PHRF Chesapeake Bay
Our deep draft 1986 Hunter 28.5 rates 174 non spinnaker on Chesapeake Bay with a 155% Genoa, no roller furler and a folding prop. Shoal draft may add 6 seconds per mile; roller furling may add 6 seconds, and some areas may give you a credit for a fixed prop. Don't expect that 190 and upwards rating; that's probably for the newer 28 which has a different rig and keel.There's a web site for the 28.5's with several racers, including some in the Great Lakes area:http://groups.yahoo.com/group/huntertwentyeightfive/
