OUR MOST PERFORMANCE-DRIVEN UNIVERSAL SHAPE, BUILT WITH THE MOST ADVANCED CONSTRUCTION. PROUDLY MADE AT H.O.M.E. IN THE USA.

A shape that refuses to be boxed in. The M50 combines the best of skim and surf worlds with a fast, responsive ride that adapts to any style. New for this year: Speedwalls for added strength and glide, a quad fin setup, an updated tail outline for more drive, and slightly more rocker for powerful turns.

Built using eco-friendly Dark Matter construction, the M50 is ready to match your energy, whether you’re throwing buckets or landing 3-shuvs. Comes with our unique Cheese Grater fins — tight or loose depending on which side you mount them. A fast, responsive board that excels in any condition. The ultimate performance-driven universal shape made with the most advanced construction. Combine this technology with a shape that adapts to your riding — Model 50 = M50.

Our 50th model developed in the Ronix era. Whether you prefer skim-style shapes, longboards, thick or thin, fast, loose, or locked-in designs — this board covers the widest spectrum of styles. M50 celebrates the perfect blend of past, present, and future boards in a single all-encompassing quiver. Enjoy the new 2025 construction with less swing weight, higher airs, and more powerful cutbacks. Flagship surfers proudly made in the USA — welcome to the Herb O’Brien Manufacturing Experience.

BUTTON FIN — THE SIMPLE NEW FIN SYSTEM

This patent-pending design, developed over 5 years, is now available on the M50.
Typically, riders must apply force to release a fin. With the Button system, the energy comes from the internal mechanism — effortlessly release fins with a simple press.
Fins float, and carbon epoxy construction makes them our stiffest, most responsive setup.

Setup:

1. Align fins with the fin box.

2. Press evenly until locked.

3. Ride!

Removal:

1. Press the button moderately until it bottoms out.

2. Pull the fin up while holding the button.

3. Insert a new fin and ride again.
