Kana zvasvika kune cheni dzeanchor, vazhinji vedu tinotevera mitemo yekutanga yechigunwe, asi Christopher Smith anotenda kuti tinofanira kufunga nezvemhepo, masaisai uye mafambiro.
Zvibatiso zvakabatikana zviri pachena zvinoda kuti iwe ushandise maketani mashoma pane dzimwe nzira dzekudzikisa wiggly madenderedzwa, asi unoziva sei kuti hauzodhonza?
Anchoring chikamu chakakosha chezvombo zvevatyairi vechikepe - zvirinani kune avo vasingade kupotera pese panomira ngarava.
Nekudaro, kune yakakosha chikamu chevaraidzo yedu, zvingave zvakaoma kuwana ruzivo rwakavimbika pamusoro pezvakawanda zvemaitiro.
Muzviitiko zvakawanda, mutemo wakanakira wegunwe unodiwa unogona kushandiswa kuve nechokwadi chekuti wakasungirirwa zvakachengeteka mumamiriro mazhinji.
Mukureva kwayo, kuverengerwa kwemitemo ine simba haigone kutarisisa zvese zvikamu zveanchoring equations, asi zvinoshamisa kuti vanhu vazhinji vanopotsa mafungidziro akakosha nekuti zvinonetsa kuapinza mufomura yakapfava.
Wese munhu ane mazano ake ekuti mangani eanchor cheni ekushandisa.Iyo yakapfava-uye pamwe ndiyo yakajairika nzira-sei kurashira kure maketani ese akachengetwa mulocker?
Mukuita, izvi zvinowanzoreva kushandisa kureba kwakachengeteka kwepamusoro - chero anchorage ine matombo, shallows nezvimwe zvikepe zvakamiswa paunosvika, kana kazhinji mushure mekunge wasvika.
Saka, usati watsvaga zvimwe zvibatiso, unoziva sei zvakachengeteka?Sechinyakare, unoshandisa oscilloscope (yakawanda yemvura yakadzika) kuti uone kureba kweketani yeanchor yaunoda kushandisa.RYA inokurudzira huwandu hunosvika 4:1, vamwe vachiti unoda 7:1, asi inowanzoitika munzvimbo dzine vanhu vakawanda pa3:1.
Zvisinei, pfungwa yechinguvana inokuudza kuti munzvimbo umo shanduko dzakakosha dzinogona kuitika pasi pemamiriro akasiyana, mitemo yakadzikama yezvigunwe haina kukwana kutsanangura masimba makuru anoshanda muchikepe, anoti mhepo nemafungu emvura.
Kazhinji, mhepo ichava dambudziko guru, saka iwe unofanirwa kufunga nezve izvi, uye ziva uye ugadzirire huwandu hunotarisirwa hwemhepo.Panewo matambudziko;pane zvinyorwa zvishoma kana mabhuku ezvinyorwa pane anchors zvinogona kukuudza kuti ungafunga sei simba remhepo paunenge uchiisa anchor.
Nokudaro, ndakauya negwaro rakanyanya nyore kuti ndipe mutemo wekuverenga chigunwe (pamusoro), iyo inotarisawo mhepo nemafungu.
Kana iwe usingaone chero chinhu chakakura kupfuura pamusoro pe "Force 4" (16 knots), uye simbisa yacht 10m mumvura isina kudzika, zvinoreva kuti kudzika kuri pasi pe8m, kunofanira kunge kuri 16m + 10m = 26m.Zvisinei, kana iwe uchifunga kuti 7 mhepo dzine simba (33 knots) dziri kuuya, edza kuisa cheni ye 33m + 10m = 43m.Mutemo wezvigunwe uyu unoshanda kunzvimbo zhinji dzeanchor pamahombekombe (apo mvura haina kudzika zvakanyanya), asi kune yakadzika ma anchor point (inenge 10-15m), cheni dzakawanda dziri kudiwa zviri pachena.
Mhinduro iri nyore: unongoda kushandisa 1.5 nguva yekumhanya kwemhepo kuti uwane mhedzisiro iri nani.
Tsika dzevabati vehove dzinogona kupetwa kuita chimiro chakati sandara kuti zvive nyore kurongedza uye dzinogona kugadzika pamatombo nesora, asi zvipikiri zvidiki zvinogona kudhonzerwa kune chero imwe pasi uye zvishandise sechibatiso chikuru.
Kana simba rekudhonza rikakura zvakakwana, CQR, Delta neKobra II anchor dzinogona kukweva, uye kana jecha riri jecha rakapfava kana kuti dhaka, rinogona kukwevera pasi pegungwa.Iyo dhizaini yakagadziridzwa kuti iwedzere iyo yakanyanya kubata simba.
Bhuruu chaiyo yave ichigadzirwa kwemakore mazhinji, uye makopi mazhinji akagadzirwa, kazhinji akagadzirwa negiredhi yakaderera, isina kusimba uye isina kusimba zvinhu.Chigadzirwa chechokwadi chinogona kugadziriswa kune zvinyoro kusvika pasi pepakati pepakati.Zvinonzi inogona kugadzikwa padombo, asi kumberi kwayo kureba kunonetsa kupinza sora.
