Andamå1gt_med_uppﬁinningen år att åstadkomma ett segel som är lika effektivt som nämnda vingprofilsegel och som dessutom fungerar lika bra for babords som for styrbords halsar. For att uppnå basta kryssformåga krävs också att vandningarna skall vara minst lika snabba och lätthanterliga som på en marconirigg.The spirit of the project is to achieve a sail that is as effective as the said wing profile sail and that also works as well for port as for starboard necks. In order to achieve the best cruising ability, it is also required that the irrigations must be at least as fast and easy to handle as on a marconi rig.

Metoden: Om en vingprofilformad mast med segel vänds uppochned vid varje stagvandning så skulle det teoretiskt gå att förena nämnda krav for optimal kryssformåga, men 1 praktiken blir det tämligen problematiskt. Md ett speciellt utformat råsegel går det dock. utfärandet: Genom att fasta seglet på en rå och hänga upp denna rå i sin mittpunkt i toppen av en kort mast(ca halva rålangden). så går det att vända seglet uppochned vid stagvandning. Hanovreringen av rån sker m h a en brass från vardera rånocken ner till båtens resp sida.The method: If a wing profile-shaped mast with a sail is turned upside down at each stay watering, it would theoretically be possible to combine the said requirements for optimal cruising ability, but in practice it becomes rather problematic. However, it is possible with a specially designed raw sail. the issue: By attaching the sail to a raw and hanging this raw in its center point at the top of a short mast (about half the raw length). then it is possible to turn the sail upside down when bracing. The maneuvering of the robbery takes place with a brass from each robbery ridge down to the respective side of the boat.

Seglet skotas (som sig brukas) akterut.The sail is pushed (as it is used) aft.

Observera att rån under segling inte år horisontell som på en råseglare, utan står närmast vertikalt. Den bör dessutom ha vingprofilformat tvarsnitt for att undvika virvelforluster och kan då tillåtas att ha stort tvärsnitt och kan göras styv.Note that robbery during sailing is not horizontal as on a raw sailor, but is almost vertical. It should also have a wing profile shaped cross section to avoid vortex losses and can then be allowed to have a large cross section and can be made rigid.

Inne in råns profil kan man också med fördel placera en rullfockanordning och låta seglet komma ut i en spalt i vingprofilens bakkant. Pâ detta sätt kan segelarean lätt anpassas till vindstyrkan.Inside the profile of the wreath, it is also advantageous to place a roller jib device and let the sail come out in a gap in the rear edge of the wing profile. In this way, the sailing area can be easily adapted to the wind strength.

Iånra_:s9linﬂaa:fa:anhatar Draksegelriggen visade sig vara snabb och lätthanterlig. Att brassa om rån i stagvändning gick ungefär lika snabbt som att skota om en fock på en “vanlig båt”.Iånra_: s9lin ﬂ aa: fa: anhatar The Dragon Sailing rig proved to be fast and easy to handle. Brass robbery in turn-turning went about as fast as shooting a jib on a "regular boat".

Man kan också luta seglet mot lovart på samma sätt som en vindsurfare och få en lyftkraft som minskar båtens krängning. Detta kan utnyttjas till att få båten att tåla större segelarea.You can also tilt the sail towards the wind in the same way as a windsurfer and get a lifting force that reduces the boat's heeling. This can be used to make the boat withstand a larger sailing area.

Hilda: Eial: Schematisk bild av draksegelriggad båt seglande för styrbords halsar. Brassarna år inte utritade, men babords brass år sträckt rakt ner till babords reling och styrbords brass är slak. Seglet ligger utanför babords vant och lutar in över båten.Hilda: Eial: Schematic image of a dragon sailing rigged boat sailing for starboard necks. The brass years are not drawn, but the port brass year stretched straight down to the port railing and starboard brass is slack. The sail is outside the port habit and tilts over the boat.

Eig2; Schematisk bild av en draksegelriggad båt sedd uppifrån när den är mitt i en stagvändning och håller på att brassa om rån. Rån hänger ett ögonblick horisontellt uppe i masttoppen och seglet blåser ut akterut och ser ut som en drake. 2191: Schematiskt tvärsnitt av en.vingprofilformad rå med rullanordning (av typ “rullfock“) inne i profilen.Eig2; Schematic image of a dragon sail rigged boat seen from above when it is in the middle of a turnaround and is about to burst into robbery. Robbery hangs for a moment horizontally up in the top of the mast and the sail blows out aft and looks like a dragon. 2191: Schematic cross-section of a wing profile-shaped raw with rolling device (of the type "rolling jib") inside the profile.

Claims

1. .l-'x KU 01 CD V) 04 _: Eitentkxal li A boat rig with sails, mast and raw, which is characterized in that the rod is movably suspended at its center on the aft side of the mast so that its outer ends can be alternately pulled down close the sides of the boat and that the sail is turned so that the part that was up before the turn is turned downwards after the turn and that the sail can blow out freely aft with wreaths horizontally and that the wreath cross section is wing profile shaped so that wafers together with the sail form a uniform wing profile against which the wind enters on the same side both before and after the boat's turn of the stay and that the robbery is the sail's only supporting profile and thus allows completely laminar air flow. Zl Device according to claim 1, characterized in that the wafer contains a rolling device for reducing the sail surface, where the sail is rolled up and comes out of a gap in the wafer.
