Mast stepping A frame.
I just finished a mast raising system on my Helsen 22'. It is 12v operated and is glass laid over my deck. When it is down, you can barely see it. This might be a little over the top, but take a look. You can see it on Youtube, just type in "mast stepping A frame" and you should reach it, also on my channel is a 12v operated keel, Bob.
