Here are the modifications we have made on our 1970 E-32 so far. The majority are performance mods:1. New sails Ullman kevlar medium #1, #3 and .6 symmetrical spinnaker.2. Spectra halyards3. tossed the hank-on system and went with a Tuff Luff4. new winches -- two primary Harken self tailing and two harken spin sheet non-self tailing, one vang/spin halyard composite winch5. rudder modification6. New instruments. B&G H-1000 system, including wind, speed, depth, compass, all integrated, with the tri-function display, analog wind angle and single H-100 digital displays.7. modified main outhaul.8. Navtec hydraulic backstay adjustor9. Simrad W-32 wheel pilot For performance (besides the amazing difference good sails allow), the best modifications were the instruments and the rudder. For the instruments, the ability to accurately read and display true wind direction has been amazing in detecting and capitalizing on subtle wind shifts. The rudder was modified in such a way that it was narrowed and lengthened, giving us lift up wind and better bite and control off the wind. We have found we can point 2-3 degrees higher simply because of the rudder mods.Hope that helps.Jim McConeVoice of Reason E-32-2 Hull #134
