    Don’t be surprised if no one answers. SAW sponsons are part of the secret recipe racers are unlikely to share. I suggest you start with a JAE sponson and then test and modify. Try different widths and angles of attack till you are satisfied.

    Once you get to a certain speed SAW rigger sponsons and their booms become expendable items. I build 6 pairs of sponsons for new SAW boats these days as any crash it almost a guarantee a sponson and/or boom will break.

    I came up with a good system where I would design the sponson as a 2D profile similar to a JAE with my own angles. I would buy a 12"x48" sheet of foam and birch ply and make a large sandwhich panel. I would laser cut an acrylic router template and using T-pins to hold the template on the sandwhich panel using a trim bit I would cut as many sponsons as I could from a single sheet. The router template also had plunge holes where the boom tubes would go making it easy to have consistent boom placement. I would then glue on ride pads and bond in tubes for the boom.

    Later versions used a center rib in the sponson and laser cut wood frames. The routing was necessary to trim the foam to the sponsons. Notice how I also hollowed out the sponsons to keep them light.

    Randy Naylor at BBY Racing may be your man, I know he has built SAW boats for profit in the past.

    Tyler, I would never ask you to tell us all your secrets but is there an AOA range that's sensible for a sprint boat and an AOA range that's sensible for a SAW boat? haha And never the tween shall meet?

    Terry, they tend to be different and the width of the ride pad changes too.
