Multicat Auxilia

Auxilia is the largest Multicat in the fleet, making her an ideal choice for marine projects that require ample space and exceptional lifting capabilities. With her impressive dimensions of 34.65 x 14.50 meters, Auxilia provides a spacious and comfortable living space for crew and passengers.

Whether it is offshore wind support or plough dredging, Auxilia is a reliable and powerful vessel that can handle the toughest marine operations with ease. With her strong cranes, exceptional bollard pull, and shallow draft, Auxilia is the ultimate Multicat vessel for any marine project.
