I’m at sea looking for an etymology for < pousk > ‘ship’

What may be the earliest known vocabulary collection of early CJ (Franchère 1820:204-205)* contains this entry:

pousk, navire [‘ship’]

????

I’m not finding any leads on an etymology in Chinookan, Salish, K’alapuyan, Nuuchahnulth, English, or French. The usual suspects are exhausted.

Is “pousk” and/or “navire” a misprint, then? For what?

Ideas?

* Lewis & Clark took vocabularies of lots of Indigenous languages, apparently including early Chinook Jargon, but they got lost before they could have been published! 😒

𛰅𛱁‌𛰃𛱂 𛰙𛱁𛱆‌𛰅𛱁 𛰃𛱄𛰙‌𛰃𛱄𛰙? qʰáta mayka tə́mtəm? kata maika tumtum?  Qu’en penses-tu?  What do you think?
And can you say it in Chinuk Wawa?
