PREDICTABLE AND STABLE, Built for Progression
New for 2019, the O’Brien Ratio has everything a pro rider needs, but is truly ideal for beginner to intermediate riders looking for a predictable 3-stage board with explosive pop off the wake. Designed with 4 molded fins as well as tracking channels, the Ratio provides a smooth ride with plenty of hold on the water. The variable beveled edge keeps the midsection of the board catch-free and tapers towards the tip and tail for added bite when edging. This easy to ride board is perfect for building fundamentals, improving confidence, and enhancing progression.

PROGRESSIVE ROCKER
Similar to our Continuous Rocker but with a more kicked up tip and tail, resulting in more vertical pop than a Continuous Rocker and more predictability than a 3-Stage.
DELTA BASE TECHNOLOGY
“Chevron” shaped channels molded into the tip and tail of the board reduce drag for? faster edging and a cleaner release off the wake.
FEATHER CORE
Feather Core reduces the board’s swing weight for more midair control, while? simultaneously maintaining its profile up the face of the wake for maximum pop.
6mm INSERTS
Industry standard 6mm inserts. So if you happen to loose your bolts, borrow some? from a friend or make a quick trip to any hardware store.
MOLDED IN FINS
Quad molded in fins.
