Well, we gave the kayanoe some stabality tests in the bath tub. For weight I used a large can of spegetty sause. Stabability seemed to increase with a slight tip but standing on the seat makes it a bit top heavy.

As for speed,  Increadable!!!!   Went from one end of the tub to the other in .04sec

If the full size modle preformes this good, I'll be tickeled pink
