Ditto here on track bases. On #76 we replaced the original factory teak strip under the ss track with a 1/4'' - or so - section of "phenolic" plastic (same stuff from which the original blocks were made). The Genoa track from Ed's boat became our jib track (see photo above). The original ss Genoa track remains where Pearson put it. I'll get a photo of it when it stops raining.
