Fred,
I read all the references but nothing about the problem. I have no problem with NH criuse ship which is what they are mostly about. My problem is how do you slow down B2. I did it once using the thruttles in an unusal manner, either full throtttle to full RPM's than neutral until they drop and then full reverse
Or NEUTRAL FULL THROTLE until RPM'S build up then a FULL REVERSE! If that works, no place for it as as a Harbor Tug! It steers fine no problems!
Cheers
Alex
