Patent ID: 7367153

Claim:
A planar board comprising in combination: two boards, each of said two boards having an inside surface, an outside surface, a near end, a distal end, a top surface, a bottom edge, and a center portion, each of said two boards having at least one angled opening from the outside surface to the inside surface, the inside surface of each of said two boards being concave and the outside surface of each of said two boards being convex, the near end of each of said two boards being an angled water displacement surface; one of said two boards having three cavities in the top surface, two of said three cavities in said one of said two boards laying adjacent to each other and located near the near end, and a third cavity of said three cavities being located distant from the two cavities and near the center portion thereof; the other of said two boards having three cavities in the top surface, two of said three cavities in the other of said two boards laying adjacent to each other and located near the distal end, and a third cavity of said three cavities being located distant from the two cavities and near the center portion thereof; two cross support members, each of said two cross support members having two angled ends, each of said two cross support members positioned such that they cross from the one of said two boards to the other of said two boards, wherein one of said two angled ends of one of said two cross support members inserts into the third cavity near the center portion of the one of said two boards, and the opposite end of said two angled ends inserts into one of the two cavities that is nearest to the distal end in the other of said two boards, and the other of said two cross support members has one of said two angled ends inserted into one of the two cavities nearest the near end of the one of said two boards and the opposite end of said two angled ends is inserted into the third cavity near the center portion of the other of said two boards; a diagonal cross support member, said diagonal cross support member having two angled ends, one of said two angled ends is inserted into the other of the two cavities located near the near end in the one of said two boards and the opposite end of said two angle ends is detachedly inserted into the other of the two cavities located near the distal end in the other of said two boards; the one of said two boards having an anchor point situated near the top surface and being centered between the two cross support members.
