Pyranha Shiva used whitewater kayak

The Shiva has a rounded hull, soft aft bow section, high bow spring and plenty of volume in the bow and stern.

These features give you a softer landing on big falls, rear propulsion when you want it, fantastic boofability and surfacing ability. A rounded and tall deck with a high center of volume offsets a low center of gravity for easy rolling.

If you run big drops and push harder lines, the Shiva is what you're looking for.
