J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Harken spinnaker car track to deck

In 1998 I did exactly what you propose. Replaced the existing track with a 10-ft section of Harken ball bearing track extending down to just above the deck. I figured (unscientifically) that the track added enough stiffness to make up for the extra holes. Never had any problems with the track or mast.
