Sup Fin

🦈 SUP Fins – stability, control & the best paddling experience

Our SUP Fins collection includes essential components that improve your board’s stability, tracking and overall performance on the water. The right fin dramatically affects how well your board holds a straight line, how stable it feels, and how easily you can manoeuvre.
The collection includes US Box, slide-in, river and grass (weed) fins, compatible with most SUP boards.

⭐ Types of SUP Fins

🔧 US Box Fins

• the most universal and widely used system

• installs with a screw or tool-free mechanism

• allows switching between different shapes and sizes

• ideal for touring, recreational and advanced paddling

🔩 Slide-In (Push-In) Fins

• quick installation without tools

• commonly used on family and recreational SUP boards

• perfect for beginners and occasional paddlers

🌊 River Fins – for shallow water & fast-moving rivers

River (shallow water) fins are shorter, rounder and designed to:

• avoid snagging on rocks or debris

• perform well in shallow water, rivers and streams

• maintain stability without risking fin damage

Ideal for paddlers exploring rivers, canals or very shallow lakes.

🍃 Grass/Weed Fins – for lakes with vegetation & sea grass

Grass (weed) fins have a more angled, raked profile, preventing:

• grass and weeds from catching on the fin

• drag and loss of speed

• sudden stopping or instability

Perfect for grassy lakes, coastal areas with seaweed, or any location where a standard fin gets stuck easily.

📏 Bigger Fin vs. Standard Fin – what’s the difference?

✔ Larger (deeper) fin

• improved tracking (board holds a straight line better)

• increased stability, especially on touring boards

• great for long distances and flat water

✔ Smaller / standard fin

• easier manoeuvring

• ideal for playful recreational paddling

• perfect for shallow water, small waves or beginners

Choosing the right fin can make your SUP feel faster, more stable or more agile, depending on your goals.
