Datapoint Pidgin Hawaiian/uː - long high back rounded vowel
Vowel length is phonemic in the lexifier (as is the case with hūhū) but was likely lost to an unknown extent in the pidgin (written sources also do not mark vowel length which is why length is not indicated in my texts), as orthographic evidence shows that diphthongs were also often reduced. The transcription of Tomas Quihano's Pidgin Hawaiian indicates long vowels.
