Doesn’t sliding sideways qualify as Park Assist?
I’m guessing bow side-thrusters? Come on Swabs, splain this.
Actually, it’s a “stern side-thruster”.
No thrusters here, it’s basically a function of the fact that a turning ship rotates around a pivot point. Everything forward of the pivot point moves the direction of the turn, everything aft moves the opposite direction. There is also forward (advance) and sideways (transfer) motion in every turn. Laying out tracks on harbor charts I used advance and transfer tables that were entered with degree of turn, degree of rudder and speed to calculate where the ship need to start to turn to end up on the desired track.
