The third of four ASD-90 Class tugs for Foss Maritime, the M/V Leisa Florence was launched at Nichols Brothers Boat Builders (NBBB) today November 18, 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.
Foss welcomed the M/V Jamie Ann and the M/V Sarah Avrick into their fleet in April and September respectfully, the M/V Leisa Florence will join the fleet in December after final outfitting and trials are completed at NBBB.
“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 team have worked very hard to complete all three vessels in these difficult and challenging times, with the forth vessel coming shortly”.
NBBB is the Pacific Northwest’s premiere custom boat builder with over 55 years’ experience in vessel construction, repair and conversion.
