    Could also try flexsppon web site masses of info there.
    A concept I have been kicking around for some years but not got off the ground is a velo or edge spoon bottom and insted of the usual foam and fibreglass upper having an inflatable collar to make up the upper shape of the board as I see one of the major tern offs of a sppon is the 8-10 lbs of zero bouancy of the spoon great for duck dive etc but the weight and loss of flex must be an issue.

    Not so sure it is an issue Stu. You don't really notice the weight when riding and I think rigidity up front is part of the functionality.

    People make a big deal about the weight of boards but forget that their then sticking their own fat arses on top! Very Happy

    Update...update....update....

    Post  ULTIMATS on Sun Apr 08, 2012 2:36 pm

    Been a great summer here, instead of shaping Ive been getting down on the sand with da crew, just letting my mojo draw the ladies in....



    but I did do a lot with the surfcraft design.

    I thought about how to get the essential of what I was building, I wanted a free forming hull with a perimeter rail.
    But I was using 2 sides ( deck and hull) and inflating the middle.
    Could I do it with just one skin / one surface and the perimeter. And do away with the inflatable construction, valves etc..?
    It would look like a drum skin, where the material is supported by the frame but the tension can be altered, like a drum skin.

    So I whipped up an EPS frame...



    And then I thought , "I better start small and test the theory"....
    So I whipped up a handplane instead.









    And put a clear vinyl hull on it.







    Kid tested.



    And the damn thing works.
    The vinyl starts out flat when you take off but when you hit a steep section the vinyl stretches and forms a concave and gives more grip.
    Very happy with it !!
    But thats not all...

    You didnt even notice I'd lost weight !
    Anyway, the vinyl is taped with a bit of tension before its glassed on so it has more resistance than a mat bottom. Even a bit of bounce to it.



    No, I didnt notice it being even slightly slower than a solid wood or fibreglass handplane.
    But you do notice the change and effect of the hull when it forms into the concave, it loses its slide and the inside rail grabs on.
    The vinyl comes in different thicknesses and its a professional marine product usually used for making clear weatherscreens on yachts and powerboats. $22 a metre X 1.8m wide..cheap.
    I'd glassed it on by perforating the perimeter



    and after a week it was starting to peel off,



    Pity because it looks way cool and when theres a break between the sets you can watch the fish underneath you thru the hull.

    So I ground the vinyl off



    And later I was hosing the kids trampoline off I noticed the stream of water ricocheting off the mesh. And I thought " I wonder if that would work too"
    So I bought some trampoline-mesh from the same marine supply place where I got the vinyl from...



    Taped and glassed it on.









    And gave IT a go....

    And it works too, its bizarre ! But I think I know why...

    Given that this mesh isnt flimsy flyscreen , its a professional trampoline mesh used for catamarans and the like, probably 80% mesh to 20% air so its almost a solid sheet anyway.








    Due to the tight weave the mesh provides moderate resistance to water when the flow is at right angle to the surface ..




    but as the angle of the flow gets flatter the water starts to 'see' the mesh as a solid piece and very little water gets thru.







    Initially I thought..Nah this aint gonna work at all, but it does.

    When you take off its fast and the mesh forms a concave just like the vinyl does.

    I went a bit further and put a central beam in ...





    and now it makes a single concave in the front and a double concave in the tail that gives a lot more grip that a single concave.





    One advantage of the 'Dynamic Hull' is that the water pressure creates the perfect shape for the situation.

    But theres more !!...

    I think you're on to something here mate. Bit of a shark skin effect too!

    What's the "more"?

    Yeah G, I think theres some distance in the theory, theres a lot of possibilities...
    Could be the Sharkskin effect, I did think that it wouldnt work AT ALL, but still I bought the material, built it and tried it and now I know it does work.
    I wasnt really sure where to go from here but i figured I needed to make another handplane before I went Full-Scale and made a prone craft.
    So heres the next handplane.....

    Start with a ply base, its a minimalist design to see the effect of reducing the solid frame as far as I can and maximising the mesh area....



    Build it up with layers of glass for strength..



    And the plan is to put a skinny hand support to bridge the sides. And give it the mesh hull of course.



    THATS where Im up to now.

    Thanks G,
    funny how its gone from a mat...
    to a hard deck inflatable...
    to a frame with a semi permeable single skin.
    After I do this next minimalist handplane I'll do a bodyboard with the same mesh for the hull and deck.

    Im calling it The Flying Vee,

    Heres the frame...



    And the mesh.

    Started on the hand bridge today.
    I drew out a paper template of the bridge...



    And glassed over it with 6 layers.



    Ive got it laying over a curved piece of ply so it fits into the palm of your hand.



    Looks crude but it'll come good now Ive got a plan in my head.
