example 1
[0085] refer to figure 1 , a cross-sectional view of a prior art surfboard 1 is shown with the surfboard 1 having a top 1A, a bottom 1B and sides 1C and 1D. The panel 1 comprises a so-called "slab" part comprising two foam sides 2, 3 made of polyurethane (PU) foam and a stringer 4 usually made of light wood such as balsa. To produce the finished surfboard 1 , the stringers 4 and the foam sides 2 , 3 are clad in an outer layer generally indicated by the line 5 . The layer 5 comprises a mixture of one or more fiberglass sheets 6, generally more such mixtures are present on the top or deck 1A of the panel 1 than on the bottom 1B of the panel 1 for structural reasons. One or more fiberglass sheets 6 are mixed with a hardening resin 7 which hardens and the glass fibers 6 are held within the resin 7 . The described prior art panel 1 design has been used for many years, but the design is far from perfect and represents a favorable compromise between weight and ease of manufacture, ...
example 2
[0087] figure 2 and image 3 A first embodiment of a surfboard 10 based on the new design described herein is shown, generally indicated by arrow 10 .
[0088] figure 2 A cross-sectional view of the board 10 using the fleece sheet 60 in the resin 70 is shown. As shown, the internal features of the slab of panel 10 can remain the same as in prior art designs with stringers 40 and foam sides 2, 3, and the basic layering principles in the embodiment involving plush also remain the same. remain similar, i.e. the plush layer 60 remains in the same figure 1 A similar position is shown for the fiberglass layer 6 . Typically multiple layers of fleece 60 may be added to the area of the deck 10A for added strength, however multiple layers may also be added to the underside 10B. According to the experience of the inventors, it is sufficient to use a single layer 60 on the bottom 10B and a double (two) layer 60 structure on the top or level 10A of the board 10 .

[0093] refer to Figure 4 , which shows a second embodiment, in this example showing an outer layer 120 with a fleece sheet 140 for use in a kayak 100 design. Detail AA shows a close-up of a possible kayak wall design. It is relatively uncommon to use a mix of fiberglass and resin in a kayak or rowboat because the combination doesn't have the strength these products require. Kayaks and rowboats use a wide range of materials, with more robust designs made of plastic, while more lightweight and high-end designs can be made of fiberglass or even carbon fiber. The tradeoff is a trade-off between weight and strength, for example a sea kayak needs considerable strength, so is made of plastic and is heavier. Racing kayaks and wakeboards are narrow and lightweight, so fiberglass or carbon fiber are acceptable materials to use, and strength is less of a concern. It will be appreciated that the aforementioned layers of plush sheet material and resin may be used as a replacement for f...
