My 30 ft custom MORC racer (also not a bad IMS boat) is
equipped with the Ockam System (same system as some of the America's Cup
boats have), including a built in VPP that I display all the time when
racing. Doing mostly windward leeward courses we live or die by the
target speed that is derived from my custom VPP, very similar to the IMS
polars. The target speed display is constantly updated by the system,
so even minute changes in wind speed is reflected within seconds, and we
immediately adjust what is necessary to maintain our targets..

I have a Signet SmartPac system on my boat that does the same thing. Problem
is the performance module that provides this feature comes with a chip
preprogramed for a New York 36. Since we sail an Express 30 and I refuse to
spend $450 for a custom chip we can never "catch up" We keep trying though.
LOL.
