My last trip discovered that the tugs are happy to "dredge" their way along.
They do not stop if you are stuck ahead of them but barge right on through, missing your brightwork by literal inches....
Many times I would see them comming and slide carefully over until I felt the slimy, shoaling edge of the center depth
... let them pass, move into the now swirling center of the ditch and wait a few minutes in the turbulence, then tuck in a hundred or so feet behind them. It's a bit tough on the steering
system for a while but slowing down until the turbulence was tolerable and then matching their speed produced good results most often... Some would even acknowlege my presence by VHF
and chat about what was ahead.... Best one took me from the Georgia
state line to St Lucie Inlet and into Stuart FL.... He laid up at anchor
for the nights too. But I did not ground the boat at all with him ahead of me.
