Question: What is the length (in the direction of travel) of the Austral 20 Mark 1 swing keel?

I ask because I might need to prop up the boat to drop the keel out of the keel slot, and it would be best to prop the boat high enough to get the keel out in the horizontal. I know the boat draft is about 1.53m, but I'm not sure if I can safely prop the boat 1.6m above ground. If the keel is, say 0.3m long, I know I could get it out by propping the boat, say, 0.4m above ground.

PS I have already checked John Crawford's Austral 20 Library, but couldn't find the answer.

Found a scruffy old drawing in John Crawford's library, so traced over it in AutoCAD to get a scale drawing over a lunchtime (see attached). This indicates that the keel is about 0.46m wide. Of course, there's nothing like actually measuring it, but this gives me an indication of how high to lift the boat to get to the keel.
