The Summer vibes Power Thruster Fins Medium – FCiiCompatible are built for surfers who want maximum drive, hold and power through their turns. With a strong, forceful template, this fin set is ideal for surfers who push hard on rail and want confidence in punchy beach breaks and clean point waves.
At 4.5 inches in height and constructed using a Fibreglass + Performing Core, these fins deliver excellent stiffness and energy transfer. Best suited to surfers around 60 –85 kg+, they provide powerful projection, strong bite and added stability at speed.
The template features a wide base for acceleration with a refined tip for controlled release and responsive turning. This is the perfect upgrade for surfers wanting a more aggressive, power-driven feel than a balanced “all-rounder” fin.
These fins are FCiiCompatible, fitting all Summer vibes thruster surfboards that use the two-tab fin system. Compared to basic composite fins, the Power Thruster delivers significantly more speed, hold and drive.

These fins excel in punchy conditions, delivering improved hold, acceleration and rail engagement compared to standard composite fins.

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.
