This is the Howard Blank from New Orleans. I love to hear these big tugs when they're really working hard...especially the ones that are powered by the big Caterpillar engines. What a big powerful throaty roar they have! Some of the smaller boats are powered by Detroit Diesel...higher rpm and a screaming whine. Comparing the two...it's like the difference between a big Harley and a 125 Suzuki...I'll take the Harley (and the Cat) if you please!
Of course, I don't think the pelicans care what they sound like, they seem to disregard both with equal disdain!
