S-193 M/V Leisa Florence

100' x 40' ASD-90 Class Tractor Tug

The third of four ASD-90 Class tugs for Foss Maritime, the LEISA FLORENCE was delivered in December 2020.

The ASD-90 Class tugs are a Jensen Maritime Consultants, of Seattle, Washington design. The 100’ x 40’ Z-Drive tractor tugs are built to United States Coast Guard Subchapter “M” regulatory standards, with ABS loadline certification, and UWILD notation.

The vessels are equipped with two MTU series 4000 main engines, meeting Tier 4 emission standards, coupled to Kongsberg US255 azimuth thrusters. The propulsion package will produce over 90 tons of bollard pull giving the tug exceptional pulling power and maneuverability.  The vessel is outfitted with Mackay Marine Electronics and Markey winches forward for ship assist and aft for barge towing.

The Saltchuk Marine family of companies welcomed the JAMIE ANN and the SARAH AVRICK into their fleet in April and September 2020 respectfully. The fourth and final ASD-90 tug the RACHAEL ALLEN will join the fleet in 2021.

“The launch of every vessel is a special moment in its construction, bringing the boat into it’s natural environment” said NBBB CEO Gavin Higgins. “We are very proud of the opportunity Foss has given us with this series of tugs. The teams have worked very hard to complete all three vessels in these difficult and challenging times, with the forth vessel coming shortly”.
