Which adapter do I need for my SUP / kayak / boat?

The 3 most common adapters (Slide-In/Smartlock/US-Box) are already included with the purchase of the fin.

You can find all the additional adapters that we currently offer on our website under Accessories.

You can find the exact dimensions and installation instructions for each adapter on the respective product page.

If you are still unsure, please send us an e-mail to service@jaykay-sport.de and attach a picture of your non-electric fin and the fin mounting system of your water sports equipment. In addition, es can be helpful if you let us know the make and model directly.
