With a borrowed 15hp 2 stroke Yamaha on the back, she hit a top speed of 24.8 knots. I must admit it was a little bit skittish at that speed and I wouldn't want to sustain that speed for long periods. With another person onboard she was very controlled even at full throttle when she reached 21.5 knots. With 4 adults and a 2 year old we still managed 19.5 knots! Slides a bit in fast turns but that is to be expected from a fairly flat bottomed hull, throttling back a little is all that is needed.
