what can i say, summer is almost done and i was able to stress-test the 2017 Kaku Wahoo 10.5' kayak at the Grand River, . This kayak is a River Monster. it handled the rocks & water with full force very well and its unbelievably stable. The back-park is precise and smooth. Love how the black plastic bottom hull at the back is separated from the main hull, ideal for back parkers such as myself. i checked the front hull after the river run and found no dents and hardly any scratch. It does have its battle scars but that's about it. Kaku Wahoo is highly recommended.!!
