Racing an Oday 34/35
My boat is an Oday 30, but it is similar enough that what I have learned may be applicable. Initially, I had difficulty pointing high, and could only tack through 100 degrees, which was not competitive. When I measured and calculated the sheeting angles, I found my particular leads were 11.5 degrees off the centerline. So I rigged barber haulers, and pulled the sheets in to nine to ten degrees off the centerline. This let me tack through 90 degrees in most conditions. The Oday 30 is undercanvassed for light air, but a taller mast was not in my budget. I did optimize my sail inventory as best as possible, with three used Kevlar headsails from J-105s, two lightly-used symetrical spinnakers, and one new asymetrical spinnaker with a sock. These were all a help in picking up the pace. If you click on my name, you'll see a picture of the Kevlar 140 percent number two genoa in a single handed race off Los Angeles.
