Abstract:
The power surfer is a simple device that is used to convert most of the wind driven sailboards or windsurfers being produced these days into a surfboard which can easily be pulled behind a boat or other type of watercraft.

BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to surfboards which can easily be pulled behind a boat or other type of watercraft, and more particularly to a device that can be used to convert a wind driven sailboard or windsurfer into such a surfboard. 
     2. Description of the Prior Art 
     Most of today&#39;s windsurfers and sailboards, as shown in FIGS. 1 and 2, item 1, have a &#34;track&#34; that supports and allows for any adjustments to the mast of the sail assembly. These tracks are usually comprised of aluminum or plastic and mount into the windsurfer or sailboard itself. Although tracks made from these types of materials are strong enough to handle the weight of the mast and sail assembly, they are not durable enough to withstand the continuous force exerted when the sailboard or windsurfer is being pulled. 
     SUMMARY OF THE INVENTION 
     Therefore, an object of this invention is to provide a simple device that can be used to convert a wind driven sailboard or windsurfer into a surfboard which can easily be pulled behind a boat or other type of watercraft. 
     The device according to a preferred embodiment of the invention comprises an adapter for releasably connecting a water buoyant board to a tow rope and attached handle, the board having a track or recess, the adapter comprising: 
     (a) a mounting base for releasably engaging the track recess; 
     (b) a holder connected to the base, the holder sized to receive at least a portion of the handle, the holder having a substantially closed end, an open end and a rope slot extending from the open end, the holder sized to receive the handle such that the tow rope passes through the rope slot; and 
     (c) an end cap for engaging the open end of the holder to enclose the portion of the handle intermediate of the closed end and the end cap, such that the tow rope passes through the rope slot.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As shown in FIGS. 1 and 2, the power surfer consists of a &#34;mounting base&#34; assembly 4 along with a &#34;main body&#34; assembly 2. As you can see from FIG. 1, the main body section of the power surfer is constructed so that the &#34;D&#34; or &#34;T&#34; handle of a standard water skiing rope 3 can easily be inserted into it. This unique design means that you do not have to make or buy a seperate or special tow rope just for the power surfer. Also, it should be noted that the rope coming back from the watercraft attaches directly to the sailboard or windsurfer (through the power surfer) to give the user a truer feeling of surfing rather than having to hold onto the tow rope or else a sail assembly. The power surfer comes with its own mounting base assembly 4 which makes use of the same track mounting screws to fasten it to the sailboard or windsurfer 1 once the track has been removed. FIG. 2 shows the mounting base assembly 4 of the power surfer along with the track mounting screws 5. The mounting base assembly 4 is made up of a piece of metal flat stock about one foot in length, 3/4 of an inch in width and about 1/4 of an inch thick. A one inch long coupling nut is placed on end onto the metal flat stock and welded so that the open end of the nut can accept the connecting bolt 9 of the main body assembly. Two triangle shaped metal &#34;gussets&#34; are then welded to both the coupling nut and the metel flat stock for added strength and support. 
     FIG. 2 also shows the construction of the main body assembly of the power surfer. Looking from top to bottom at the main body assembly&#39;s major components, you see that it consists of an upper cap 6, a slotted tube-shaped body 8 and a lower cap 11. The upper cap 6 is an unthreaded durable plastic (PVC) pipe cap with the purpose of holding the tow rope inside of the slotted tube-shaped body 8. Because the pipe cap does not float in water, one end of a short length of thin cable is attached to the cap and the other end of the cable uses a metal clip 7 to connect to the tow rope. Like the upper cap, the slotted tube-shaped body is also constructed of durable PVC plastic of the same pipe size as the cap. The tube-shaped body is threaded at its bottom so that it can be screwed into or out of the lower cap 11 of the power surfer. The lower cap is just like the upper cap except that the lower cap is threaded. A hole is drilled in the bottom of the lower cap to accomodate the connecting bolt 9 which is inserted and tightened into the connecting nut of the mounting base assembly. Finally, a locking nut 12 is placed on the connecting bolt and tightened down onto, the top of the coupling nut of the mounting base assembly to lock the two assemblies of the power surfer together.
