A wake control system aft of the driveshaft, propeller, and rudder of a vessel includes a fin base and at least one fin slidingly engaged with the fin base. The fin(s) are vertically oriented and extend down into the water surface. The fins are transversely adjustable along the fin base to redirect a wake generated by the boat. In other embodiments, the control system comprises a starboard fin tab adjacent to a port fin tab, each of the independent fin tabs hingeably attached to the aft section of the hull, at the transom. Each fin tab includes at least one extending fin. Fin tabs are selectively deployable and retractable into and out of the water surface to redirect a wake generated by the vessel from one side to the other. A novel underwater exhaust system redirects exhaust depending on speed of the vessel and complements the wake control system.
