County Line.jpg
 
 

Designed for County Line.

Located in Solromar, Ventura County. The go-to beach break when surf is good / mediocre. Mainly rights, though some good lefts occasionally come in. Fairly glassy at all times by outside kelp beds. Hollow and punchy waves good for short boarding. Hanging out on the inside, catching tons of waves, but important to cut back in quick not getting to close to the shore. The ideal board would be short and fast and loose. Medium volume to ease paddling but not too thick to get under the waves. The overall vibe is fun, fast, and energetic.

 
 
 

Subsonic was designed and hand-shaped by Ofir Atia. Intended to increase performance while surfing at County Line Beach. All key design decisions were strategically based off of location characteristics and personal experiences.

Rocker

 

The bottom curve of the board from the nose to the tail is called rocker. It is the curvature of the surfboard that allows your nose to stay above the water when dropping in steep waves. Because the Subsonic is such a short board at 5'2", it was essential to keep as much foam in the water to float the surfer. But also be able to drop into a steep face when necessary. For this reason, the Subsonic was designed with a medium to flat rocker.

Bottom Contours

 

The bottom contour of the surfboard is designed to channel water directing water flow through the board from nose to tail. The bottom contour effects the board's stability, maneuverability, and speed. The Subsonic has a flat to deep single concave.  The flat allows the board to be quick, and loose while paddling yet extremely fast and responsive when speed increases. That single concave contains the water flow compressing the water and squeezes it out towards the tail of the board.

Subsonic-Fins.JPG

Fins

 

Surfboard fins influence the mobility, stability, and the overall feel of a surfboard. They allow a board to be controlled in the water in a way that would not be possible without them. They help to maintain speed and control while cutting through the water. The board rides the way it was designed but by swapping out the fins it completely changed the way the board rides. In the above graphic you can see the three various designs.

Retro Keel

 

The retro keel is slightly shorter and has a higher degree of rake providing the most drive and stability of the three. The keel is harder to pivot with but accelerates down the line and calls for long drawn out turns. These are single foiled to compliment the bottom contour water flow.

The Hybrid

A blend of the Classic twin and Retro Keel, offering a balance between the two extremes. Keeping the height of the Classic twin but adding more rake and surface area to create more drive, stability, and control. The fin foils are single foiled to compliment the bottom contour.

Classic Twin

This larger set of twin fins was designed with extra height to give it more hold and stability. The upright fin template has less fin rake making it easier to pivot on turns. The thinner tips a the end give it more flexibility for pumping. The fin foil is 50/50 double allowing the board to lift with speed

Process

The manual labor required to pull this off was rigorous, but at the same time therapy for any maker. Understanding the end goal was not just an appearance model but a functional product fueled my passion and creativity.

 
 

I am currently testing boards and documenting the process. More content coming soon!
