Hey guys does anyone have any tips for not bogging the rail on the bottom turn on smaller days?

For reference im surfing a 7’2 NSP funboard.

I try to drop to the bottom of the wave before starting the bottom turn to get the most speed possible, but anytime I lean into the turn it just sinks my rail and I either lose all my speed or just completely push the board under water.

What am I doing wrong, and are there any drills that I could be doing to work this out?
