I probably should rephrase the word porpoise...too say "rides better" when weighted in the bow. Seems like when you have 5+ people in the back and no weight in the front a Super Sport/Air the bow tends to "bounce" more when hitting other wakes and waves. This is easily corrected by filling the front sac/tank.
Douglas, not sure how much it will change your boats wake, but it is worth a shot. Might just make it bigger and not round it over??
