When the boat moves through the water, the water is pushed under and around the boat. The water will eventually come together directly behind the center of the boat. The water coming up below the boat will rise vertically with the prop wash and create a "V" pattern wake. The SuckGate displaces the water coming around the side of the boat so the water from both sides does not come together. This creates an unbalanced wake. The water coming up below will rise with more force creating the "Curl" and "Push" that allows you to Wakesurf! Prices are in canadien.
