Customer Questions & Answers

  • Question: What is the purpose of the center water fin?

    Answer: The center fin provides the rider with more hydrodynamic control, allowing the SUP paddle board to glide over water straighter and act as a stabilizer improving speed, steering, and maneuverability.
  • Question: Can this water fin be used with paddles boards other than SereneLife Thunder Wave models?

    Answer: No, this water fin is exclusively designed for use with SereneLife Thunder Wave Inflatable SUP Stand-Up Paddle Boards: SLSUPB10 and SLSUPB20.
  • Question: How can I troubleshoot a bent or crooked center fin?

    Answer: If your center fin becomes bent or crooked, you can troubleshoot by carefully & quickly heating the fin with moderate heat (i.e., using a hair dryer or briefly placing the fin in boiling water), then bending and aligning the center fin back into position.
  • Question: Does this fin come with the clip that attaches it to the board?

    Answer: Yes, the fin comes with the clip that attaches it to the board.
  • Question: I lost the center fin, is there anyway I can re-purchase it?

    Answer: Please contact us at [email protected] and we will send you a replacement fin. Thanks.
  • Question: I have two boards same model with two different fins. Is this the fin?

    Answer: My replacement fin works on both of my boards and they were manufactured one year apart.
  • Question: I bought a serenelife paddle board without the fin. Do you have one with a screw-in bottom?

    Answer: Please contact our support and we will send you a free replacement fin. Thanks.
  • Question: Does anyone know of an alternative fin that works for this?

    Answer: Did you contact Serenelife? I got my replacement from them. If this doesn't work, let me know.
  • Question: Why does this take so long to ship?

    Answer: I believe the manufacturer just hasn't built up his stock on the fins. I received my replacement in less than a month, so it wasn't very long.
