different wind conditions and sea states.

Analiza utjecaja razmjestaja palubne opreme jedrilice na performanse kod jedrenja

Sazetak

Autori su u ovom radu izvrsili analizu utjecaja razmjestaja i prilagodavanja palubne opreme, a koja se nalazi u direktnoj vezi sa jedriljem, na performanse jedrilice kod jedrenja. Analiza je izvrsena mjerenjima na terenu, u plovidbi pod jedrima a koristenjem specijalizirane opreme temeljene na RaceQs aplikaciji uz GPS podrsku. Analiza se odnosi na dio mjerenja izvrsen u uvjetima laganoga vjeta bez znacajnih valova na moru, zatim pri vjetru srednje jakosti i umjereno valovitom moru i pri vjetru s olujnim udarima i valovitom moru. Prikupljanje podataka izvrseno je kroz 30 sati mjerenja i monitoringa unutar kojih se razmjestaj i prilagodavanje navedene opreme kontinuirano mijenjalo s ciljem postizanja vece bezine kod razlicitih kuteva jedrenja. Rezultati su obradeni i prikazani. Mjerenja su omogucena uz pomoc i suradnju s Bavaria Yachts d.o.o. Predviden je i nastavak analize za razlicite uvjete vjetra i stanja mora.

1.Introduction

An improvement in yacht design during last year's resulted in significantly enhanced performance of sailing vessels. However, growing competitiveness among designers has increased the demand for detailed experimental and computational research to better understand the behaviour of racing yachts and optimise their design and exploitation. Moreover, the operational complexity and performance requirements of modern racing yachts require the use of advanced applications [1].

Some applications are used for optimal...
