Are there any photos of the mechanism? How quickly can the draught be reduced by lifting the keel? http://www.yachtforums.com/forums/showthread.php?t=3742
Here's a close up of the keel, where it attaches to the bottom of the hull. http://www.yachtforums.com/forums/showpost.php?p=17882&postcount=3
Do all lifting-keels use essentially the same type of mechanism? Because, I remember last year when Mirabella V ran aground there was much discussion about the keel having dropped, and some design sketches of lifting keels circulated about the net... maybe someone can dig one of those up...?
