The DELUXE upgrade adds inside top fins and a planing surface to the existing Magnum AK and Super Magnum AK steering systems.  The top fins are positioned so that they do not come into play until the boat is off-plane and operating at slow speeds.  The position of the hull when off-plane places these extra fins in the water, and automatically out of the water again once the boat is on-plane.

This automatic increase in fin influence follows suit with the Super Fins above, as both are designed to add more steering influence when needed and automatically change that influence when the boat is on-plane.  The combination of the side fins and the top fins when driving slowly in forward or reverse, driving in minimum or no-wake zones, heavy traffic, wind, waves, or strong currents, docking, or picking up water sports participants from the water provides additional steering influence and makes performing those activities much more accurate, predictable, and responsive.

The additional planing surfaces created by the enlarged side force stabilizer brackets are reported to provide very fast holeshots and a smoother ride in choppy conditions, as well as a cleaner wake behind the boat at planing speed.
