Two pairs of resilient body blocks are provided with each pair of blocks interconnected by an elongated, flexible, stretchable and elastic tether member extending and connected therebetween. The blocks include adjacent sides having grooves formed therein opening laterally outwardly of the blocks toward each other. The grooves parallel each other and are open ended and embracingly receive opposite longitudinal side edges of a sail or surf board therein with the pairs of blocks spaced longitudinally of the board and the tether members thereof functioning to clamp the board between the pairs of blocks. The side edges of the grooves are spaced inwardly of the corresponding side surfaces of the blocks and the board, with the blocks supported therefrom, may be disposed in horizontal position atop a vehicle with the undersides of the blocks engaging the vehicle top and the blocks supporting the board in spaced relation relative to the vehicle top. Suitable tie down straps may be secured between opposite sides of the vehicle top and over the board in order to maintain the board in position on the vehicle top. Further, the blocks spaced along one side edge of the board may be used to support the board in edge upstanding position from a suitable horizontal support surface when the board is being stored.
