You know that in the US the manual is not required to be on board if
the limitations are properly marked via placards and decals.

That's news to me! Last I read, if it was listed in the TCDS or if the
manual (POH) said it had to be in the glider, then it needs to be in
the glider regardless of what is placarded. And the POH specifies the
minimum placards.
