Infinity B-Line – High-Performance Competition Surf SUP

Explosive. Precise. Built for aggressive, pro-level surfing.

The Infinity B-Line is the most progressive, competition-driven surf SUP in the Infinity lineup. Designed for advanced riders who want maximum speed, razor-sharp turns and fast, controlled rail-to-rail transitions, this board is built to attack waves with intensity.

If you want a board that feels like a shortboard under your feet but delivers SUP-level paddling power into every section, the B-Line is it.

What the B-Line Feels Like

The B-Line takes the ultra-snappy, high-performance DNA of the BLURR and blends it with the added stability found in the RNB.
The result?
A board that can be pushed harder, hits sections faster and offers explosive redirecting off the bottom — without feeling twitchy or unstable.

This is a board for riders who want zero compromise in performance.

Design Features

Sharp, Linear Outline

A slightly wider nose than the BLURR helps with stability when paddling and taking late drops, but the outline still pulls into a pointed shape for tight pocket surfing.
A linear midsection increases stability without slowing the board down.

Performance Wing Tail

The outline breaks at the fins with a defined wing, giving:

• Quicker pivot off the bottom

• Faster release through top turns

• More responsiveness in steep sections

It turns exactly when and where you want it to.

Fast Front-End Rocker

The front rocker is more relaxed than on the BLURR, giving the B-Line:

• Exceptional speed down the line

• Easy acceleration

• Better flow in weaker or longer waves

Tail Flip + Speed Channel

A more aggressive tail rocker and speed channel release water cleanly, giving:

• Faster snaps

• Instant response

• Extra grip until you choose to break free

This is a board that thrives in critical, high-performance surfing.
