The Summer vibes Perform Thruster 3-Fin Set – Medium (FCiiCompatible) is designed for surfers wanting a super balanced, all-round fin with smooth speed, flow and dependable control in everyday Aussie conditions. This is the perfect template for surfers who want predictability, easy turning and reliable performance across a wide variety of waves.
These fins stand at 4.5 inches in height and feature a fibreglass construction with a Performing Core, delivering a lively yet stable feel underfoot. The combination of stiffness through the base and progressive flex toward the tip makes this set ideal for surfers approx. 60–85 kg, offering smooth acceleration and confident rail engagement.
The template offers a balanced outline with a medium base and refined tip, giving surfers a blend of drive, pivot and controlled release—perfect for upgrading the performance of a softboard or enhancing the feel of your everyday board.
This fin set is FCiiCompatible, meaning it slides straight into any Summer vibes softboard using two-tab fin boxes (all Summer vibes softboards are FCii compatible). It’s a huge upgrade from soft, flexible stock fins—delivering better speed, better hold and a far more responsive feel.

keep your gear fresh — a few simple habits
rinse after every surf. fresh water. a 60-second rinse saves gear for years.
dry in the shade, store cool. direct hot sun can delaminate darker boards. keep boards in their cover, flat or on racks — leaning on soft fins can warp them.
check your leash & fins often. look at the swivel, string and plug screws. a tired leash or a loose fin will ruin a good wave and can cost a lot more than a wipeout.
wax it right. base coat first, then top coat in small circles. when it gets grubby, strip it off with a wax comb (or park in the sun for 10 min) and start fresh.
