Enseigne de vaisseau non entretenu
The duties of an Enseigne de vaisseau non entretenu were the same as those of an enseigne de vaisseau entretenu (Ensign), but on a contractual basis rather than a full commission. An Enseigne de vaisseau non entretenu would wear the uniform and have authority only when on service, and was not paid when off-duty.
There was a fixed number (200) of positions for "entretenus", which required a competitive examination. The number "non entretenus" had no such limit, and one could obtain the status by a simple examination or by captaining a merchantman. This allowed the Navy to augment its ranks at a time of crisis and as the personnel of the Navy was thin and disorganised by emigration and purges.
