Just thought this was a good video showing how to correct chine walk in the proper manner with just steering adjustments.  I always tense up and do the wrong thing.  This video shows you that it usually won't get too out of control unless you do something stupid like trim down and throttle down at the same time.

Chine Walk:  Severe side-to-side rolling of the boat.  It actually means to roll from chine to chine but it is also used for less severe rolling, although always severe enough to scare or cause a loss of control.  Essentially, this is a characteristic of high speed V-bottom boats, where the boat is balancing on the pad or very bottom, further aggravated by the drag of the lower unit.

Chinewalking must be compensated for by steering input from the driver.

Note: As a general rule, a properly setup bass boat will chinewalk less than one that has not been setup properly.

 

If it's a pad-V and it don't chine walking, it ain't going fast enough to fully get up on the pad.   Like Cart7 mentioned, setup and load balance goes a long way toward minimizing it, but learing to drive is the only way to stop it.  Mine might run 75 one day and never try to walk and then want to get squirrely the next time at 65.
