Almost any high performance bass boat hull with enough lift will chine walk to some extent at high speed........Chine walking is a result of the torque from the prop wanting to throw the boat off the "pad"..The Pad basically being the last few feet of the bottom of the boat. Chine, refers to the 90 degree angles created where the bottom of the hull meets the side, most boats will have a number of chines on the bottom, 3 to 4 before the actual hull meets the side of the boat..these chines help in cornering and handling.
To get a boat " on Pad " the hull of the boat has to have enough lift when the motor is trimmed up that most of the hull is out of the water, and the boat is " balancing " on the last few feet of the hull, breaking free from the friction created by the water.
Water creates a tremendous amount of friction on the hull, slowing it down. Trimming the motor up and getting the boat on pad will allow the hull to lift out of the water , reducing friction and picking up MPH and using less fuel to push the boat
The Chine Walking ( or nose wobble/ prop walk ) happens when the boat is on pad and the clockwise rotation of the prop keeps throwing the boat off the pad. To correct the walk, make very small left hand downward movements on the steering wheel, this will counter the props right hand movements and you will be able to balance the boat on the pad.
You Can Not drive thru chine walk with more trim or power.......that can create a dangerous situation where you can lose control of the steering at high speed.
If the boat starts to violently chine walk DO NOT dump the throttle, this will cause the nose of the boat to drop quick and the boat may bow hook and you will be sitting 180 degrees from where you where. If you are still in the boat. Trim down quickly while keeping the throttle steady, this will drop the boat off pad and slow you down enough to eliminate the walk.
If you are not getting enough hull out of the water to break friction chances are you are not set up right, same if you are having chine walk at lower speeds, generally the motor is set too low on the transom/jack plate and needs to be raised. If you have a jackplate you can do this in 1/4 " increments, testing steering/chine walk and watching your water pressure..keep raising it until you can get on pad and still have good water pressure at WOT ( 14 - 15 psi ).....
Watch this video , it is an excellent tool to learn how to correct chine walking at speed.....watch the drivers hands and notice the Small Left hand corrections he is making on the wheel and how fast the boat reacts and straightens right out.......takes some seat time and practice, but once you get the feel you can drive virtually any boat and correct the chine walk.
