Lani sam od jedne charter tvrtke kupio potpuno opremljenu 12-metarsku jedrilicu u vrlo dobrom stanju. Isprobao sam svu opremu i sve sisteme osim olujnog ili, kako ga još zovu, zavlačnog sidra.

Uredno je složeno i vidim da nikad nije korišteno, a budući da je jedrilica sada preregistrirana za osobne potrebe i ono više nije na popisu obavezne opreme, razmišljam o njegovoj prodaji. Ipak, zadržao bih ga ako ima ikakvu svrhu. Zanima me vaše mišljenje.

Marko M., Crikvenica

Sama činjenica da taj dio opreme postoji podrazumijeva i da ima nekakvu svrhu. Hoće li vam biti od koristi, ovisi i o načinu na koji koristite svoje plovilo. Ako plovite od marine do marine, i to uglavnom po lijepom vremenu, kao većina nautičara u charteru, zavlačno sidro vam i nije od nekakve koristi.

Kada plovilo na moru ostane bez pogona, ono se prema vjetru i valu uvijek okrene u najnepovoljniji položaj, bokom. U ekstremnim situacijama to može biti i opasno, a i bilo kakav pokušaj otklanjanja kvara s velikim bočnim valjanjem gotovo je nemoguć.

Kako bi se to izbjeglo, potrebno je pramac okrenuti u vjetar. Bez ikakvog pogona to je nemoguće, a zavlačno sidro u prvom redu služi upravo tome. Budući da znatno usporava kretanje plovila, ono će za isto vrijeme prevaliti i manji put, odnosno, produljiti vrijeme približavanja obali.

Stožac s rupom

Osim toga, budući da se njime smanjuje zanošenje, koristi se i kod nekih načina ribolova. Nadalje, u nekim uvjetima silina vjetra i vala manjim plovilima mogu ometati normalno kormilarenje, a puštanjem zavlačnog sidra po krmi ta se neugodnost može ublažiti.

Pomicanjem hvatišta, nekada čak tangunom, lantinom ili nekom drugom opremom improviziranom izvan krme, traži se najpovoljniji položaj.

Sidro je izrađeno od čvrste tkanine s više uzdužnih pojačanja i oblika krnjega stošca s odrezanim vrhom. Konop kojim je privezano treba otpustiti najmanje pet dužina plovila, a zatim ga se još popušta tako da se pozicija plovila u odnosu na sidro prilagodi amplitudi vala, čime se dosta smanji uranjanje i posrtanje pramca.

Čim se konop rastegne olujno, zavlačno ili kako ga još zovu plutajuće sidro počinje funkcionirati. Prednji široki otvor omogućava brzo punjenje morem, a konusni oblik sidra usporava protok. Glavnina vode ostaje u sidru, a stalni protok kroz stražnji manji otvor ne dozvoljava sidru da se skupi, pa zadržava oblik i stalno ostaje u funkciji. Veće sidro zadržava više vode i drži bolje, što je i normalno.

Olujnim sidrom pramac je stalno okrenut na vjetar i valove, a plovilo se lagano zanosi krmom. Ovim zanošenjem ispred pramca se stvara zatišje o koje se valovi djelomično lome, a veliki otpor sidra usporava naglo podizanje pramca na val, pa time i prolaskom vala njegovo uranjanje.

Pramac u vjetar

Oni koji plove na dužim relacijama rado ga imaju, jer je mogućnost neke nepredviđene situacije veća, a pomoć drugog plovila manje izvjesna. Budući da su udaljenosti između naših otoka i sigurnih skrovišta relativno male, malo tko među brodskom opremom posjeduje olujno sidro.

Ako ga i koristi, onda je to uglavnom za trajanja kratkotrajne nevere koja ga je zatekla u plovidbi. Ukloni se s plovnog puta, po pramcu pusti olujno sidro i pričeka da nevrijeme prođe.

Umjesto olujnog sidra može se upotrijebiti i dugački, debeli, neplutajući konop kao što je šperanca ili ga improvizirati od opreme koja vam je na raspolaganju, tende, tangun, mezomariner, stolnjak, malo sidro i bokobran, navlake,...

Cilj je nečim što ne pliva na površini nego pluta ispod površine stvoriti otpor dovoljan da pramac drži okrenut prema valu. Je li vam vrjednije imati ovakvu opremu u plovilu ili dobiti za njega nekoliko stotina kuna prodajom, to ipak procijenite sami.

