The Pusher 4 is a mid-ranged board that evolved after making shorter and shorter versions of the Pusher model. I found with these smaller planshapes, the single fin did not have the effortless trim speed I had been accustomed to with the longer shapes. Reducing the planshape size of the pusher and adding the quad fin set up allowed more versatility and ability to generate speed - still without having to hop around. This has become a popular model due to the broad range of waves it can surf and the ability to still get aggressive on a mid-ranged board. A true all terrain vehicle.
