4.6" Twin Keels – Futures compatible melon Pro Glass (2 fins)

Melon Pro Glass keel fins for fast, flowing twin-fin surfing with drive, hold and smooth control.

These surfboard fins combine a wide-base keel template with solid Pro Glass construction for speed, projection and dependable hold.

Choose these keel fins when you want:

• Fast down-the-line performance with sustained drive

• Smooth, drawn-out turns and predictable rail engagement

• A classic keel-fin feel for a retro fish or traditional twin-fin surfboard

• Solid fibreglass fins with controlled, consistent flex

• A matched pair of Futures-compatible Eveley fins

Best suited to: Retro fish boards and traditional twin-fin surfboards.

Recommended conditions: Small to medium clean waves where glide, trim speed and flowing turns are the priority.

Performance feel: Fast, stable and drive-focused. The long base and raked outline favour smooth carving arcs rather than tight, upright pivoting.

Compatibility: Fits surfboards with Futures-compatible side fin boxes. These fins do not fit FCS or FCS II fin systems.
