Why Boost Fin Plus
Catch waves you used to watch pass
20 lbs of thrust fills the gap between "almost had it" and "dropping in." Paddle less, ride more, and stop burning energy on waves that don't come to you.
Disappears when you don't need it
The folding propeller tucks flat against the fin body between waves. Zero drag. No seaweed tangles. It only works when you tell it to.
Built for real sessions
2-hour battery. Hydrodynamic shape tested in ocean conditions. This isn't a novelty — it's equipment that performs on dawn patrol, in choppy conditions, and through back-to-back sets.
On any board in 5 minutes
No drilling. No permanent mods. Choose your adapter, click in, and go. Move it between boards whenever you want.
Performance meets simplicity
More waves. Less effort. No compromises.

"I'm 52 and was getting tired just paddling out. Boost Fin Plus changed everything — I'm catching waves I haven't been able to reach in years. Best purchase I've made for surfing."

"Was skeptical, but the folding propeller is legit. Zero drag between waves, and the extra push gets me into position every time. My session count has genuinely tripled."

"Use it on my SUP for longer paddles. The 2-hour battery means I never have to cut a session short. Installation took maybe 3 minutes the first time."

"Solid build quality. The hydrodynamic design really does eliminate drag when the prop is folded. Only wish it came in a smaller size option for performance boards."
