Imboni yezikebhe zezentengiselwano nezokungcebeleka emhlabeni wonke iyathuthuka kancane kancane, futhi izikebhe zejethi zithola ukuthandwa okukhulayo emhlabeni wonke. Sekungamashumi eminyaka, izikebhe ezijwayelekile ze-propeller ziphethe imakethe. Besekelwa amasu okukhiqiza avuthiwe kanye nezinzuzo zezindleko, banelisa ngokugcwele izimfuno eziyisisekelo zokubona indawo kanye nezimfuno zokugibela izikebhe ezizimele. Kodwa-ke, njengoba izimo zebhizinisi lamanzi zihlukahluka, izindinganiso zokuphepha zasolwandle ziyathuthuka, futhi izivakashi ziphishekela okuhlangenwe nakho kokugibela kwekhwalithi ephezulu, izithiyo ezikhona ezikebheni zophephela bendabuko ziye zagqama kakhulu. Ngokumelene nalokhu kwangemuva, ubuchwepheshe be-jet boat buye baqashelwa kabanzi yimboni yasolwandle yomhlaba wonke, iba inkomba yokuthuthukisa imikhumbi yesimanje yezentengiselwano.
Esikhathini esedlule, ukuvakasha okuningi kwamanzi kanye nokuthuthwa kwabagibeli kwakusebenza emanzini avulekile, ajulile futhi azolile, lapho izikebhe zejubane ezijwayelekile zazisebenza kahle kakhulu. Ibhizinisi lanamuhla lamanzi lihlanganisa izindawo ezihlukahlukene kakhulu, kuhlanganise namachibi angashoni phakathi nezwe, izindawo ezisogwini ezinamagagasi, kanye namanzi okuzijabulisa agcwele izithiyo. Lezi zimo ezintsha zidinga izikebhe ezinokusebenza okuqinile kokuphepha kanye nezimo ezingcono zemvelo.
Izikebhe zophephela bendabuko zibhekana nezithiyo ezivamile emanzini ayinkimbinkimbi. Ophephela abaveziwe kulula ukushaya izithiyo ezingaphansi kwamanzi noma bahlangane nokhula nezintambo zokudoba, okuholela ekuhlulekeni njalo kanye nezingozi zokuphepha. Ukuze kuxazululwe lezi zinkinga ezingokoqobo, imboni kancane kancane iyashintsha isuka ekuthengeni izindleko kuphela iye ezixazululweni ezigxile kusimo, okwenza ubuchwepheshe be-jet boat obushintshashintshayo budume kakhulu.
Izikebhe ze-jet zithola ukuthandwa kwemboni ikakhulukazi ngenxa yesimiso sazo esiyingqayizivele sokusebenza. Esikhundleni sama-propeller angaphandle, isikebhe sejethi sisebenzisa isistimu yejethi yamanzi yangaphakathi ukuze iqhube. Ngokufanayo nendlela amabhanoyi asebenza ngayo, injini yesikebhe ishayela iphampu esemkhunjini ukuze imunce amanzi futhi iwafafaze iwakhiphe ngesivinini esikhulu ukuze ikhiqize ukudonsa. Ngokulungisa isiqondiso sendiza yamanzi, abaqhubi bangakwazi ukuqondisa ngendlela eguquguqukayo futhi baqedele ukuqondisa okunembe emanzini.
Lo mklamo uxazulula ubuthakathaka obuyinhloko bokuqhutshwa kophephela ovamile. Ngezingxenye zejethi ezivaleke ngokugcwele, izikebhe zejethi zigwema ukulimala kophephela, ukubambeka kanye nezingozi eziphansi, zinciphisa kakhulu izinkinga zokulungisa kanye nezingozi zokuphepha. Ngaleso sikhathi, i-jet propulsion iletha ukusheshisa okusheshayo, ukuhamba ngomkhumbi okuzinzile okunesivinini esikhulu kanye nokuguquguquka okungcono kakhulu. Izikebhe ze-jet zingakwazi ukukhukhuleka, zishelele emaceleni futhi zijikeleze ngokukhululeka ngesivinini esiphezulu, ukunyakaza izikebhe zejubane ezijwayelekile ezingakwazi ukukufinyelela. Lokhu kwenza izikebhe zejethi zibe umphelelisi ofanele ezikebheni zejubane ezijwayelekile ezidinga kakhulu nezimo eziyinkimbinkimbi zamanzi.
