Convex surfboard bottom design that bisects the rear and/or middle area of the board into two longitudinal panels; introduced by Australian boardmaker Bob McTavish in 1967. Vee makes turning easier, as the board wants to lean over on one panel or the other. Flat- or concave-bottom boards, however, are faster.

While vee itself is a design feature, the "vee-bottom board" refers to a design McTavish came up with in 1967: a wide-backed, thick-tailed "plastic machine" that opened up the late-'60s shortboard revolution.

"Spiral vee," popular in the '70s, is a slightly cone-shaped version of vee, with the point built into the area just below the surfer's back foot. "Reverse vee," invented in the early '90s, places an inversion, or concavity, in the middle section of the board, beneath the rider's front foot. Standard vee, as of 2013, was often so slight as to be nearly undetectable.
