French Steam Tugboat Actif 1939
French ministry of defence used to publish these plans but now they shut their servers down. Actif is a steam tug, and the plans are original shipyard blueprints. Unfortunately i couldn’t find any information about this tug. You’ll notice that there are also mine layer rails added to the plans. So probably this tugboat was also used in mine laying operations.
Excellent site will be checking it out in my search for plans
