Speaking of major improvements. This extension on the end of the line holder that brings the line below the water line allows the front of the boogie to keep the nose down while also allowing the battery case to be pulled back.
So here’s my analysis. Having weight further back allows the boogie to keep its nose above the waterline at the bottom of the face of the wave/swell. So by placing the tow line below the plane of the board, water starts become a lot easier with the nose more likely to stay low. With weight back it handles better on the bottom face of swell and is less likely to duck dive.
