When it comes to choosing fins for your inflatable paddle board, do you know which is best for you? Depending on your needs depends on whether you decide on permanent or removable fins. For instance, removable fins can change out for different paddling experiences - surfing, touring, or down river. You decide upon the set up that will meet your needs. It's as easy as that. \r\nKeep in mind though, that removable fins can break off in rough waters and then get lost. Permanent fins are, well, more permanent. \r\nRegardless of which you choose, remember, without fins, you're apt to go in circles.
