Abstract: A temporary mast support and storage structure for a detachable mast for a wind surfing board or the like having an attached sail and boom structure. The structure includes a first hollow, elongated cylindrical sleeve having a radially outwardly extending flange whereby the flange adapts the sleeve to be emplaced in sand or concrete and the flange being further adapted to be coupled with a vehicular mounted trailer hitch. A second hollow, elongated cylindrical sleeve having a radially outwardly extending flange is provided the radius of the cylinder of the second sleeve being lesser than the radius of the cylinder of the first sleeve such that the second sleeve fits within the first sleeve with the flange of the second sleeve overlying, at least in part the flange of the first sleeve.
