DYNAFIBER URETHAN MAST BASE EU

The Dynafiber Urethan Mast Base EU is a high-quality, professional-grade mast foot designed for durability and a direct sailing feel. While Streamlined is known for its all-metal construction, Dynafiber offers a robust alternative that is very popular in the European market.

Here is the breakdown of its features and specifications:

1. The Urethan Tendon Joint

Unlike rubber "Boge" joints, this model uses a High-Density Urethane Tendon.

• Performance: The tendon is stiff, providing a very direct transfer of power from the sail to the board. This is the preferred choice for Slalom, Freerace, and Wave sailors who want precise control.
• Direct Feel: There is zero "play" or lag in the movement, making the rig feel like an extension of the board.

2. "Strong Base" Construction

The "EU" version refers to the Euro Pin (Universal Pin) connection system.

• Monoblock Top: The stainless steel pin and the top of the joint are often manufactured as a single piece (monoblock). This eliminates the risk of a threaded pin unscrewing or snapping under high lateral loads.
• Low Profile: The base is designed to sit very low on the deck. This lowers your center of gravity and "closes the gap" between the sail and the board for better aerodynamics.
• Four-Finger Grip: The plate features an ergonomic shape (often with four finger recesses) that makes it easy to tighten or loosen the base onto your board's mast track without needing tools.

4. Why choose Dynafiber Urethan?

• Reliability: It is known for its "Strong Base" reputation—it’s a workhorse that can handle the high downhaul tensions of modern race sails.
• Ease of Use: The Euro Pin system is the quickest way to attach your rig; you just push it in until it clicks.
• Maintenance: The tendon is easy to inspect. You can clearly see any cracks forming around the bolt holes, signaling it's time for a replacement (usually every 1–2 seasons).
