A beautiful, light boat. I have the fiberglass lay up with deep teal deck, purple seam line, white hull. A joy to paddle with little wind. Weathercocks badly in a following wind. Perhaps could benefit from a skeg or fixed rudder. Great secondary stability, nice low deck.
At 5'2" and 110lbs., the Tschaika fit me with just a bit of adaptation. I drilled holes to move the seat forward about 2", and then could reach the foot pedals. Moving the seat up also allows me to lock in to the non-adjustable thigh hooks. Now I am really "at one" with the boat, and love it.