Lani sam od jedne charter tvrtke kupio potpuno opremljenu 12-metarsku jedrilicu u vrlo dobrom stanju. Isprobao sam svu opremu i sve sisteme osim olujnog ili, kako ga još zovu, zavlačnog sidra.

Uredno je složeno i vidim da nikad nije korišteno, a budući da je jedrilica sada preregistrirana za osobne potrebe i ono više nije na popisu obavezne opreme, razmišljam o njegovoj prodaji. Ipak, zadržao bih ga ako ima ikakvu svrhu. Zanima me vaše mišljenje.

Sama činjenica da taj dio opreme postoji podrazumijeva i da ima nekakvu svrhu. Hoće li vam biti od koristi, ovisi i o načinu na koji koristite svoje plovilo. Ako plovite od marine do marine, i to uglavnom po lijepom vremenu, kao većina nautičara u charteru, zavlačno sidro vam i nije od nekakve koristi.

Kada plovilo na moru ostane bez pogona, ono se prema vjetru i valu uvijek okrene u najnepovoljniji položaj, bokom. U ekstremnim situacijama to može biti i opasno, a i bilo kakav pokušaj otklanjanja kvara s velikim bočnim valjanjem gotovo je nemoguć.

Kako bi se to izbjeglo, potrebno je pramac okrenuti u vjetar. Bez ikakvog pogona to je nemoguće, a zavlačno sidro u prvom redu služi upravo tome. Budući da znatno usporava kretanje plovila, ono će za isto vrijeme prevaliti i manji put, odnosno, produljiti vrijeme približavanja obali.

Stožac s rupom

Osim toga, budući da se njime smanjuje zanošenje, koristi se i kod nekih načina ribolova. Nadalje, u nekim uvjetima silina vjetra i vala manjim plovilima mogu ometati normalno kormilarenje, a puštanjem zavlačnog sidra po krmi ta se neugodnost može ublažiti.

Pomicanjem hvatišta, nekada čak tangunom, lantinom ili nekom drugom opremom improviziranom izvan krme, traži se najpovoljniji položaj.

Sidro je izrađeno od čvrste tkanine s više uzdužnih pojačanja i oblika krnjega stošca s odrezanim vrhom. Konop kojim je privezano treba otpustiti najmanje pet dužina plovila, a zatim ga se još popušta tako da se pozicija plovila u odnosu na sidro prilagodi amplitudi vala, čime se dosta smanji uranjanje i posrtanje pramca.

Čim se konop rastegne olujno, zavlačno ili kako ga još zovu plutajuće sidro počinje funkcionirati. Prednji široki otvor omogućava brzo punjenje morem, a konusni oblik sidra usporava protok. Glavnina vode ostaje u sidru, a stalni protok kroz stražnji manji otvor ne dozvoljava sidru da se skupi, pa zadržava oblik i stalno ostaje u funkciji. Veće sidro zadržava više vode i drži bolje, što je i normalno.

Olujnim sidrom pramac je stalno okrenut na vjetar i valove, a plovilo se lagano zanosi krmom. Ovim zanošenjem ispred pramca se stvara zatišje o koje se valovi djelomično lome, a veliki otpor sidra usporava naglo podizanje pramca na val, pa time i prolaskom vala njegovo uranjanje.

Pramac u vjetar

Oni koji plove na dužim relacijama rado ga imaju, jer je mogućnost neke nepredviđene situacije veća, a pomoć drugog plovila manje izvjesna. Budući da su udaljenosti između naših otoka i sigurnih skrovišta relativno male, malo tko među brodskom opremom posjeduje olujno sidro.

Ako ga i koristi, onda je to uglavnom za trajanja kratkotrajne nevere koja ga je zatekla u plovidbi. Ukloni se s plovnog puta, po pramcu pusti olujno sidro i pričeka da nevrijeme prođe.

Umjesto olujnog sidra može se upotrijebiti i dugački, debeli, neplutajući konop kao što je šperanca ili ga improvizirati od opreme koja vam je na raspolaganju, tende, tangun, mezomariner, stolnjak, malo sidro i bokobran, navlake,...

Cilj je nečim što ne pliva na površini nego pluta ispod površine stvoriti otpor dovoljan da pramac drži okrenut prema valu. Je li vam vrjednije imati ovakvu opremu u plovilu ili dobiti za njega nekoliko stotina kuna prodajom, to ipak procijenite sami.
