I recently bought a 1979 O'Day 27 and so far love it. Sadly I have suffered a few sun-damage rips along the leech on my unknown age 150 Genoa which may be beyond repair (or cost prohibitive). I am pretty much an intermediate Lake Simcoe (Ontario) day sailor with weekly beer can races for fun. Do I need a 150 again or something smaller (hopefully used). I have managed the genoa no problem so far in various winds but wonder if I am over-powered. Thanks in advance.
