Skied behind it, a TXi, 2001 Response and 99 Sportster all summer.
Sanger had the Scorpion motor. Lots of grunt and near 50 mph top end.
Does take a bit wider arc on turn around, won't slide the back end, but not unmanageable. If still built with wood they went to all treated, non rotting wood in 1994. Very solid and good riding boat through rough water.
15-28 off wakes are firm and the ankles/knees take a hit. Remember the first time skiing behind it coming off the TXi at 28 off, thought my ski was going to break from the impact. Went back to 15 off where it was a bit softer but still harder than flatter bottom comp boats.
Needless to say we all, even the Sanger owner, prefer skiing and ski better behind one of the Malibus. Great barefooting wakes though. Don't think they ever stopped producing this model. Been on their website all the years I remember.
