Boats track super well. Very, very maneuverable...fast. Punch through waves. Full boats drain quickly. Comfortable height above water and dimensions/geometry make for efficient and ergonomic paddle strokes. (I use a 230cm paddle)
Love the seat...I was a bit skeptical, but super comfortable!
Picked these up for the kids to track along during family raft trips, but finding myself testing them out on the spring runoff around here...
Additionally, I know of the owner of the Zoik boats and I do not think they have anything to do with Star (they may be made in the same factory? as 60% of all PVC inflatables are made there...so I have been told)...I believe this is a standalone, new independent company.
