Possibly *Qb5-17 should be read as 'Hanga Hoonu'. It is the first of the two glyphs denoting day 360 ( = 592 / 2 + 64). The glyph type haga rave could have been used in compounds in order to be read as 'haga'.

The explorers stayed and rested at Hanga Hoonu for five days (according to Manuscript E). They fetched fire from Hanga Te Pau to cook all the fish they had caught:

'... They prepared the fish in the fire on the flat rocks, cooked them, and ate until they were completely satisfied ...'

5 days are like the difference betwee 360 and 365, a time outside the ordinary calendar, when time in a way stands still. Honu at right in *Qb5-17 has no legs, it is the variant which I have named Rogo. The fire on the flat rocks probably allude to winter solstice.
