Sheave Ø 30 + 20 mm Max

The new Vulcan anchor is Rocna’s first major design development since the launch of the highly successful and acclaimed Rocna anchor itself

The weight of this high-strength block is only a few ounces

Make sure there are no sharp points in your boat that would snag or puncture the buoyancy bags

This development permits a larger fluke surface area than competing designs which rely on simple dead weight
