I have recently aquired a '70'v24. It is in good shape & I have sailed it successfully (I got back alive)3 times. I love it but have a few questions. The adjustible keel device looks like an add on. Does anyone have a picture of an original? Mine has a 4x4 acrosse right in front of the cabin with a hand winch attached. This works well but as I say it looks bad .Is there a manual for this boat?
