It helps to reduce the amount of air in the tunnel and speed up the flow of air under the boat. If low enough they can actually have an effect on the water spray inside the tunnel and for this reason the Mutt boats have the corners nice and sharp at the rear similar to a sponson. Also best to check on dimensional allowances in the rulebook as I believe IMPBA and NAMBA are different. There are alot of theories in this area and I'm sure others will chime in....Mark Anderson, Phil Thomas, Geraghty to name a few have tested alot of different designs....
