Your boat is much lighter than the Ranger fiberglass boats and some of the aluminum boat are floored with plywood that makes them much heavier. The way the bottom is made has a lots to do with it also if yours is the totally flat bottom boat that doesn't have the V shape to cut the water up front in the water it will cause the boat to bounce more also. Adding weight up front will help but be careful as not to cause other problems with large waves as this would be the time to be safe just go home.
