hello Bottman, damage was not a problem, of course I was in calm water in the harbor, but this tug does not seem to have sufficient rudder power to tow this way, I was able to make it work but I had to put the rudder hard over to port with stbd engine full ahead and port out of gear to maintain my heading, speed seems a little slow as well, a maximum of only 2 to 3 kts. this way and approx. 4 kts. pushing ahead or towing astern. I was expecting 7 to 8 kts. towing and maybe 9 pushing ahead.
playing around with a tandom tow now.
