5 reasons of the spin-out effect

Stalling - you're pushing on the fin too hard.
Ventilation - air bubbles around the fin - from that last little chop hop, or air that got sucked under the tail of the board (because there's so much pressure on the fin).
Cavitation - you're going way too fast and the pressure around the fin is making steam bubbles. But do you really go so fast ??
Finectomy - your fin has broken off.
Weeds.
