Bumper Boats and Boat Tag will be retired and removed later this year to make space for Knoebels' new-for-2015 roller coaster, Knoebels Impulse.
The Zierer coaster will have a 98-foot-tall lift followed by a 90-degree free-fall first drop. Three eight-rider vehicles will cover 1,985 feet of track at speeds up to 56 mph, maneuvering through a cobra roll, loop, Immelmann, helix and airtime-filled hills.
Knoebels Impulse riders will be seated in two rows of four, facing forward, with the back row seats elevated above the front row seats for back-seat visuals during the course.
Knoebels Impulse will be the sixth roller coaster in the park, joining Phoenix, Twister, Kozmo's Kurves, Black Diamond and Flying Turns.
