Then we were around 20 lbs force on the string. My son wants to edit the video and we don't have pictures of the action. The dock had a boat in the middle so we were running up and down the beach. Sand flies were bothering the boys so experiments were cut short. We will try again.

Starting to move and the angle is good:
Every wave tank should have palm trees:
