DYNAFIBER WEED FIN TT

The Dynafiber Weed Vinylester Fin is a specialized anti-weed solution designed for spots with heavy seagrass or shallow water. It is part of Dynafiber’s accessible range, providing a significant performance boost over standard plastic fins without the high cost of G10 or Carbon.

Here is the breakdown of its design and performance:

1. Anti-Weed Geometry

• High Rake Angle: The leading edge is heavily swept back (usually around 45° to 50°). This allows seagrass and weeds to slide off the fin rather than snagging, which would otherwise cause a "drag brake" or a catapult.

• Low Draft: Because the fin is angled back, it doesn't poke as deep into the water. A 26 cm weed fin often has the surface area and power of a 36 cm standard fin, allowing you to sail in much shallower "holes" or over sandbars.

• Large Base/Fine Tip: The shape is wide at the board connection to provide the "grip" needed for upwind sailing, but it tapers to a thinner tip to allow for speed and a bit of flex.

2. Vinylester Construction

• The "Sweet Spot" Material: Vinylester is stiffer than plastic but more flexible than G10.

• Shock Absorption: It has a specific "tip flex" that bleeds off excess pressure. This makes the fin very forgiving; if you push too hard, it flexes rather than instantly "spinning out" (sliding sideways).

• Repairability: Like the Freeride version, if you hit a rock or grind it on the sand, you can easily file and sand the Vinylester back to a smooth edge.

3. Technical Specifications

4. Comparison: Vinylester vs. G10 Weed Fins

• Vinylester (This model): Best for recreational sailors and "bump and jump" conditions. It’s more comfortable in choppy water because the flex absorbs the bumps. It is also the more budget-friendly option (usually under €100).

• G10: Stiffer and faster. If you are a heavy rider or a speed enthusiast who wants to "step on" the fin with maximum force, G10 is the better (though more expensive) choice.

Pro Tip: The "Depth" Rule

When switching to a weed fin, don't buy the same length as your straight fin.

• If you usually use a 36 cm Freeride fin, you should look for a 26 cm or 28 cm Weed fin.

• The extra surface area created by the rake compensates for the loss in depth.
