Ko te tinana matua o te pokepokea werohanga parepare o mua o te motuka e whakamahi ana i te hangarau mata wehewehe ā-roto, mā te oma wera, me te whakahaere takirere raupapa ki roto i te kāpia. I ngā taha e rua o te taipana me te tihi nui e anga ana ki runga e anga ana ki runga e tika ana ki runga o te hanganga, nā te tuanui tika me te tuanui e anga ana te pokepokea he tino nui, he anga e anga ana me te anga e tika ana mā te 50 ki te 60 mm, he tokotoko pana taha e 25 ki te 35 mm, he anga nui e anga ana mā te koki 16 nekehanga, mō te koki pana neke atu i te 12 nekehanga ki runga ake, me hoahoa te hanganga pae arataki, kia hangaia ai te hanganga pae arataki tihi nui e anga ana ki runga o te pokepokea. Ko te rahi mōrahi o te pokepokea ko 2500 × 1560 × 1790mm, ā, ko te taumaha he tata ki te 30T. Tirohia te Pikitia 22 mō te hanganga pokepokea. E whitu ngā kōhao taha i te taha o waho o te parepare o mua, ā, ko te hanganga ngira rapa e whakamahia ana i roto i te pokepokea. Ko te hoahoa o te pokepokea e whakamahi ana i te hangarau mata wehewehe ā-roto matatau. Ko te mea e kiia nei ko te hangarau wehewehe ā-roto e pā ana ki te wehewehe o waho, ko te tikanga ko ngā hua whānui e rite ana ki te āhua whakaputa mōrahi o te hua mō te raina wehewehe mate pumau, koinei te wehewehe o waho, ko te pokepokea whānui e rite ana ki tēnei ara wehewehe. Ko te wehewehe o roto ko te huna i te topenga wehewehe ki te mata kore-āhua o te hua (arā, te taha B, te taha C rānei, ko te mata āhua ko te taha A), ā, kāore e kitea te topenga wehewehe i muri i te huihuinga ki te waka, kia kore ai e pā ki te āhua. Hei whakatutuki i tēnei mahi, mā te hanganga pokepokea ka whakahaere i te tihi piko whakawhiti (runga tika rānei) i roto i te mahi reri tuarua, kia whakarite ai i te whakarerekētanga me te tangohanga o ngā wāhanga kirihou, ko te whakamahinga o tēnei hangarau reri tuarua e whakahaerehia ana e te tikanga, e kiia nei ko te hangarau wehewehe o roto. I roto i te hoahoa o te pokepokea werohanga motuka, he mea hanga motuhake te hangarau wehewehe o roto mō te parepare motuka. Heoi, he uaua ake tēnei hangarau i te parepare wehewehe o waho i roto i te uaua me te hanganga, ā, he nui ake te mōrearea hangarau. Ka nui ake te utu me te utu o te pokepokea i te parepare wehewehe o waho. Heoi, nā tōna āhua ataahua, e whakamahia whānuitia ana i roto i ngā motuka utu waenga me ngā motuka utu nui.
Mō ngā wāhanga kirihou o te parepare waka, e rua ngā huarahi mō te wehewehenga o waho me te wehewehenga o roto. Mō te whānuitanga nui o te taha whakararo o te parepare, arā, ka taea te whakamahi i te wehewehenga o waho, te wehewehenga o roto rānei. Ko te whiriwhiri i ēnei tikanga wehewehenga e rua e whakawhirinaki ana ki ngā whakaritenga o ngā momo waka a te kiritaki whakamutunga i runga i te parepare. Ko te tikanga, ko ngā waka Pākehā me Amerika te nuinga e whakamahi ana i te hangarau wehewehenga o roto, ko ngā waka Hapanihi ia e whakamahi ana i te hangarau wehewehenga o waho. He painga me he ngoikoretanga ngā momo tikanga wehewehenga e rua. Me mahi te parepare o waho ki te aho whakapiri, ka whakanui ake i te tukanga tukatuka, engari he iti ake te utu me te uauatanga hangarau o te parepare o waho i roto i te pokepoke i tērā o te parepare o roto. Ko te wehewehenga o roto o te parepare mā te hangarau whakahaere reriwe tuarua, he werohanga parepare kotahi te wā tino pai, kia pai ai te āhua o te parepare, kia kore ai e pau te tukanga tukatuka me ngā utu tukatuka o ngā wāhanga kirihou. Engari ko te ngoikoretanga he nui te utu pokepoke, he nui ngā whakaritenga hangarau pokepoke.
