I'm sure there is some wet foam. In theory, would more sandbags/rockbags/ballast under the front closed bow help the boat plane out? I've wakeboarded for many years and had a phone app to track the speedometer. We were going 22mph and the front of the boat was very high up in the air it seemed like. I need a HUGE wake in order to do flips/get massive air, so I do plan on adding tons of weigh all throughout the boat, but need enough weight maybe in the front in order for it to plane out at 20-24mph.
