All this talk makes me glad I have an "old school" boat, Full keel with attached rudder with the prop in an apeture in the rudder. I sail out of the Mystic area and never alter course for Lobster pots. They pass under the keel and out the back...............nothing to snag on. To date I have not snagged a lobster pot. True, my boat is hard to dock in a slip and may not point quite as high but for my sailing area I'll take the full keel/attached rudder configuration any day over a fin keel/seperate rudder.
