I don’t know if you surf anymore because those pics are very old now, but here’s a few longboarding tips:
*Turn off the bottom, pick the higher line and walk further towards the nose.
*You’ve lost heaps of speed because your legs are static there.
*Note the amount of nose out of the water making you fall back.
Recap: take off quick, feet need to be 3/4 back off the bottom, pick a line and step forward quickly towards the nose. After the head-dip or nose-ride, quickly step back again to regain manoeuvrability and turning ability off the tail. Rinse and repeat old man.
You’re welcome!
