My Egrete rhine pusher tug is 28inches long and 10 inches wide, its powered by the equivalent to twin 600's with 6:1 gear reduction boxes, driving 50mm korts. It sails a treat, yes, ok so cant outrun a sports boat, but its not got the bows designed for that, afterall, they rely on the bows on the forward barge its pushing to cut the waves. perhaps if you made a barge and tried that, you may be better impressed with your springer then.
