Interesting design. Somewhat larger than the common fruit carrier of the period, but not too large for that role; probably large enough to carry decent meat cargos if required, and certainly useful as a victualing auxiliary for the fleet.

A fascinating design - and a confirmation of the ability of French designers to create beautiful vessels. Very streamline moderne.

With all her gear she would also be a valuable naval auxiliary.

Tres bien! ;)
