[QUOTE="Ebug, post: 431778, member: 11893"] You might take a look at venting your tunnel to release some of the suction it seems to be creating with the current attitude of the hull. Try a google search for "Vented Tunnel Hull" You will see what others have done. A creative person could rig up a temporary/test system using Ø1/2 PVC and a ball valve hanging over the transom turning under/into the tunnel with a 180 pointing the outlet towards the stern. Try to get that 180 outlet as far forward in the tunnel as you can and not have it stick out. The ball valve gets adjusted while under way to allow small amounts of air to enter the front of the tunnel to disrupt the suction. The folks I know with flats boats with vented tunnels get them adjusted the way they want and never adjust it again. Just a thought. Rob [/QUOTE]
