Description
11'~2'7~39 This invention relates to a sailboard which consists of a stagless rig and a board body which is provided on its underside with drift-resisting means.
The previously known sailboards have different designs selected in accordance with the intended use of the sailboard.
For instance, sailboards for surfrising are relatively short and have a wide, raised prow. Their underside is flat. Such sailboard cannot well be used for sailsurfing on smooth water, particularly when the wlnd is light or gentle and has a strength below No. 4 on the Beaufort scale.
On the other hand, sailboards for use on inland waters, particularly in light or gentle winds, should be relatively long and their submerged portion should constitute a so-called displacement body.
For these reasons, a plurality of sailboards must be available to a sailsurfer who intends to use his sailboard on open waters and inland waters. This requirement is not desirable, for several obvious reasons.
The object underlying a prior application of the same inventor (German Offenlegungsschrift 27 53 Q31 published 31st May 1979) was to provide a sailboard which has universal usefulness. For this purpose it was proposed to provide a com-posite board body and to adjustably connect the fore or aft section to the adjoining section so that the fore or aft section can be used in at least two .,~
~ ~ ~zt7~
positions.
~ .xperiment3 have shown that such a sail-board i9 more,~ersatile -than the conventional sailboards but in various cases will not possess -the optimum sailing proper-ties of a specicll sai,lboard~
~ or t~is reason i-t is an object of the invention to provide a sailboard which has universal us,efulness and has optimum sailing properties in each case.
In a sailboard having a board body which has the minimum leng-th and a l`lat underside having good sliding properties, this is accomplished in that a sole member is provided, which positively interengages wi-th the underside o~ the body cmd is detachably connected to the latter and has suitably a convey underside. The body without the sole member constitutes a base board which can be descrîbed as an ideal sliding body. The assembly consisting of the body and a suitable sole member has such proper-ties that it can be described as an ideal displacement body.
~ ithin the scope of the invention7 a plurality of sole members having differen-t submerged por-tions may be associated with a single board body. Such a vari-able sailboard will constitute optimum equipment for a sailsurfer. The novel sail'board having a sole member repl~aces at least two conventional sailboards -md can be made at lower cost than such two sailboards.
It can also 'be more easily transported and requires a smaller space in s-torage~
'~ilithin the scope of the i.nvention, the sole member may have the same length as -the board.
body. In dependence on -the requirements, the sole mem'ber may ex-tend. beyond the fore and/or aft end of the board body. Alterna-tively1 the sole member may extend at one end beyond the fore or aft end of the board body whereas the other end of the sole member is dis-posed bet~een the fore and aft ends of -the boards body.
It has been found desirable to provide the sole member at the top with a recess for receiving at leas-t part of the board body.
In order to minimize the time required for an alteration Or -the sailboard, the sole member is suitably provided with vertical through openings for receiving the dri:~-t-resisting means provided on the board 'body. For the same reason, -the sole member may be connected to the board body at one end by hooking means. ~hat hooked end is suitably the fore end.
._ As has been stated hereinbefore, the underside of the sole member is suitably convex. If -the sole mem'ber extends beyond the aft end. of the board body, the sole member may be narrower than -the board bodyO
An illustrative embodiment of the invention will now be described more in detail with reference -to the accompanying drawings, in which Figure 1 is a side elevation showing a board body, ~ _ Z~99 L1`igure 2 is also a side elevation showing a sole m mber for the bo~-lrd body of 'Figure 1, ~ I'igure ~ is a top n'l~n -view showing the board 'body bvhich has beon joined to the sole member, L~'igure 4 ;s a transverse sec-tional view taken on line IV-IV in Figure 3, and L~iy;ure 5 is a side elevation showing the aft portion of the as<-,embly of l?igure 3 on a la:rger scaleO
,r,l sailboard consists of the board body 1 shown in Figure 1 and a stagless rig, ~,vi)ich is not shown because it is conven-tional. The board body carries drift-resistin~ means consisting of a center board 2 and a fin 3. ~he board body has onl,y the minimum length required and its underside is flat (see also Figure 4) so that it is well sui-ted for surfriding and for sailing at high wind velocities which result in a ruffled sur-face of the water or in waves.
In accordance with the invention the board body 1 is p,rovided with a sole member 4 (see particularly ~'igure 2), which has been applied to the underside of the ~oard body and positively interengages -therewith.
As is shown in Figure 4, the underside of -the sole member is convexO By -the provision of such sole member, the properties oE -the board body 1 are so changed that it is transformed from a sliding body to a displacement body. ~'he resulting sailboard is desirable for use on 3o inland waters and can 'be used par-ticularly at low wind veloci-ties.

The aft portion o r the s~le 4 iS raised so as~to be flush with the board body (see Figure 5~. Two tog~-,le joint tightners are provided for connecting the board bocly at i-ts'aft end to the sole member. The hook 8 of each tightener is secured to the aft end of the board body 1. The tightener lever 9 provided with the pivoted loop 10 is pivoted to the opposite portion of the sole member. To permit the use of a sole m.ember which is thin and light in weight, stiffening :ribs l-l, 12 are provided in this embodimentO
In the embodiment ~hown, the sole member is provided at its af-t end with a fin 13. The shape of the through opening 14 provided in the sole member 4 (Figure 2) for the fin 3 o:f'-the board body 1 will depend orl the nature of tha-t fin 3. The sole member 4 is also provicled with a through opening 15 for -the center board 2 (Figure 5).
