Click-in Fin

(34 reviews)

The Hydrus Click-In Fin is the simplest fin system on the water. No tools. No screws. No fumbling at the shore. Press down until it clicks, paddle, pull it out when you're done.

The latest version is re-engineered to fix the original's only flaw: occasional pop-out in turbulent or shallow water. The new spring-loaded ball-bearing lock keeps the fin in place until you intentionally remove it. Click it in once and it stays there.

It fits Hydrus iSUPs (JoyRide, Paradise, AXIS, Party Board, and the rest of the line) plus any board with a standard US 10 inch fin box. Built from fiber-reinforced polymer for a balance of weight, durability, and price. The right fin for travel paddlers, beginners, and anyone who wants a no-drama setup.

What 34 Owners Agree On

Owners who switch to the click-in fin keep coming back to how quick and clean the install is: no tools, no screws, just a click. The fin holds firmly in use and releases when you want it to. Multiple reviewers report switching all their boards over to it.
