We need some down-wind speed for our 1993 H27(OB). We did great in our first season of racing (won the 1998 Claytor Lake Cup) but in a multi-class fleet corrected by the Portsmith rule, we are getting trashed by the centerboarders when ever there is a big down-wind leg. They set their spinnakers and fly away. Should we just rig a gennaker on the regular jib halyard, or spend the big bucks on a mast-head spinnaker set-up? Broad-reaching back and forth with our 150 is just not cutting it. Since we can't pull up a board to reduce drag, we need more power. But HOW?
