I am trying to learn more about my 222 I bought last fall and have had a great time sailing on Buck's Lake this summer. The on-line info states that it has 800 lbs of ballast. Is this lead in the keel? I have read some earlier posts about the 1984 not having enough mast support and needing a stainless pole added. Is this really necessary? This next question may sound silly, but I have thus far had the boat heeled at about 15 degrees close hauled. Is this about max for this boat ? I realize there are many factors involved here, but a general answer would be greatly appreciated. Thanks!
