SUP Fins

To determine which iSUP fin replacement is appropriate for your inflatable paddle boards, see our Tower iSUP fin replacement page.

SUP fins provide stability and traction to your stand up paddle board. Fins aid in steering, and paddling in a straight direction, allowing you to stand up paddle surf without spinning out when you turn. More fins in the water = more traction and grip. We highly recommended that every stand up paddle board should have at least one fin installed while in use.
