Why German mail-plane tenders were poor naval substitutes

Could Germany's existing seaplane tenders have supported naval reconnaissance and supply?

Their civilian mail-support design lacked the tempo, stores, and surge capacity required for intensive naval operations.

German mail-plane tenders were designed to turn around one or two aircraft per day. Sustained naval operations could require that many aircraft every other hour or more often. Their supplies and supporting resources reflected the lower civilian operating tempo. Wartime surge capacity cost money, giving commercial owners little reason to provide it.
