Lifting Keel Dimensions

Here are the measurements of the lifting keel centre plate. Please note that the measurements were taken from a badly corroded centre plate. If you use this as a template you may have to do a bit of fine tuning with an angle grinder. Also, check the width of the slot in the keel as 1cm thickness might be too much for keels with less corrosion.
