I've done a 180 with the 220 in a 60 foot wide bayou. Use to bring all
the fuel to Southern Pacific Railroad up Buffalo Bayou close to down
town Houston. So narrow I always had to break down the tow and push it
back out from the other end. Always drew a big crowd on the bridge I
would lay the barge against.

Also had to shoot into a slip 100 foot wide with a 5 kt side current ,
Had to usually start setting of for that trick 1/2 mile ahead of the
slip.

As for doing a 360 in a 225 foot area it is impossiable since the tug
was 60 foot.

A smarter move than a bow thruster would be flanking rudders IMO.

Is your thruster going to be electric?

Some of the 310 ft supply boats I ran had 6-71 detroit bow thrusters.
In a hard side current at the rig they were useful but rattle the damn
boat so much it drives you crazy. After 4-5 hours of that your damn
happy to be offloaded or loaded.
Problem with bow thrusters are the props tend to cavitate.
