Dynafiber Urethan Mast Base EU
The Dynafiber Urethan Mast Base EU is a professional, high-performance mast base designed to offer maximum strength and a direct feel between sail and board.
Thanks to its high-density urethane joint and Euro Pin standard, it is a reliable and quick-to-use solution for slalom, freerace, and wave windsurfers.
Key Features
High-Density Urethane Joint
- High-density urethane joint that replaces traditional "Boge" type rubber joints.
- Very direct power transmission from sail to board, ideal for slalom, freerace, and wave.
- Immediate and play-free feel: the rig becomes a natural extension of the board.
"Strong Base" Construction
- EU version with Euro Pin (Universal Pin) connection, compatible with almost all modern extensions.
- Monobloc top with stainless steel pin and joint head made in one piece to reduce the risk of loosening or breakage.
- Low-profile design to lower the center of gravity and reduce the gap between sail and board, improving aerodynamics and control.
- Ergonomic "four-finger" plate for easy tightening and loosening on the board's mast track, without tools.
