S-156 M/V DELTA CATHRYN
30.48 m (100'00")
NBBB completed the fourth of five Bay Delta Tractor Tugs in 2009, the Delta Cathryn. Although she has a sweet name, this tractor tug is one of the biggest and baddest tractor tugs out there. The propulsion package, containing two 3400 HP Caterpillar diesel engines coupled to a Rolls Royce Z-Drive system produces 94 tons of bollard pull. Equipped with both a powerful bow and stern winch outfits this tractor tug for any job!
