Here’s a few things to look in regards to fins for in buying an Inflatable SUP
Many inflatables don’t allow you to use fins from other companies as their fins are molded on the board or have specific removable fins (black plastic with removable tab to lock in fin). One of my students purchased a Red Company board that allowed him to replace the fin but the fin box is so short that he’s limited to a specific type or length of fin.
Personally, I prefer to remove my fin for easier storing and like to be able to choose the type of fin I want for various types of paddling.
Removable Fin Issues:
Some long board fin boxes are too loose to tight for removable fins. I’ve experienced both. In once case the fin box is too wide thus won’t take any quick release attachments, only the fin screw and plate. In another the box is too narrow thus won’t take a standard fin as well. Sometimes you can deflate the board a bit, put the fin in, then inflate to full PSI again.

|Fin molded into the board (or glued)|
