    Looking for some details on the mast/ main beam for the Simpson Slipstream 50 design.
    I rebuilt one of these in the early nineties in Brisbane Australia and can't remember the details.
    Must be getting old!
    I did have the design sheets but think long gone.
    I do remember that it was ply/ timber truss design and very simple and strong.
