Sharp Eye SB-T Surfboard Model Description: The SB-T (Tipton Model) was first created for the tall, experienced surfer. It has the most extreme rocker of all shortboards, and a very distinct forward volume. The results are incredible. The SB-T is fast, and feels solid underfoot. We also tried it in smaller versions for some of our team riders, and everyone was stoked. Wave Size: Medium to Overhead. Skill Level: Intermediate to Pro.
