|keel lock down measurements|
Here are the measurements on my 24 for the keel lock down position. My boat is a MKII. The measurements are taken from the centre of the hole to the end of the F/G. I have not measured including any timber trim as trims and c/b case tops may vary.
Case top down = 160mm Front of case aft = 370mm Bolt = 100 x 10 mm
My keel is an origional cast iron swing version. The bolt allows the keel a slight rake aft. IN heavy conditions, we rake the keel back anyway and have it hard against the bolt. the boat performs better with the keel back about 15 degrees.
I hope this helps those looking for info on the subject. Feel free to email me if you want to.
