Abstract
A surfing trainer apparatus comprises a board and a generally hemispherical fulcrum with the fulcrum attached to the lower surface of the board at the fulcrum's diametrical plane. The fulcrum is made of non-resilient material and has second planar surface distal to its diametrical plane and parallel to the lower surface of the board providing both a simulated point of limited stability as well as simulated instability in both pitch and roll.

A surfing trainer apparatus comprising:
- a board having a width and an upper and lower surface;
- a generally hemispherical fulcrum, said fulcrum affixed to said lower surface of said board at said fulcrum's diametrical plane;
- said fulcrum further comprising a hollow upper part and a solid lower part, said hollow upper part comprising said diametrical plane and a planar wall distal to said diametrical plane, said lower part comprising a second planar wall removably connected to said hollow upper part planar wall and a bearing planar surface distal to said second planar wall and distal to said diametrical plane.
A surfing trainer apparatus comprising
- a board having a width and an upper and lower surface;
- a generally hemispherical fulcrum, said fulcrum having a first and second part;
- said first part comprising an annular lip extending outward from the diametrical plane of said generally hemispherical fulcrum and said first part further comprising a planar wall distal to said diametrical plane;
- said second part comprising a planar wall corresponding to said planar wall of said first part and said second part further comprising a bearing planar surface distal to said planar wall of said second part;
- wherein said planar wall of the second part is affixed to said planar wall of the first part and wherein said annular lip of said first part is affixed to the lower surface of said board.
