Catalina 22 Champ John Allen’s Speed Secrets (Editor’s Note: John Allen has proven himself to be one of AYC’s best sailors, so we asked him to write up some observations and suggestions about how to go fast on the desert. Here are what he calls some “chunterings” about sailing in Arizona. “Some are well-known,” he writes, “so skip the bits you know! Skip can skip it all.”) By John D.
