Out on the water, the 540 is a spirited performer. While she posted a wide-open-throttle speed of 40.5 knots, at 2,200 rpm she clipped right along at a comfortable 37 knots. And just as impressive is her 31-knot turn of speed at 1,800 rpm. Of particular note is the way she answered the helm with almost instantaneous response to either port or starboard turns. Whether hard-over maneuvering or countering through S-curves, she came right back to straight and true tracking. And while my test day saw flat-calm conditions, I did manage to find a rather large vessel throwing a more than substantial wake, and, making a beeline for it, I put her right into it, noting the way she shouldered through with no slamming or pounding.