Ukusimama kanye nokuthuthukiswa kwemboni yezokuvakasha emanzini emhlabeni wonke kusiguqule ngokuphelele isidingo esisodwa "sokuzulazula okuphephile" esikhathini esedlule. Izivakashi zesimanje ziphishekela ulwazi lwamanzi acwilisiwe, ajabulisayo futhi ahlukahlukene, kuyilapho abaqhubi bezohwebo benaka kakhulu ukuqina kwemishini, izindleko eziphansi zokunakekela kanye nezinzuzo zokusebenza zesikhathi eside. Ukuphindaphinda kwesidingo esikabili kusukela ekugcineni kwabathengi kanye nesiphetho sokusebenza kukhulisa ukuduma kobuchwepheshe be-jet boat.
Abavakashi besimanje bakhetha ukuzizwisa kwamanzi aguquguqukayo, acwilisiwe, kuyilapho abaqhubi bezohwebo begxila kakhulu ekuqineni kwesikhathi eside, izindleko zokunakekelwa okuphansi kanye nembuyiselo ezinzile. Izikebhe ze-jet zifana ncamashi nalezi zidingo ezibuyekeziwe zemakethe. Umuzwa wabo wokugibela oshelelayo noshelelayo usiza izindawo ezinhle ukuthi zidale amaphrojekthi ahlukile wokuzijabulisa emanzini futhi zihluke ezinsizakalweni zokubona izindawo ezifanayo. Ngezinhlelo zamandla ejethi ezinokwethenjelwa kanye nesakhiwo esiqinile, izikebhe zejethi zibambelela kangcono ngaphansi kokusetshenziswa njalo kwezentengiso futhi zehlise izindleko zokusebenza zansuku zonke kakhulu.
Ngaphezu kwalokho, i-jet propulsion ihlukahluka kakhulu. Ingasetshenziswa ezikebheni zezemidlalo ezincane kanye nezikebhe ezinkulu zikanokusho ngokufanayo, ezimboza ukwamukelwa kwezentengiselwano, ezemidlalo zamanzi kanye nokuhamba ngomkhumbi kwangasese. Lokhu kuvumelana nezimo okubanzi kuvumela izikebhe zejethi ukuthi zilingane cishe nazo zonke izimfuno zamanje zemakethe yasolwandle.
Imboni yezikebhe yomhlaba wonke yenze umkhuba ocacile wokuthuthuka. Izikebhe zesivinini ezejwayelekile ezongayo zizoqhubeka nokuhlinzeka ngamaphrojekthi wamanzi ayisisekelo kanye nesabelomali. Khonamanjalo, izikebhe zejethi ezisebenza kahle seziba yinketho ekhethwayo emabhizinisini amanzi okuhweba amaphakathi kuya kwephezulu. Imboni ayisalandeli ukuphindaphinda okulula kwezakhiwo zezikebhe ezivamile, kodwa ibeka phambili ukuthuthukiswa okusebenzayo kobuchwepheshe kanye nokuvumelana nezimo.
Ihambisana nokuthuthukiswa kwemboni, i-LAWADA inikeza izixazululo zesikebhe ezigcwele uhla olugcwele ezimboza izikebhe zesivinini ezivamile ezingabizi kakhulu kanye nezikebhe zejethi ezisebenza kahle ukuze kuhlangatshezwane nezidingo zemakethe ezihlukahlukene. Izikebhe zejethi zentengiso ezijwayelekile ezingama-21ft nezingu-26ft zifakwe izinjini zikadizili ze-American Mercury kanye namaphampu e-Hamilton jet, anezilungiselelo ezijwayelekile nezisebenzayo. Lawa mamodeli alinganisela amandla aqinile, umthamo owanele wokulayisha kanye nokusebenza kokuzulazula okuzinzile, okuletha izixazululo ezinokwethenjelwa zezentengiselwano kubaqhubi bamanzi bomhlaba.
Ukuze uthole ukwaziswa okwengeziwe mayelana yethu izikebhe zejethikanye nezinto zokusebenza zasolwandle ezichwepheshile, vakashela iwebhusayithi yethu esemthethweni ukuze uthole iphothifoliyo yethu egcwele yomkhiqizo kanye nemininingwane yobuchwepheshe ebanzi. Sihlinzeka ngezixazululo zasolwandle ezenziwe ngokwezifiso, ezigxile esimweni ezenzelwe ukuhweba okuhlukahlukene, ukuzijabulisa kanye nezidingo zohambo oluyimfihlo. Ithimba lethu lochwepheshe elinolwazi lihlala likulungele ukuphendula imibuzo yakho, liqinisekisa izidingo eziqondene nawe futhi linikeze izingcaphuno ezikhethekile, ezifika ngesikhathi. Zizwe ukhululekile ukuxhumana nathi ukuze uthole ukubonisana okwengeziwe ngomkhiqizo nokusebenzisana kwebhizinisi.
