Hi there, I am new to sailing and just bought a 27 catalina. I had it shipped to my location so the mast was stepped. I put the mast back up myself with a crane. My question is should I have the mast tuned by someone who knows what they are doing? I have been told different things by people and not sure what to do. One person told me to tighten the turnbuckles until they are taut and this should be fine. Another told me to hire someone who knows what they are doing to "tune it". Any advise would be great. Also, the boat is in southern calif - san pedro and I want to hire someone to give me lessons. Anyone know of any reputable teachers there?.
