What Are Coastal Rowing Fins?
Coastal rowing fins are specialized rowing boat fins designed to handle the unique demands of beach sprint and open-water rowing.
Unlike flatwater rowing fins, coastal rowing fins are built to perform in waves, wind, shallow launches, and rough water. They prioritize directional stability, predictable handling, and durability — even when boats are pushed through surf or landings are less than perfect.
Key characteristics of coastal rowing fins:
- Reliable tracking in waves and cross-chop
- Stability during powerful beach sprint starts
- Reduced drag at race pace
- Strong materials for transport, surf launches, and debris impact
Whether you’re training, racing, or preparing for competition day, the right fin plays a crucial role in keeping your boat fast and under control.
Choosing the Right Fin for Coastal Rowing
Choosing the right coastal rowing fin depends on conditions, boat type, and how you train or race. The goal is to find the best balance between stability, speed, and forgiveness — without making fin choice a constant decision.
Boat Type & Setup
Boat size and crew configuration also play a role:
- 1x (single scull)
Lighter and more reactive. Often benefits from slightly smaller or more efficient fins that allow quick acceleration and easy course corrections. - 2x (double scull)
Heavier and more powerful. Typically benefits from a bit more fin depth or surface area to maintain tracking and stability, especially in cross-wind or open water.
Fin System Compatibility
Coastal rowing boats use different fin box systems depending on the manufacturer. Our fins are compatible with the most common standards used in coastal rowing.
US-Box System
Widely used on coastal rowing boats from manufacturers such as Filippi, Empacher, Liteboat and Carlo Zezza. Allows easy fin swaps and precise positioning — ideal for training and racing.
Swift Racing Fin
Proprietary fin system used on Swift Racing coastal rowing boats. Designed for a secure fit during beach sprint starts and surf conditions.
If you’re unsure which system your boat uses, we’re happy to help.
Performance Benefits in Rough Coastal Water
Coastal rowing demands confidence in changing conditions. Our fins are designed to support your rowing — not distract from it.
- Stable tracking: Keeps the boat running straight through waves and cross-chop.
- Low drag at race pace: Efficient outlines reduce resistance without sacrificing control.
- Predictable handling: Smooth, calm response during accelerations, turns, and starts.
- Durable construction: Built to withstand surf launches, transport, and everyday use.
From training sessions to competition day, the focus stays where it should be: on your rhythm and power.
COASTAL ROWING FINS VS FLATWATER ROWING FINS
While they may look similar at first glance, coastal rowing fins are designed for a very different environment.
- Deeper and more stable outlines
- Stronger materials for impact resistance
- Optimized rake for open-water conditions
- Built for beach sprint starts and surf landings
Flatwater fins prioritize minimal drag in calm water. Coastal rowing fins prioritize control when conditions are unpredictable.
Used by Athletes
Our coastal rowing fins are developed with feedback from competitive athletes and coaches. Early prototypes were tested during training sessions with members of the German Rowing Federation national team.
Real-world prototype testing helps refine key performance factors such as tracking, directional stability, and control in rough coastal water. Insights from our river surfing fin designs also inform the hydrodynamics and performance of our coastal rowing fins.
Coastal Rowing Fin FAQ
-
Coastal rowing fins are designed for waves, wind, and shallow launches. They focus on stability, durability, and predictable handling rather than absolute minimum drag.
-
Most rowers use fins between 6.5″ and 8.0″. Smaller fins suit shallow water and beach sprint starts, while deeper fins offer more stability in rough conditions.
-
Many coastal rowing boats use US-Box or Swift Racing fin systems. If you’re unsure, send us a photo of your fin box and we’ll confirm compatibility.
-
US-Box fins slide into the fin box and are secured with a plate and screw. Swift Racing fins use a proprietary locking system.
-
High-impact, reinforced materials like fiberglass-reinforced nylon or recycled industrial polymers perform best in coastal rowing. They resist breaking on beach launches, handle debris, and maintain their shape under stress. Our fins are made from recycled automotive materials — proven durability with sustainability.
Designed in Munich — Inspired by the Eisbach
Eisbach Riders was born on the river.
Before coastal rowing, before open water racing: there was river surfing in Munich.
That background shapes how we design fins: practical, durable, and tested where conditions are never perfect. Our fins are developed in Germany, produced with a focus on longevity, and refined through real-world use.
