I ēnei rā, me te whanaketanga o te ōhanga me te hiahia o te tangata mō te kawe waka, kei te hangaia e ia tāone te tereina raro whenua tetahi i muri i tetahi,Puranga rino Larsenme noho hei rauemi hanga whare nui i roto i te tukanga hanganga o te ara raro whenua.
Puranga rino LarsenHe kaha teitei, he hononga piripono i waenga i te puranga me te puranga, he pai te pānga wehenga wai, ā, ka taea te whakamahi anō. Ko ngā momo wāhanga noa o ngā puranga rau maitai he āhua-U, he āhua-Z rānei. E whakamahia ana ngā puranga rau maitai āhua-U i roto i te hanganga rerewē raro whenua i Haina. Ko ōna tikanga totohu me te tango, he rite tonu te whakamahinga mīhini ki te puranga maitai-I, engari ka taea te wehewehe i tōna tikanga hanga ki te kōhao puranga rau maitai papa-kotahi, te kōhao puranga rau maitai papa-rua me te mata. Nā te hohonu o te poka turanga i te wā e hangaia ana te rerewē raro whenua, kia tika ai te poutū me te hanganga watea, kia taea ai te kati me te katia, ko te hanganga mata te nuinga o te wā e whakamahia ana.
Ko te roa o te puranga rino Larsen he 12m, 15m, 18m, me ētahi atu. Ko te roa o te puranga rino hongere he 6 ~ 9m, ka whakatauhia te tauira me te roa mā te tatau. He pai te pakari o te puranga rino. Kia oti te hanganga o te poka turanga, ka taea te tango i te puranga rino me te hangarua anō. He watea te hanganga me te wā hanga poto; Kāore e taea e te puranga rino hongere te aukati i te wai, i te wāhi he nui te wai whenua, me mahi ngā mahi wehe wai, me te aukati ua rānei. He ngoikore te kaha piko o te puranga rino hongere, e whakamahia ana mō te poka turanga, te awaawa rānei he hohonu ≤4m, ā, me whakatakoto he punga tautoko, he punga kukume rānei ki runga. He iti te pakari o te tautoko, ā, he nui te whakarerekētanga i muri i te keri. Nā te kaha o te piko, ko te nuinga o te wā e whakamahia ana te puranga rino Larsen mō te poka turanga hohonu 5m~8m me ngā whakaritenga taiao iti, i runga i te tāutanga tautoko (punga kukume).
