I roto i te mara o ngā mīhini tauranga,ngā kerēne moanaHe mea nui te mahi a ēnei kerēne hei taputapu matua mō ngā kaipuke e mahi ana i ngā mahi uta me te tango utanga. E mōhiotia ana hoki ko ngā kerēne moana, ko ngā kerēne reti rānei, ka tāutahia ki runga i ngā kaipuke hei whakahaere i ngā momo utanga, ā, e kiia ana ko rātou te mīhini papa nui rawa atu mō ngā mahi hanga kaipuke. He hanganga kiato, he āhua ataahua, he haumaru, he pono, he whai hua te pūngao, he atawhai ki te taiao, ā, he tino pai te whakahaere. He maha ngā āhua o ā rātou pūma, tae atu kingā pūoro tika, ngā pūoro karu, mengā pūmau whakapiko; ā, he kanorau ā rātou tikanga whakahaere pūtake hiko, pērā i te ā-ringa, te hiko, me te hiko-waipēhi.
He taputapu motuhake ngā kerēne moana e mahi ana i ngā mahi kawe waka i roto i te taiao moana, e mahi ana i ngā mahi nui pēnei i te whakawhiti utanga i waenga i ngā kaipuke, te tuku taonga ki tai, me te whakatinanatanga me te whakaora i ngā taputapu whakahaere i raro i te wai. Heoi, he wero nui te taiao tono moana motuhake ki te whakahaere i ngā kerēne moana. I tetahi taha, he rite ki ngā taputapu kerēne whenua kāore i te kaha te mahi, me whakahaere e rātou te nekehanga o te kawenga i te wā e kawe ana kia tika ai te tūnga me te whai huatanga o te kawe; i tetahi atu taha, nā te mea kua mau ngā kerēne ki runga i ngā papa neke pēnei i ngā kaipuke, ka tino pā te nekehanga o te papa ki te nekehanga o te kawenga, ā, i roto i te nuinga o ngā wā, he rerekē te nekehanga o ngā wāhi hiki me te taunga o te kawenga i tērā o te kerēne tonu. I te wā e whakahaerehia ana, ka takahuri, ka tō te kaipuke kerēne me te kaipuke e whiwhi ana i te kawenga nā ngā ngaru o te moana, ka piu te kawenga. I te wā e hiki ana me te whakaheke ana, ka taea e te nekehanga o te kaipuke te mea ngāwari kia tukinga anō te kawenga kua hikitia ki te papa, ka mea rānei kia iri anō te kawenga kua whakahekehia engari kāore anō kia wehea mai i te matau ki te rangi, ka tūkino i te haumaru mahi. Ina koa i te wā e tuku ana i ngā matā i waenga i ngā kaipuke, ka arahi pea tēnei nekehanga hono ki ngā hua kino ake. Nō reira, kua aro nui te ao whānui ki te whakahaere i ngā kerēne moana mai i ngā rāngai miihini moana hōia me ngā rāngai tangata whenua, ā, he mea nui rawa atu te rangahau i te whakahaere i aua pūnaha kore-raina, kāore i te tino kaha te hononga i raro i ngā raruraru motuhake, ā, he mea nui hoki ki te ao whānui.
Ko te whakahaere o ngā kerēne moana e aro nui ana ki ngā āhuatanga e rua: te whakahaere poutū hei whakaiti i te pānga o te nekehanga o te waka me te ārai-nekehanga taha hei pehi i te nekehanga o te kawenga. Mō te whakahaere poutū, ko te tikanga noa ko te hono i te kaipuke whiwhi mā te hanganga miihini o tekaipuke kerēni, ka rongo i tā rātou nekehanga whanaunga, ka tukutahi i te huringa o te roa o te taura hiki me te nekehanga tō o te kaipuke whiwhi, ā, mā te pera ka utua te nekehanga whanaunga i waenga i ngā kaipuke e rua, ka oti hoki te hiki me te kawe i te kawenga. Heoi, he whakaritenga motuhake tā tēnei tikanga mō te hanganga miihini o te kerēni, ā, he nui ngā here e pā ana ki te taumaha hiki.
Ngā Aratau Hanga me te Whakahaere
Mō ngā wāhanga, he taputapu kawe utanga tuku iho te taputapu retireti, kei roto ko te retireti, te pūmau utanga (te pou utanga rānei), ngā taura, me te wini (te wini utanga rānei), me ētahi atu. Ahakoa he maha ngā taura, he uaua hoki te whakahaere, kua whānuitia te whakamahinga nā te mea he māmā te hanganga, he ngāwari te hanga, he iti hoki te utu. E rua ngā momo uta me te tango utanga mā te whakamahi i te taputapu retireti: te mahi pūmau kotahi me te mahi pūmau takirua.
Ko te mahi pū kotahi e whakamahi ana i te taura kotahi hei uta me te tango i ngā utanga. Whai muri i te hiki i te utanga, ka tōia te taura tangata kia nekehia te utanga me te pū ki waho, ki te taupoki rānei, kātahi ka tukuna te utanga, ā, ka hurihia te pū ki tōna tūranga taketake, me te mahi anō i tēnei tukanga. I ia wā, me huri te pū ki te taura tangata, ka iti te whai huatanga me te kaha o te mahi. Ko te mahi pū takirua e whakamahi ana i ngā pū e rua, ko tētahi kei runga ake i te taupoki, ko tētahi e toro atu ana ki runga ake i te taupoki. Ka mau ngā pū ki tētahi tūranga mahi me ngā taura tangata, ā, ka honoa ngā taura hiki o ngā pū e rua ki te matau kotahi. Mā te hoki whakamuri me te tuku i ngā taura hiki e rua, ka taea te tango i ngā utanga mai i te kaipuke ki te tauranga, te utaina rānei mai i te tauranga ki runga i te kaipuke. He teitei ake te whai huatanga o te uta me te tango i ngā utanga o te mahi pū takirua i te mahi pū kotahi, ā, he iti iho hoki te kaha o te mahi.
I puta mai ngā taputapu derrick pai ake i muri mai. Ko te taputapu derrick hiki rua-whakakī kua whakapai ake i te taputapu derrick kotahi-pūma e whakahaerehia ana, me te taura hiki anake me ngā huinga e rua o ngā hiki tāpiri maui me te matau e wehea ana. Ko te derrick e whakahaerehia ana e te wini hiki kotahi me ngā wini hiki tāpiri e rua, he ngāwari ki te whakahaere, ā, he pai te uta me te tango. Ko te taputapu derrick Abel kua whakapai ake i te taputapu derrick rua-pūma e whakahaerehia ana, me te wini hiki, ngā hiki tāpiri, me ngā wini taura tangata. Ka taea e ia te whakanoho tere i te derrick ki tetahi tūranga me te awhina o ngā wini, ā, ka taea hoki te hiki me te whakaheke i te utanga ki ngā wāhi pumau i roto i te radius mahi o te derrick, he taahiraa nui tēnei ki te aunoatanga katoa o te uta me te tango utanga.
