Hi.  The props worked great.  After repairing the port prop the second time (ouch!) we once again have no discernible vibration from the running gear.  This has not been the case in the past couple of years so we are very pleased with the PROP-SCAN based technology.  I think we can safely say that the boat has never run so smoothly and is most likely quicker, but this last is hard to pin down as we did some hull modifications at the same time that you trued the props.  Nevertheless, we are getting 18-19 knots at 1800 turns which is good performance on this boat as she is presently configured.  She is roughly 55X17 feet and displacing 30 tons or so.  The boat is running a little heavy due to our having installed a flying bridge, mast, A-frame, oceanographic winch and swim step since she came into our possession.
