I am totally perplexed. I have a 310 Catalina hull # 101, fin keel, with a draft of 6'6"! The specs state the draft is 5'9" or in some instances 6'. Does any one have an idea why this boat has such a deep draft? Did Catalina make special order drafts? Unfortunately this boat has had two previous owners and I cannot get in touch with either one. Thanks for any suggestions.
