hmmm, well, get the right person to tow you and you shouldn't have any problems (in some cases lag does happen). But the trouble is, it can be hard to find someone who has had much experience with Towing large ships in and out of ports, i always used to tow ships and i still do now, i used to be "based" in Marseille and when latitude's and Vermaas's needed to be towed in and out of North or South entrance i would help them, there was many a time when we would have to have a seperate harbour master (as i used to be harbour master regulary as well as towing people in and out and mooring them) because i was so busy, ships used to litrally queue up by the entrances waiting for me to "do my thing" and to tow them in and moor them. Then when they wanted to go out (say half an hour later) i would go back and swing them around to face the right way, stop the incoming ships and take the ship out, it was like if the amount of ships wanting to go in and out was big, i would do rotation so that say (depending on the amount of ships) i could do half an hour towing people in, and half an hour towing them out, then in some cases if ships were in need of help outside the port i would go and help them quickly and stop the incoming and outgoing traffic until the person in need of assistance was helped.