Danforth, Britany, FOB, Fortress and Guardian anchors dzine nzvimbo yakakura yepasi nekuda kwehuremu hwadzo, uye inogona kunyatsogadziriswa pane zvakapfava uye zvepakati pasi.Pamazasi akaoma, sejecha raunganidzirwa uye shingles, anogona kutsvedza pasina kusimba, uye haadzoreki patsva kana masaisai kana mhepo yachinja kwainodhonza.
Ichi chikamu chinosanganisira Bügel, Manson Supreme, Rocna, Sarca uye Spade.Dhizaini yavo ndeyekuita kuti zvive nyore kumisikidza uye kuseta patsva kana masaisai achinja, uye kuve nekuchengetedza kwakanyanya.
Nzvimbo yekutanga yezviverengero izvi ndeyekupeta kwekatenari mumvura, iyo inotumira lateral simba kubva muchikepe kuenda kugungwa.Mabasa emasvomhu haanakidze, asi kune akajairwa anchoring mamiriro, kureba kwekatenari kune hukama hwemutsara nekumhanya kwemhepo, asi kutsetseka kunongowedzera neskweya mudzi wekudzika kweanchoring.
Kune zvibatiso zvisina kudzika (5-8m), mutsetse uri pedyo neyuniti: catenary urefu (m) = mhepo inomhanya (knot).Kana nzvimbo yeanchor yakadzika (15m), pakadzika 20m, mutsetse unokwira kusvika pa1.5 uye ku2.
Iyo square root factor ine hudzamu inoratidza zvakajeka kuti pfungwa yemhando yakashata.Semuenzaniso, kushandisa mhepo iripo kana inotarisirwa Nha.
Nhamba yemaketani anoshandiswa mumamiriro ezvinhu akadzikama anofanira kunge akasiyana nehuwandu hwemaketani anodiwa kana mhepo yakasimba
Sezvakataurwa naRod Heikell (Zhizha Yacht Monthly 2018): "Kanganwa iyo inowanzoitwa 3: 1 scope: zvishoma enda 5: 1.Kana iwe uine nzvimbo yekugezera, saka Zvimwe.”
Simba remhepo rinoenderanawo nechimiro chengarava (mhepo yakananga).Unogona kuyera nhamba yemacheni anosimudzwa pamhepo yakapihwa kumhanya (V) uye kudzika (D) uchishandisa inotevera formula: catenary = fV√D.
Yangu "yakadzika anchor" kuverenga kwakavakirwa pachikepe changu (10.4 m Jeanneau Espace, 10 mm cheni) uye kudzika kwe6 m.Tichifunga kuti saizi yeketani inowedzera zvichienderana nehukuru hwechikepe, kukosha kuchave kwakafanana kune mazhinji ekugadzira yachts.
Kutuhwina nekufamba kwemakore kuona mapoinzi eanchor mumvura inodziya yeMedithera yakandipwisa kuti iyo yakanakisa cheni kureba ndiyo catenary pamwe nekaputeni.
Kureba kwecheni yakavigwa mujecha kana madhaka zvakare kunoderedza zvakanyanya kushushikana pachibatiso.Saka fungidziro yangu yakanaka ndeye: yakazara cheni = katenari + kaputeni.
Zvinonzi kuti chibatiso chipinde mugungwa, cheni yacho inoda kurerekera kumusoro, kureva kuti, kureba kwayo kudiki pane mambure okubata nawo.Nekudaro, ndosaka isu tichishandisa mota kumashure mushure mekumisa-simudza kona yecheni uye kusundira anchor pasi.
Iyo anchor retention force haina kutariswa pano.Izvi zvakakosha uye zvinokurukurwa mune zvimwe zvakawanda zvinyorwa.
Simba rechipiri rinoshanda pachikepe ndiko kupikisa kwemafungu emvura.Zvinoshamisa kuti iwe unogona kuzviyera nyore iwe pachako.
Pazuva rine mhepo, mota yemagetsi inofamba zvishoma nezvishoma ichipinda mumhepo, inoderedza sipidhi, uye inowana sipidhi yeinjini inonyatsoenzanisa mhepo.Zvadaro, pazuva rakadzikama, teerera kumhanya kwechikepe kunobudiswa nekumhanya kwakafanana.
Pachikepe changu, iyo yakazara Force 4 mhepo inoda 1200 rpm kudzikamisa mhepo-pakadzikama 1200 rpm, pasi kumhanya i4.2 mapfundo.Nokudaro, 4.2 mafundo ekuyerera kwesimba achaenderana ne16 mafundo emhepo, uye 16m cheni inodiwa kuti ienzanise iyo, kureva, ketani ine ikozvino inenge 4m per knot.
Cheni dzeanchor dzinowanzo iswa danho remamita gumi, saka nzira inoshanda ndeyekutenderedza chigumisiro chekuverenga kusvika pa10m iri pedyo.
Kune zvese zvinyorwa nezve anchoring uye nhaurirano nezve chiyero, zvinoita sekunge kutariswa kushoma kunopiwa kune nzira yekubvumidza kusimba kwemhepo.
Ehe, kune zvimwe zvinyorwa zve geek nezve kureba kwekatenari, asi mashoma anoedza kuishandisa pakudzidzira chikepe.Ndinovimba kuti zvirinani iwe unogona kumutsa maitiro ako ekufunga kuti ungasarudza sei kureba kweanchor chain.
Dhinda uye shanduro dzedhijitari dziripo kuburikidza neMagazines Direct, kwaunogona kuwana zvekare zvibvumirano.
