The Dynafiber Weed Fin is a vinylester weed fin designed for spots with seaweed, seagrass, and shallow water. The strongly swept-back leading edge allows seaweed to slide off instead of getting caught, keeping the board fast and controllable even where a straight fin would get bogged down.
It is available in sizes from 18 to 30 cm and with three box types: Powerbox, Tuttle Box, and US Box.
Key Features
Anti-weed Geometry
- Leading edge with a strong rake: seaweed and seagrass slide towards the tip and break off.
- Reduced draft: for the same surface area, the fin works shallower, making it useful on sandbanks and lagoons.
- Wide base and thinner tip: good upwind drive at the base and a little flex at the tip.
Vinylester Construction
- Stiffer than a plastic fin and more forgiving than G10.
- The flex at the tip absorbs pressure peaks and makes the fin progressive, reducing spin-outs.
- Repairable: minor knocks on rocks or sand can be fixed with a file and sandpaper.

How to Choose the Size
A weed fin is not chosen with the same length as a straight fin: thanks to the rake, it has more surface area for the same length. As a rough guide, a weed fin works like a freeride fin about 10 cm longer (a 24 cm weed fin is close to a 34 cm freeride fin). If you usually use a 36 cm freeride fin, go for a 26 cm weed fin.
Who It Is Recommended For
- Freeride windsurfers who ride in lagoons, lakes, or spots with seagrass.
- Those who often go out in shallow water or near sandbanks and sandbars.
- Those looking for a reliable and comfortable anti-weed fin in chop, without the cost of G10 or carbon.
Q&A – Frequently Asked Questions
Q: What is a weed fin?
A: It is a fin with a leading edge that is swept back at a steep angle, which prevents seaweed and seagrass from accumulating. It is used in spots with vegetation and in shallow water.
Q: Which Box Type Should I Choose?
A: It must match the fin box on your board. Powerbox, Tuttle Box, and US Box are not interchangeable: check the box type under the board or in the manufacturer's specifications before ordering.
Q: What Size Weed Fin Do I Need Compared to My Straight Fin?
A: Generally about 10 cm shorter than the freeride fin you use. For example, instead of a 36 cm freeride fin, choose a 26 cm weed fin.
Q: Is Vinylester Better Than G10?
A: Vinylester is more flexible and comfortable in chop and is more affordable; G10 is stiffer and faster, suitable for heavier riders or those focused on speed.
Q: Can I Use It Where There Is No Seaweed?
A: Yes, it works like a forgiving freeride fin, but in clean water a straight fin generally offers more top speed and upwind angle.
Q: How Do I Repair It If It Hits the Bottom?
A: Minor damage to the edge can be fixed with a fine file and wet sandpaper; after every session in the sea, rinse the fin and screws with fresh water.
Q: Are the Screws Included?
A: It depends on the box system. If you need replacement screws for Powerbox, Tuttle, or US Box, you can find them among the fin accessories on ZZSURF.
