a stringerless foam;
a generally planar deck portion,
a generally planar bottom portion,
a nose
a tail;
a left rail and a right rail each outlining edges of the stringerless surfboard from the tail to the nose; and
a set of channels formed on the deck further comprising a pair of adjacent, axially extending elongated concave grooves that meet at their endpoints to form a rigid elongated convex center,
wherein the set of channels comprises a left set of channels laterally positioned on the deck along the length of the left rail and conforming to a curvature of the left rail, and a right set of channels laterally positioned on the deck along the length of the right rail and conforming to a curvature of the right rail,
wherein the left set of channels and the right set of channels face and curve in toward each other.
