Rag Doll foul bottom

I guess Wes being from the midwest he didn't have any experience with the fouling a boat can get in warm salt water. I live in Belize and unfortunately do have some war stories about fouling. The first thing you notice is that the boat has no power! A propeller works somewhat like an airplane wing and when it is covered with barnacles it hardly works at all. A 100' freighter that was laid up for over a year was only able to make 3 knots instead of her regular 8! This is with a huge prop of 4 or 6 foot diameter and the barnacles were proportionately much smaller than they would be on a 28' auxiliary. Not as dramatic but also noticeable is she does not answer the helm as well with a foul rudder. All Amanda noticed is that she pulled to starboard a little.
