He rerekē ngā momo whirihoranga o ngā aho ngongo ruku wai pērā i te 'S', te 'Lazy', me te 'Chinese Lantern'. Ka hangaia te whirihoranga mā te tāpiri i ngā poraka pōtae ki ngā ngongo ruku wai, ko te 'Chinese Lantern' te momo whirihoranga e whakamahia whānuitia ana. I roto i te pūnaha HUARĀKAU, ka mau te pōtae here kotahi-ira ki te papa moana me ngā mekameka punga e 4-8. He papa hurihuri me te hononga hiri hurihuri kei runga i te pōtae. Ka honoa te papa hurihuri o te poti rokiroki hinu me te pōtae kotahi-ira mā te taura waea, te ringa maitai rānei, ka taea te huri 360 nekehanga, pērā i te 'weathercock', kia mau tonu ai te tūranga me te iti rawa o te kaha. I te wā e mahi ana, ka uru te hinu mata ki te pōtae mā roto i ngā aho ngongo mānu mai i te poti rokiroki hinu, i te kaipuke hinu rānei, kātahi ka uru mā roto i te hononga hiri hurihuri i te pūwāhi kotahi ki ngā aho ngongo ruku wai me ngā paipa ruku wai, ā, ka tae atu ki te rokiroki hinu tauranga.

Ko te arai o ngā ngongo momi me te tuku hinu he mea hanga ki te elastomer me te papanga e tika ana mō te mahi tonu i te tere rere o te 21 mita/hekona. Mena e hiahiatia ana he tere neke atu i ēnei uara, me tohu e te Kaihoko. Ko ngā mata o roto, o waho hoki o ngā hononga pito me ngā flanges (tae atu ki ngā mata flanges) e tiakina ana e te whakawera wera e ai ki te EN ISO 1461, mai i te waikura i puta mai i te wai moana, te kohu tote me te reo tuku.

Mā te whakawhirinaki ki ngā pokapū hoahoa kei Hamburg, Houston me Singapore, ka taea e CDSR te whakarato ki ngā kiritaki he rangahau whirihoranga, he rangahau kaupapa hangarau, he kōwhiringa momo ngongo, he hoahoa taketake, he hoahoa taipitopito, he hoahoa tāutanga me ētahi atu ratonga mō ngā aho ngongo ruku wai.
